The 7016CA performs a unique "double sample flush" to help eliminate any carryover from the precious sample. The first flush occurs as a final step before baking out the preconcentrator during the previous sample analysis.
The heated rotary valve in the 7016CA then remains on the next sample position while the previous sample is being analyzed by GC(MS), eliminating the potential for cross contamination as rotary valves rotate past sample ports that are at higher pressures. A second flush occurs during the sample preconcentration just before drawing a requested volume of sample into the 7000/7100 Preconcentrator.
The 7016CA is intended for low concentration samples in the range of a few PPM to sub-PPB. For samples ranging from PPB to % levels, the 21 position 7032-L autosampler supports the ability to inject smaller sample volumes (10 to 2000µl) and can operate with or without a preconcentrator.
