“…In contrast, polymerized layers of crosslinked polymer are physically more stable, and their preparation is more reproducible. The PLOT technique has recently been detailed in two excellent review articles 10) . Although PLOT columns containing an in situ prepared polymer layer represent a significant advance, they still must be several meters in length.…”

Porous polymer monoliths emerged about two decades ago. Despite this short time, they are finding applications in a variety of fields. In addition to the most common and certainly best known use of this new category of porous media as stationary phases in liquid chromatography, monolithic materials also found their applications in other areas. This review article focuses on monoliths in capillaries designed for separations in gas chromatography.

“…Using our packed micro-columns in 15 to 25 cm lengths, moderate success was only achieved with C3-5. In future work we hope to achieve separations of C1-12 using microfabricated porous-layer open-tubular columns, which are a cross between packed and wall-coated open-tubular 9 .…”

The natural gas industry seeks inexpensive sensors and instrumentation to rapidly measure gas heating value in widely distributed locations. For gas pipelines, this will improve gas quality during transfer and blending, and will expedite accurate financial accounting. Industrial endusers will benefit through continuous feedback of physical gas properties to improve combustion efficiency during use. To meet this need, Sandia has developed a natural gas heating value monitoring instrument using existing and modified microfabricated components. The instrument consists of a silicon micro-fabricated gas chromatography column in conjunction with a catalytic micro-calorimeter sensor. A reference thermal conductivity sensor provides diagnostics and surety. This combination allows for continuous calorimetric determination with a 1 minute analysis time and 1.5 minute cycle time using air as a carrier gas. This system will find application at remote natural gas mining stations, pipeline switching and metering stations, turbine generators, and other industrial user sites. Microfabrication techniques will allow the analytical components to be manufactured in production quantities at a low per-unit cost.Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin
