MULTIDETEK 3

Functionality of two GCs in one plus trace moisture and O2

The MultiDetek3 is the latest development of our popular range of compact industrial gas chromatographs. It is more than a simple gas chromatograph: it’s a modular process GC instrument, that combines the functionality of two GCs in one with the ability to also monitor trace moisture and oxygen online.

The instrument has been completely redesigned and features an extra-large 15.6” touch screen for easy visibility and operation. It has a dual sample inlet and online modules which allow simultaneous stream analysis of trace moisture and oxygen together with trace impurities. It is temperature controlled for improved stability and performance. The software interface is our latest LDChroma+, which offers more sophisticated data management and a planning platform.
