Linearity and Precision beyond belief. 3-7% RSDs across concentration ranges of 200-1000x is the new norm!!

Analyze vapor-phase volatile compounds with unmatched precision.

The 7200 Preconcentrator represents the next generation in 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.

Powerful & Intuitive Software

The 7200 comes equipped with tools for validating system performance, including the ability to perform automated leak checking and matrix spiking. Critical parameters are recorded during each sample preconcentration to verify proper system operation, such as trapping flow rates, flow volumes, trap pressure drop, trapping temperatures, water management parameters and much more. Data is stored for easy integration with Laboratory Information Management Systems (LIMS).

Ultra-Inert Flow Paths

A Silonite-D™ coated flow path throughout the 7200 virtually eliminates unwanted chemical reactions, ensuring complete recovery of volatile and light semi-volatile compounds.

Advanced Water & COManagement

The 7200’s advanced water & CO2 management technologies provide superior recovery of polar and non-polar organics, while the inert heated flow path allows analysis of hydrocarbons in the range of C2 – C18

Accu-Sample™ Technology

Accu-Sample technology 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 allowing air and non-air matrices to be analyzed accurately.
