Perspectives from ASMS 69: Part II

 Perspectives from ASMS 69: Part II

by Dr. Robert L. Stevenson

Due to COVID-19, ASMS 2021 was held as a virtual/in-person hybrid meeting. A total of 112 firms exhibited at ASMS 69, with just over 5,000 people attending between the two meeting options. I shared some technical perspectives last week in Part I of the series, and I conclude in today’s Part II.

Isotope ratio MS requires excellent quantitation with high resolution for mass discrimination between isotopologs. The Delta Q IRMS (Isotope Ratio MS) from Thermo Fisher Scientific is designed to provide rapid discrimination between isotopologs with quantitative analysis.Since the delta mass may be small, high accuracy and precision is essential for data quality and decision support. Cited applications include tracing origin of coffee and wine, sport drug testing to differentiate natural vs. synthetic hormones, and origin of natural gas. Upon adding an LC or GC and software, the system is called the LC IsoLink or GC IsoLink.
