7200 Cryogenic Preconcentrator

The 7200 Preconcentrator represents the next generation in GC and GCMS sample preparation systems for the analysis of vapor-phase volatile compounds. The 7200 takes the industry standard, 7100A’s 3-stage preconcentration and water management technology, and elevates it to a whole new level. Many of the past limitations often seen in rotary valve based devices are now eliminated by combining digital valve isolation control with advanced robotic autosamplers, dropping the potential for carryover and cross-contamination far below previously obtainable levels.

A Silonite-D coating throughout the flow path virtually eliminates unwanted chemical reactions, ensuring complete
recovery of volatile and light semi-volatile compounds. The 7200’s advanced water and CO2 management technologies provide superior recovery of polar and non-polar organics, while an inert heated flow path allows analysis of hydrocarbons in the range of C2–C18 (depending upon trapping configuration).

Four built-in inlets are available on the 7200 for direct sample introduction, or as inlets for multi-position autosamplers such as the 7650 and 7016D. Internal traps feature an optimized geometry that improves trap temperature consistency
during analysis. Accu-Sample technology (patent pending) combines digital valve control with direct volume measurement rather than indirect time integrated flow measurements to allow better small volume accuracy down to 10cc over a wider pressure range while permitting both air and non-air matrices to be analyzed accurately. An optional loop injection valve can be added to reduce quantitative sample volume measurements down to as low as 0.25cc (1.0cc loop typical).
