摘要： In the apparatus of the invention a flow of a carrier gas through a column is provided. A sample is provided in the column, and a temperature of a longitudinally short portion of the column is raised to a predetermined controlled high temperature at which volatile substances are released from the sample packing and are carried by the carrier gas. The column is cooled on each side of the short portion to a low temperature at which the volatile substances condense or adsorb on the column packing. By continuously moving the heated short portion from an inlet end to an outlet end of the packing in a direction of carrier gas flow the volatile substances selected by controlled high temperature are released. Four particularly useful and advantageous applications can be identified for the invention. Firstly, it can be used to provide an improved gas chromatograph (GC) injector. Secondly, it can be used to provide an improved thermal separator or extractor. Thirdly, it provides an efficient way to analyze target compounds (Target Compound Analysis or TCA mode) suspected of being contained within a complex mixture by allowing for the GC analysis to be carried out only on those compounds or substances falling within the same or similar thermal desorption characteristics as those of the target compound. Lastly, by operating in a full time-coupled time-resolved (TCRC) mode, a complete three-dimensional analysis output can be obtained giving better power of separation of the analyzed sample, which is of particular importance when the substance to be analyzed is a complex organic material.

摘要： The present disclosure relates to methodologies, systems and apparatus for controlling pressure in a CO 2 -based chromatography system. A first CO 2 pump operates in constant flow mode and delivers CO 2 to a chromatography column, and liquid modifier is introduced to the chromatography column according to a gradient. A second CO 2 pump is disposed downstream of the column and operates in constant pressure mode to introduce CO 2 into a flow stream at an output of the column. Liquid modifier is also introduced into the flow stream at the output of the column according to a reverse gradient compared to the gradient entering the chromatography column.

摘要： A method and apparatus is provided for increasing sensitivity for near-real-time detection of very low concentrations of diffusely distributed trace vapors in a carrier medium. Before admitting the trace vapor bearing carrier medium into a near-real-time GC/MS trace vapor detection system, the concentration of the trace vapor in the carrier medium, air in this instance, is increased by passing it through a membrane gas separator. The gas separator preferentially passes a portion of the trace vapor and rejects all but a very small portion of the carrier medium. The sample, highly concentrated in trace vapor with respect to the carrier medium after passing through the gas separator, is then compressed by a turbomolecular pump resulting in a substantial increase in density of the trace vapor at the exhaust port of the pump and a corresponding increase in detection sensitivity.

摘要： A gas chromatograph (2) and method of chromatography are provided. Analytes (112), those compounds to be tested, are extracted from a sample by moving the sample into a column (100) which has a stationary phase (109) along column walls (110). Column (100) has two sections (101, 102) which are different in length. Longer section (101) is heated and analytes (112) move to shorter section (102). Longer section (101) is then cooled and the entire column (100) is heated. The device then functions as an analytical column and analytes (112) move out of shorter section (102) through longer section (101) and out of column (100). A detector (111) placed at the end of the column's longer section (101) detects the presence of the compounds as they exit column (100). In an alternate embodiment two separate columns are provided. One column is used as the extraction column and the other is used as the analytical column.
