• Webinars covering helium mode interference removal, qualifier isotope validation, and multi-element calibration strategies.

Main Results and Discussion

• Over 140 units of the 7700 Series were sold within three months of launch, prompting near-capacity production at Agilent’s Tokyo Analytical Division.
• Envirolab Services achieved NATA accreditation for its 7500 Series instrument within two months, validating ORS-enabled low-level selenium and arsenic quantitation in seawater and complex matrices.
• AF4-ICP-MS profiling in Great Salt Lake brines identified distinct nanoparticle size fractions (0.9–7.5 nm, 10–250 nm, >450 nm) carrying trace metals (Mn, Pb, Zn, Cu, U, Ni, Co, As, Hg), revealing redox-driven speciation and potential biouptake pathways.
• IDEA™-MS with CCFQ eliminated calibration curves, delivering definitive accuracy in multitarget speciation of mercury species and streamlining workflows for environmental and biomedical applications.
• The ICP-MS Training Facility’s combined laboratory/lecture format and limited class sizes enhanced participant engagement and technique proficiency, as evidenced by positive feedback.
• Upcoming webinars and user group events focus on leveraging helium collision mode to expand analyte coverage, employing qualifier isotopes for data validation, and sharing best practices in tuning and maintenance.

Practical Benefits and Applications

• Pharmaceutical, environmental, and industrial laboratories gain rapid access to high-throughput, interference-free ICP-MS systems.
• Environmental testing labs shorten accreditation timelines and improve detection limits for key pollutants.
• Geochemical and ecological researchers can assess natural nanoparticle distributions and metal cycling in extreme environments.
• Regulatory and quality-control workflows are streamlined through calibration-curve-free isotope dilution, reducing error sources and enhancing legal defensibility.
