Dr. Atsuhiko (Ash) Toyama, PhD at Shimadzu Corporation Describes the Rationale Behind the Q-TOF LC/MS that Sufficiently Sustains Sub-PPM Mass Accuracy in Webinar

Share Article

During the webinar, hosted by LabRoots on November 27, participants will learn the various metrics that are relevant to a statistical interpretation of mass measurement accuracy (MMA) and why mass resolution of 30,000 is more than adequate for mass measurement at sub-ppm accuracy. Using the Shimadzu LCMS-9030 quadrupole time-of-flight MS, the rationale and strength of instrument stability for consistently achieving sub-ppm MMA has been demonstrated in small molecules.

High-resolution, accurate-mass (HRAM) mass spectrometers (MS) are a class of MS instrumentation with capability to resolve complex sample matrix and to allow identification of compounds by measuring their accurate masses. Specifically, those coupled to liquid chromatograph (HRAM LC/MS) have been used extensively for structural elucidation of unknown compounds primarily in chemical industry (impurity analysis) and biological researches (proteomics, metabolomics, lipidomics), but also increasingly in forensic science, food safety and environmental testing. Given the recent reduction of instrumentational cost, it will not take many more years until HRAM analysis becomes a versatile tool for all industries and researches.

The key performance attribute underlying all application fields is MMA as it affords molecular specificity and reduction of false positive results. Dr. Toyama, MS Application Specialist, Analytical & Measuring Instruments Division at Shimadzu Corporation, will also share in detail how various parameters affect the accuracy of mass measurement, including a demonstration of mass drift caused by temperature change.
