The Advance Maxum gas chromatograph system features new chromatography tools as compared to previous models.
The Advance Maxum gas chromatograph system features new chromatography tools as compared to previous models. For instance, a single 10-port valve is designed to replace two model 11 valves and an 8-cell thermal conductivity detector performs up to six simultaneous measurements. The 10-port valve is half the size of the Model 11 valve and features pressure-on-diaphragm activation with no moving parts. It operates more than 15 million cycles on clean samples and switches gas samples up to 75 psig (5-bar). Improved electronic feed-through assemblies eliminate all oven wiring, reduce detector electronic noise with full metal shielding, and meet all international codes. They allow any detector to be attached to the same assembly. The thermal conductivity detector includes six independent measurement cells and two reference cells while a flame ionization detector includes the flame chamber plus two filament-type thermal conductivity cells.
