Cyro Concentrator AutoSampler
Wasson-ECE Instrumentation has developed a new cryo-concentrator for your environmental analysis needs. The system includes a built-in 16 position autosampler for sampling from SUMMA canisters and Tedlar bags. The samples are collected on a proprietary trap that is cooled by liquid nitrogen or liquid carbon dioxide. The system is ideal for TO14/15 analyses, achieving MDLs as low as 0.400 ppt on a GCMS. The system has several key features that set it apart from the competition.
Automatic SUMMA Canister Pressurization
If pressurizing SUMMA canisters is part of your work flow, this system can help save manpower by taking care of this step for you. Each can in the autosampler is filled to a user defined pressure before sampling with a user selected diluent gas. The concentrator takes a pressure reading before the canister is pressurized and after the can is pressurized. The software then calculates a dilution factor for each canister. The data is then reported in the Agilent ChemStation data analysis report.
ChemStation AutoSampler Control
Most samplers require separate software for control of the autosampler. Our 16 position autosampler is controlled through the ChemStation software with the sequence data. This saves the user time by requiring the sequence information for each canister to be entered only once.
One Report
Avoid confusion by having one report that contains the ChemStation and Concentrator data. This helps the user to find information about the sample quickly and avoids the need to cross-reference reports from ChemStation and the concentrator. The data from the concentrator (trap load volume, canister pressure before and after pressurization, and canister pressure after sampling) are reported in the ChemStation data analysis report along side your other sequence data.
Single Stage Trapping
Our proprietary single stage trapping allows components to be concentrated and desorbed in one stage for fast sample throughout without refocusing, and without sacrificing peak width and sensitivity.
Integrated Load Volume
Not all mass flow controllers are created equal. We have recognized this as a recurring problem in concentration. The user set load volume may be different than the actual volume loaded into your trap with your current system. How do you account for this difference? We have solved this problem for you by electronically integrating the flow through the mass flow controller. This allows us to compare our peak data with actual load volumes, not theoretical load volumes, yielding greater linearity.
