|China's First Proton Transfer Reaction Mass Spectrometry|
China's first Proton Transfer Reaction Mass Spectrometry, developed by CAS Anhui Institute of Optics and Fine Mechanics, has passed a validation check. Experts panel who reviewed the instrument agree that this is the first Proton Transfer Reaction Mass Spectrometry developed by a domestic institute, with its major technical indicators reaching or being better than the requirements defined by the contract, and a test precision reaching the ppt level. While producing an emission that is much lower than the limit imposed by the state on atmospheric pollution, the instrument has been proved innovative in ion source design and isomer differentiation. The instrument can be useful for numerous applications, including online real-time trace gases test, and lung cancer diagnosing.
