摘要： A thermal desorption tube collection system uses a thermoelectric cooler to collect and concentrate gas samples. In some modes, the operation of the cooler is reversed to flow the concentrated sample directly into a separator such as a gas chromatography system. Components resolved in time by a thermal desorption separator accumulate in a sample cell and are analyzed by electromagnetic radiation-based spectroscopic techniques. Also presented are methods for analyzing biogas samples.

摘要： A method and system for sample analysis involve a temporally-resolving separation of sample components. In the method, solvent vapors are condensed prior to entering a temporally-resolving separator, a GC column, for example, and solvent-depleted vapors are directed to the separator where constituents are resolved in time. A system for analyzing a sample comprises an injection port, a temporally-resolving separator (e.g., a GC column) and a conduit connecting the two. The injection port is at a temperature sufficiently high to vaporize the solvent and analytes present in a sample. The conduit is configured and/or operated to condense the solvent, while maintaining the analytes in the vapor phase.
