Profile: Zoex Corp deals with thermal modulator. The ZX1 thermal modulation system provides the lowest practical temperature for thermal modulation and hence modulates organic compounds. It has two-stage thermal modulation that uses a continuous cold jet flow and a regularly pulsed hot jet remobilizes the trapped effluent. The ZX2 employs a closed cycle refrigerator/heat exchanger to produce -90° cold jet. Our LN2 autofill unit monitors and transfers liquid nitrogen into the heat exchange dewar provided on the ZX1. GCxGC provides a technique for resolving thousands of low molecular weight metabolites in biological fluids, from cytoplasm extracts to human breath, blood extracts, and others fluids. It can fight disease, assist in drug R&D, and supports clinical studies and toxicology. Also, GCxGC analysis of fire debris permits ready separation & identification of fire accelerants & plastic and wood pyrolysates.
