Chromatographic Detection

Combined with chromatography IMS provides an additional dimension to the analysis. It can often separate co-eluting components by mobility, the polarity of the drift tube or their proton or electron affinities. Selected drift time monitoring may be used in an exactly analogous way to selected ion monitoring in mass spectroscopy. Indeed, the development of GC-IMS systems by NASA to monitor continuously the air in the International Space Station has shown that GC-IMS has a near equivalent analytical capability to GC-MS - and one that can be achieved with significantly less complexity and cost. Similar developments are underway with HPLC separation, with sub-picogramme detection limits reported for many compounds. This area of activity is undergoing rapid development and it may be that IMS may come to be used as a general-purpose detection system for chromatography.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
