JMS-T100GCV is a reflectron time-of-flight (reTOF) mass spectrometer. Temperature of the GC-transfer line was 200 C. Resolving power (FWHM, nominal) was 7,000.
Field ionization (FI) voltage, which is defined as the voltage between the emitter surface and the electrode, was 10 kV (default). Typical accuracy level expected was 10 ppm. Postrun m/z adjustment was made at a known mass, 140.0837.
This record was created by the financial support of MEXT/JSPS KAKENHI Grant Number 20HP8016 to the Mass Spectrometry Society of Japan.
