Abstract:
Most current chromatographic instrumentation has been designed for stationary use on a laboratory bench; however, this situation is rapidly changing as analysts become more interested in smaller systems, faster analysis and portability. Portability can merely provide easy movement within the laboratory to facilitate coupling to other instruments or apparatus, installation in a manufacturing facility, or transport to remote locations for field use, such as environmental monitoring. On-site analysis eliminates problems related to loss of sample integrity during transport and storage, and greatly reduces the time required for testing and reporting.
With respect to both gas chromatography (GC) and liquid chromatography (LC), electrical power usage, column robustness and interfacing, and minimization of consumables for compliance with green chemistry principles, have become the most difficult challenges, especially when the preeminent desire is to retain high chromatographic performance. Advances in resistive heating technologies and microchip column formats have been made to address requirements for portable GC, but interfacing and temperature uniformity can be a challenge. In LC, capillary columns packed with very small particles (i.e., In this presentation, advancements in portable GC, GC-MS, LC that have led to instrumentation that has recently been commercialized will be described. These include robust capillary column technologies for both GC and LC (open tubular, packed capillaries, and microchip columns), novel temperature programming techniques for high temperature GC, calibration and sampling for portable GC-MS, “plug-and-play” column cartridges for capillary LC, and serial LC column arrangements with dual-wavelength on-column UV-absorption detection for positive target analyte detection. Applications related to petroleum and fuels, environmental analysis, and process stream monitoring will be described.
