Detailed Description
The Agilent 7890B GC is the world’s most widely used GC system. It features accurate temperature controls (+4°C to 450°C) and precise injection systems, plus enhanced Electronic Pneumatic Control modules for best retention times. This is coupled with a Hiden Analytical HPR-40 DEMS, which scans the electrochemical potential and applies mass spectrometry to analyse the products. Typical scanning speeds are around 1 mV/s with a typical scanning range of 0 to -1.5V.
Uses/Applications
GC-DEMS is an analytical technique that allows the separation and in situ mass resolved determination of gaseous or volatile reactants, reaction intermediates and products from electrochemical reactions. Hiden’s quadrupole mass spectrometer systems address a broad application range in: vacuum, gas, plasma and surface science.
