Model 7032A -Autosampling System
The 7032AQ / 7032AB Autosampler automates the introduction of up to 21 MiniCans™, Bottle-Vacs™, or Tedlar® bags into the 7200 for preconcentration. The 7032A(x) is ideal for gas-phase volatiles applications where concentrations are expected to be within 0.5–200 PPBv. For higher concentrations, a loop injection valve can be added (7032AQ-L, 7032AB-L) to allow much smaller volumes to be accurately measured. With the loop injection valve installed, these autosamplers can attach directly to a GCMS without the need for preconcentration. For wider dynamic ranges in concentrations (0.05–100,000 PPBv), a 7650(x) robot is recommended to reduce exposure times to inlet lines.
The 7032A(x)-L autosampler provides 21-position loop injection automation for GCMS analysis of 0.1–200PPM VOCs sampled into Bottle-Vac™ samplers or 400mL – 1.4L MiniCans™. Two versions make it simple to order an autosampler that is configured for either MicroValves™ (7032AQ-L) or Tedlar® Bags (7032AB-L). The 7032A(x)-L can be attached directly to a GCMS with an optional cryofocuser for maximizing the resolution of light VOCs for loop sizes over 0.25cc. An electronic flow controller allows programmable splitting of sample or standards to effectively reduce volumes injected on-column. The 7032A(x)-L supports spiking of surrogates directly into each canister before analysis, greatly enhancing the reliability and defensibility of the generated data. The 7032AB-L features
The 7032A(x)-L supports spiking of surrogates directly into each canister before analysis, greatly enhancing the reliability and defensibility of the generated data. The 7032AB-L features hand tightened thumbwheels for easy, tool-free connection to Tedlar® bags with 3/16” sampling ports.
