Certain embodiments described herein are directed to devices that can be used to align the components of a source assembly in a source housing. In some examples, a terminal lens configured to couple to the housing through respective alignment features can be used to retain the source components in a source housing to provide a source assembly.

Assemblies for ion and electron sources and methods of use

An analyte of a sample is transferred to an analytical instrument by introducing a quantity of a compound of a standard material into a vessel containing an adsorbent material; introducing a quantity of the analyte of the sample into the vessel; and transferring the analyte of the sample and the compound of the standard material to the analytical instrument.

Method for verifying the integrity of thermal desorption sampling tubes

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.
