ZX1 Thermal Modulation
The ZX1 thermal modulation system provides the lowest practical temperature for thermal modulation, hence modulates the widest range (C2 to C55) of organic compounds. Even methane has been modulated with liquid nitrogen cooled gas jets like those in the ZX1. Our improved cryogenic heat exchange system minimizes LN2 usage. Installation and use are extremely simple.
This system is time tested and robust. Sharpest known modulation gives sharpest secondary peaks, hence highest possible secondary peak capacity. Benefits like higher sensitivity than non-thermal modulators due to peak focusing. Compatible with MS at ordinary flow rates, unlike non-thermal modulators.
Benefits:
-
Easy to install; most users can manage own installation within 2 hours
-
Can be uninstalled and allow GC to be used for other methods. Not necessary to have dedicated GC
-
More robust than the quad jet
