ZX1 Thermal
Modulator
The ZX1 loop modulator has long held the world record for the number of organic molecular species separated in a single chromatographic analysis.
Capable of modulating all organic compounds amenable to gas chromatography, the ZX1 remains the unchallenged performance product in the GCxGC field.
