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.* (All necessary hoses are supplied, though not featured in diagrams at right.)
*Contact Zoex about modulating methane and ethane.
