<p><strong>Interlaboratory comparisons (ILCs) have been used for more than a century and many important concepts are linked to them. This leaflet addresses the basic terminology of ILCs, why some colloquial terms can be misleading or misunderstood, and the importance of harmonisation.&nbsp;</strong></p><p>An ‘ILC’ is the <i>organisation, performance and evaluation of measurements or tests on the same or similar items by two or more laboratories in accordance with predetermined conditions</i> [1]. ILCs have a variety of overall – and detailed – objectives, the three most common [2] being:</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Let_s_call_a_PT_scheme_a_PT_scheme_3_9993b9fb0f.jpg" alt="Eurachem: Let’s call a PT scheme a PT scheme" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Let_s_call_a_PT_scheme_a_PT_scheme_3_9993b9fb0f.jpg 245w," sizes="100vw" width="1516" height="472"></p><h4><strong>Some comparisons have special names&nbsp;</strong></h4><p>The evaluation of participant (laboratory, organisation or individual) performance is typically referred to as ‘<strong>proficiency testing</strong>’ (PT) or ‘<strong>external quality assessment</strong>’ [1]. When the main objective is evaluating the performance of, for example, a candidate standard method, the ILC is often called a ‘<strong>method performance study</strong>’ or a ‘<strong>collaborative study</strong>’ [2, 3]. The former is quite clear whereas wording such as “<strong>collaborative</strong>” and “<strong>cooperative</strong>” just stresses joint effort. A project aimed at producing a new certified reference material may involve several laboratories conducting analyses on agreed properties [4]. Not surprisingly, this work is sometimes labelled as a ‘<strong>material certification study</strong>’. Special ILCs used to demonstrate measurement capabilities of National Metrology Institutes are called ‘<strong>key comparisons</strong>’, ‘<strong>supplementary comparisons</strong>’, and ‘<strong>pilot studies</strong>’ [5].&nbsp;</p><h4><strong>Some terms can be confusing&nbsp;</strong></h4><p>Other terms for ILCs, including ‘ring test’, ‘round robin’ and ‘circle analysis’, are common in the literature. They have, however, been used for different objectives and different designs and may be ambiguous or understood differently by laboratory staff. The use of these terms may, for example, imply a specific way of distributing the ILC sample. ISO/IEC 17043 uses ‘sequential scheme’, for a PT where a unique item is transferred between the participants and ‘simultaneous scheme’, in which similar items from a batch are distributed simultaneously to the participants [1].&nbsp;</p><p>Terms like ‘<strong>measurement audit</strong>’, ‘<strong>interlaboratory testing scheme</strong>’, ‘<strong>measurement comparison scheme</strong>’, ‘<strong>rapid performance evaluation scheme</strong>’ and ‘<strong>intercalibration</strong>’ may not correctly reflect the category of laboratory involved, or the type of work participants do during the ILC.&nbsp;</p><p>When in 1994 the IUPAC defined and described three major types of ‘interlaboratory studies’, the word ‘study’ was preferred to synonyms such as ‘trial’, ‘exercise’, ‘test’, ‘evaluation’ or ‘check’ [2].</p><h4><strong>Let’s try to harmonise&nbsp;</strong></h4><p>Many laboratory staff are unaware of official terms related to ILCs but recognise the acronym PT and words like ‘ring test’. Ideally, we would use a common scientific language, but harmonisation is time consuming. Terms appear and disappear and definitions change. The same term can be defined differently, even in different international standards. Lack of standards and guidelines in local languages can cause confusion and contribute to spreading of less appropriate terms.&nbsp;</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Let_s_call_a_PT_scheme_a_PT_scheme_2_820043ce8b.jpg" alt="Eurachem: Let’s call a PT scheme a PT scheme" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Let_s_call_a_PT_scheme_a_PT_scheme_2_820043ce8b.jpg 234w," sizes="100vw" width="1006" height="671"></p><p>Much confusion can be avoided by clear reference to relevant standards and sectoral guides. ISO/ IEC 17043 [1] and ISO 13528 [6] contain many important concepts related to PT schemes and other ILCs. Some of these are also incorporated into ISO/IEC 17025 [7]. Additional useful, and free, tools are the Eurachem PT Guide [8] and the ISO online browsing platform [9].&nbsp;</p><p>In writing guidance and instructions, remember that the term ‘interlaboratory comparison’ has a broad meaning and can be used for all cases described above. Sometimes this is clear enough for the reader. In other cases, use acknowledged terms that reflect the detailed objective of the ILC. Let’s call a PT scheme a PT scheme!</p>

Agilent Technologies: Dual-Cell System (DCS) and Advanced Helium Mode (AHM)</strong></h3><p><strong>Technological developments for higher sensitivity and better interference removal than traditional He-KED</strong></p><ul><li>Technical note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/te_batch_conversion_tool_9500_icp_ms_5994_9214en_agilent_0a1bba76e2.pdf"><strong>Full PDF for download</strong></a></li></ul><h4><strong>Evolution of Agilent’s Collision Reaction Cell (CRC) technology&nbsp;</strong></h4><ul><li><strong>2001: </strong>Launched the first ICP-MS with CRC—the Agilent 7500c with Octopole Reaction System (ORS)&nbsp;</li><li><strong>2011:</strong> Introduced High Energy Helium Mode (HEHe) using Collision Induced Dissociation (CID)&nbsp;</li><li><strong>2012: </strong>Released the world’s first Triple Quadrupole ICP-MS—the Agilent 8800 ICP-QQQ&nbsp;</li><li><strong>2016:</strong> Launched the second generation Triple Quadrupole ICP-MS with Axial Acceleration—the Agilent 8900 ICP-QQQ&nbsp;</li><li><strong>2026: </strong>Introduced the innovative Dual-Cell System (DCS) and Advanced Helium Mode (AHM) for the Agilent 9500 ICP-QQQ</li></ul><p>Collision/Reaction Cell (CRC) technology is now a standard feature in modern ICP-MS systems, providing a reliable means of eliminating spectral interferences that compromise data quality. ICP-MS systems with integrated CRCs range from single quadrupole (SQ) ICP-MS used in environmental and food analysis, to triple quadrupole ICP-MS (ICP-QQQ) for advanced research applications. For routine applications, Helium Kinetic Energy Discrimination (He KED) mode, commonly referred to as helium mode (He mode), is the most widely used CRC operational mode. The widespread use of He mode is due to its universal effectiveness in reducing a broad range of polyatomic interferences without the need for element-specific optimization.&nbsp;</p><p>Unlike CRCs that rely on reactive cell gases and require complex tuning (often referred to as reaction cells), He mode effectively mitigates many commonly occurring polyatomic ion interferences without the need for intricate adjustments. In contrast, reaction cells often require careful selection of gas type (such as ammonia or oxygen) and tuning parameters based on the specific interfering ions on analytes of interest.&nbsp;</p><p>Building on the simplicity of He mode, Agilent has developed Advanced Helium Mode (AHM) for the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=9500"><strong>Agilent 9500 Triple Quadrupole ICP-MS (ICP-QQQ)</strong></a>. AHM represents a breakthrough in interference removal technology, enabled by the newly designed Agilent Dual-Cell System (DCS) and high-speed cell voltage control. These innovations deliver high sensitivity across the mass range and superior interference removal performance for routine applications. Compared to conventional He mode, AHM demonstrates the following improvements:</p><ul><li>Around a 20-fold sensitivity improvement for low-mass elements, such as beryllium (Be) and boron (B)&nbsp;</li><li>Around a 2-fold improvement for mid-to-high mass elements&nbsp;</li><li>A reduction of more than 33% in data acquisition time while maintaining detection limits (DLs), accelerating analytical measurement times&nbsp;</li></ul><p>AHM not only replaces traditional He KED but also consolidates multiple tuning modes including no gas, He, and HEHe into a single, streamlined mode. Integrated into the 9500 ICP-QQQ, AHM is a next-generation standard He mode that is faster, simpler, and delivers higher performance than its predecessor. This technical note describes the performance enhancement mechanisms of the DCS and AHM. It also includes some comparative results with conventional He KED mode to highlight the analytical improvements of AHM.</p><h4><strong>Overview and advantages of AHM&nbsp;</strong></h4><p>Typically, multi-element ICP-MS methods apply no gas mode to the determination of low-mass elements like Be and B due to low sensitivity in traditional He KED mode. Consequently, many routine ICP-MS applications have required multiple tune setups, combining no gas, He, and HEHe. Each mode switch introduces a delay due to cell pressure stabilization requirements.&nbsp;</p><p>In practice, low-mass elements (m/z &lt; 23) are generally unaffected by polyatomic ion interferences, so KED is often unnecessary. Therefore, in AHM, different voltages are applied to the DCS (effectively disabling KED) for low-mass elements, while keeping standard settings for elements with m/z ≥ 23.&nbsp;</p><p>The DCS voltages are dynamically switched in sync with Q2 using a high-speed voltage control circuit, providing over 20× sensitivity improvement for low-mass elements compared to conventional He mode. AHM eliminates the need to run in no gas mode, greatly simplifying the method. As a default approach, AHM alone is suitable for most applications.<sup>1</sup></p><h3><strong>2. Shimadzu: Damping Force Characteristic Test of Suspension Struts [JASO C611]</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_01017_en_2fbbb9c247.pdf"><strong>Full PDF for download</strong></a></li></ul><h5><strong>User Benefits</strong></h5><ul><li>Damping force characteristic tests on suspension struts can be performed based on the JASO C611 standard.&nbsp;</li><li>Combination test enables automatic speed change and measurement.&nbsp;</li><li>High responsiveness of the EMT series enables testing at high excitation speed.</li></ul><p>Various components play an important role in achieving a comfortable ride in vehicles. Among them, the suspension strut used in the suspension system is an important component that stabilizes the vehicle body by mitigating the impact caused by uneven road surfaces.&nbsp;</p><p>“JASO C611 Suspension Struts for Automobiles”1), a standard of JASO (Japanese Automotive Standards Organization), established by JSAE, specifies the definition, quality, and test method for suspension struts. There is no international standard that is equivalent to JASO C611.&nbsp;</p><p>In order to improve the performance of suspension struts, it is necessary to measure the damping force against speed by changing the excitation speed. The performance of suspension struts can be confirmed by measuring the response, such as the relationship between speed and damping force and the Lissajous waveform.&nbsp;</p><p>This article introduces an example of the test method “Damping Force Characteristic Test” specified in JASO C611, which was conducted on a Shimadzu EMT series electromagnetic fatigue testing machine.</p><h4><strong>Testing Equipment&nbsp;</strong></h4><p>The EMT-1kNV-50 electromagnetic dynamic and fatigue testing machine was used in this test. Fig. 1 shows a photograph of the testing machine. The electromagnetic actuator with extremely high frequency response enables highly accurate dynamic testing. In this test, the maximum test speed was 0.6 m/s. The EMT seriesis most suitable for testing at such high frequencies.</p><h4><strong>Conclusion&nbsp;</strong></h4><p>A damping force characteristic test on a suspension strut based on JASO C611 was conducted using an EMT series electromagnetic fatigue testing machine and Windows software for 4830. The test conditions were set using the excitation speed, and it was confirmed that the test was accurately controlled as set. The standard “JASO C611 Suspension Struts for Automobiles” referred to this time is derived from “JASO C602 Automotive Parts - Telescopic Shock Absorbers for Suspension Systems”2). Although C602 also prescribes a damping force characteristic test, it is almost equivalent to the C611, and the test machine configuration can be used by replacing the jig.</p><h3><strong>3.

<p><strong>Capturing Dynamic Insights with Live Cell Imaging</strong></p><p>During this webinar, guest speaker Dr. Helge Ewers, Professor for Membrane Biochemistry at the Freie Universität Berlin Institute for Chemistry and Biochemistry, will discuss his work investigating plasma membrane (PM) dynamics. Learn how single particle tracking and super-resolution microscopy unravel how actin rings influence the PM of cells.&nbsp;</p><p><strong>Presenter's Abstract</strong></p><p>The compartmentalization of the plasma membrane (PM) is a fundamental feature of cells. The diffusivity of membrane proteins is significantly lower in biological than in artificial membranes. This is likely due to actin filaments, but assays to prove a direct dependence remain elusive. We recently showed that periodic actin rings in the neuronal axon initial segment (AIS) confine membrane protein motion between them. Still, the local enrichment of ion channels offers an alternative explanation. Here we show, using computational modeling, that in contrast to actin rings, ion channels in the AIS cannot mediate confinement. Furthermore, we show, employing a combinatorial approach of single particle tracking and super-resolution microscopy, that actin rings are close to the PM and that they confine membrane proteins in several neuronal cell types. Finally, we show that actin disruption leads to loss of compartmentalization. Taken together, we here develop a system for the investigation of membrane compartmentalization and show that actin rings compartmentalize the PM.</p><blockquote><p><strong>Presenter:</strong> Helge Ewers, Ph.D. (Professor for Membrane Biochemistry, Freie Universität Berlin Institute for Chemistry and Biochemistry)</p></blockquote>
