Enhanced surface sampler and process for collection and release of analytes

Title: Enhanced surface sampler and process for collection and release of analytes

An enhanced swipe sampler and method of making are described. The swipe sampler is made of a fabric containing selected glass, metal oxide, and/or oxide-coated glass or metal fibers. Fibers are modified with silane ligands that are directly attached to the surface of the fibers to functionalize the sampling surface of the fabric. The swipe sampler collects various target analytes including explosives and other threat agents on the surface of the sampler.

Automated position control of a surface array relative to a liquid microjunction surface sampler

Patent Van Berkel, Gary J. ; Kertesz, Vilmos ; Ford, Michael James

A system and method utilizes an image analysis approach for controlling the probe-to-surface distance of a liquid junction-based surface sampling system for use with mass spectrometric detection. Such an approach enables a hands-free formation of the liquid microjunction used to sample solution composition from the surface and for re-optimization, as necessary, of the microjunction thickness during a surface scan to achieve a fully automated surface sampling system.

Apparatus and process for collection of gas and vapor samples

Patent Jackson, Dennis G ; Peterson, Kurt D ; Riha, Brian D

A gas sampling apparatus and process is provided in which a standard crimping tool is modified by an attached collar. The collar permits operation of the crimping tool while also facilitating the introduction of a supply of gas to be introduced into a storage vial. The introduced gas supply is used to purge ambient air from a collection chamber and an interior of the sample vial. Upon completion of the purging operation, the vial is sealed using the crimping tool.

Control of the positional relationship between a sample collection instrument and a surface to be analyzed during a sampling procedure using a laser sensor

Patent Van Berkel, Gary J ; Kertesz, Vilmos

A system and method utilizes distance-measuring equipment including a laser sensor for controlling the collection instrument-to-surface distance during a sample collection process for use, for example, with mass spectrometric detection. The laser sensor is arranged in a fixed positional relationship with the collection instrument, and a signal is generated by way of the laser sensor which corresponds to the actual distance between the laser sensor and the surface. The actual distance between the laser sensor and the surface is compared to a target distance between the laser sensor and the surface when the collection instrument is arranged at a desiredmore »« less
