7032A Autosampling Systems

The 7032A Autosamplers automate the introduction of up to 21 MiniCans,Bottle-Vacs, or Tedlar bags into the 7200 or 7100A for preconcentration. Recommended for gas-phase volatiles applications where concentrations are expected to be within 0.2 PPB to 500 PPB. For higher concentrations, a loop injection valve can be installed (7032AQ-L, 7032AB-L) to allow much smaller volumes to be accurately delivered for a wider dynamic range. With the loop injection valve installed, these autosamplers can also be attached directly to a GC or GCMS without the need for preconcentration when analyzing concentrations exceeding 0.1 PPM.

The 7032Ax-L autosampler provides 21-position loop injection automation for GC or GCMS analysis of 0.02 to >1000 ppm VOCs sampled into Bottle-Vac samplers or 100mL - 1.4L MiniCans. Two versions make it simple to order an autosampler that is congured for either Micro Valves (7032AQ-L) or Tedlar Bags (7032AB-L). The 7032Ax-L can be attached directly to a GC or GCMS with an optional cryofocuser for maximizing the resolution of light VOCs. An electronic ow controller allows programmable splitting of sample or standards to eectively reduce volumes injected on-column. Splitting makes it possible to change the amount injected without changing loops and simplies the generation of calibration curves from a single standard.

The 7032Ax-L supports spiking of surrogates directly into each canister before analysis, greatly enhancing the reliability and defensibility of the generated data. The 7032AB-L makes leak-tight connections to Tedlar bags using hand-tightened torque wheels for easy, tool free connection to Tedlar bags with" sampling ports. The ultimate detection limits possible with the 7032Ax-L autosamplers are analyzer dependent. Newer mass spectrometers are capable of detecting VOCs down to 10-20 PPB using 1.0cc loop injection and cryofocusing.
