Configuration

Flexible configurable 1-4 channel integrated micro GC system. Modular and independently operable without pre-investments for future expansion

Column Cartridge

Column cartridges include heated detector/injector zone and a column in an oven with temperature programming. Standard available column types PDMS, MS5A, U-PLT, U-BND, QS-BND and ALOX.
