A gas chromatography system comprising a sample introduction device, an oven coupled to the sample introduction device and a detector coupled to the oven is disclosed. In certain examples, the oven may be configured to receive a chromatography column in a space in the oven. In some examples, the oven may be constructed and arranged to provide a substantially constant temperature to the space during an analysis stage of the gas chromatography system.

Methods and devices for circulating air

Disclosed are systems and methods that include a thermal desorption unit, a chromatographic column, and an interface device between the unit and the column. The interface device controls the fluid flowing into the column, such as by providing additional carrier gas to maintain a substantially constant gas flow or velocity, by proving a controlled temperature increase, or by venting a portion of the gas received from the thermal desorption unit, thereby removing the dependence on the thermal desorption unit for such control. In some embodiments, the interface is a chromatographic injector. In certain embodiments, a transfer line from the desorption unit is coupled to the same port of the interface device as the chromatographic column. In some of these embodiments, this is accomplished by employing a special adaptor.

Chromatographic interface for thermal desorption systems

An ion optical system including an ionizer for ionizing one or more compounds, the ionizer including a plurality of components, a mass separator for separating ions of the one or more compounds, the mass separator including a plurality of components, and a detector for identifying the one or more compounds, the detector including a plurality of components. At least one of the plurality of components of at least one of the ionizer, mass separator and detector includes a composition of zirconium oxide and aluminum oxide.
