1. Metrohm: Comparison of SPELEC RAMAN and standard Raman microscopes

• application note

Larger laser spot size can provide representative results with a single measurement

Standard Raman microscopes are traditionally used to perform Raman measurements or Raman spectroelectrochemical experiments when they are coupled with electrochemical equipment. Raman spectra collected with confocal microscopes allows the characterization of very small areas. However, these instruments can exhibit several limitations. SPELEC RAMAN, a new generation of spectroscopic and spectroelectrochemical instruments, offers powerful and interesting features to overcome these issues. In this Application Note, a detailed comparison is made between the main features of a standard Raman instrument and the SPELEC RAMAN by analyzing the results obtained with both instruments.

CONCLUSION

SPELEC RAMAN exhibits a number of competitive advantages over standard Raman microscopes. For instance, the spot size of SPELEC RAMAN allows the characterization of a large area in a single experiment, obtaining representative results with only one measurement. The versatility of the Raman probe is demonstrated since it can be used with different cells. The portability as well as the simplicity of SPELEC RAMAN facilitate the performance of optical experiments. It also ensures the synchronization of electrochemical and optical signals in case Raman spectroelectrochemical measurements are carried out. In addition, DropView SPELEC software allows realtime acquisition of the data and the performance of operando measurements. The easy data treatment and analysis of the results is done using one-click tools.

3. Agilent Technologies: Study of Localization of Endogenous Metals on Thin Tissue Sections by LA-ICP-MS

• Application Brief

Multi-element analysis of biological samples using laser ablation with an Agilent ICP-MS

LA-ICP-MS provides bioimaging and metallomics data

Bioimaging and metallomics are complementary fields of study that explore the role of analytes and metals in biological systems. Bioimaging visualizes the presence or absence of certain tissues, cells, and low molecular weight compounds while metallomics seeks to understand the functions and roles of metals in biological structures. Analytical techniques such as liquid-chromatography-inductively coupled plasma-mass spectrometry (LC-ICP-MS), single cell-ICP-MS, and laser ablation (LA) ICP-MS have been used for protein quantification1 , single cell analysis2 , and bioimaging, respectively.

LA-ICP-MS can provide detailed information about the localization of elements on the surface of solid samples, as demonstrated in this study for the investigation of the distribution of metals on thin sections of biological samples.

4. Thermo Fisher Scientific: Combining full spectrum read-out and innovative automation capabilities for the robust and fast analysis of major and trace elements in fertilizers using ICP-OES

• Application note

Keywords: ICP-OES, robustness, method validation, sensitivity, Step Ahead, limits of quantitation, analytical testing, toxic elements

Goal: To demonstrate the capabilities of the Thermo Scientific™ iCAP™ PRO XP ICP-OES Duo instrument, in conjunction with the Thermo Scientific™ iSC-65 Autosampler, for the fast and robust elemental analysis of fertilizers.

Conclusions: This application note presents a fast and optimized method for the quick, accurate, and robust analysis of major and trace elements in fertilizers using the iCAP PRO XP ICP-OES Duo instrument and the iSC-65 Autosampler. The highlights of the study are listed below:

• A quick and simple method with a run time of 36 s per sample for all target elements in fertilizers has been developed. This has been achieved using the excellent sensitivity in radial mode and the fast data acquisition capabilities of the iCAP PRO XP ICP-OES Duo instrument using the iFR mode. Due to the fully simultaneous acquisition across the full optical spectrum, an additional exposure can be eliminated, offering a 50% reduction of the time required for data acquisition.
• The use of the Step Ahead feature available on the iSC-65 Autosampler compliments the speed of the iCAP PRO XP ICP-OES Duo instrument and the chosen settings in this method by enabling rinsing parallel to data acquisition. The combination of both provides the opportunity to reduce sample turnover times further by almost 30% compared to a standard setup.
• The method allows achievement of the typically required limits of quantification for commonly regulated elemental contaminants in fertilizers—such as As, Cd, Cr, Hg, Ni, and Pb—with respect to the criteria prescribed in the Regulation (EU) 2019/1009. At the same time, it is capable of covering a large linear dynamic range of 0.01–20 mg·kg-1 for trace elements and 1–1,500 mg·kg-1 for elements present in higher concentrations. If the total concentration of Cr is found to be higher than the specified limit, then a speciation technique may be used to determine the amount of Cr (VI) present in the samples. The concept of the application can be easily extended to other sample types, such as soil or wastewater analysis. ICP-MS instruments can also benefit from single mode measurement and the high-speed capabilities of the iSC-65 Autosampler.²
• Continuous, uninterrupted measurements of >5 hours covering more than 500 unknown samples proves the accuracy and unmatched robustness of the developed method, which makes the iCAP PRO XP ICP-OES Duo instrument an ideal choice for high productivity analytical testing laboratories.
