摘要： A silica-based stationary phase for chromatography columns and the methods of preparing such. More particularly, but not by way of limitation, a silica-based stationary phase that is substantially free of polyethers (e.g., polymer glycols). Also, a chromatography column comprising a silica-based stationary phase substantially free of polyethers (e.g., polymer glycols) within its channels as either a thin-film coating and/or a monolith and/or a monolithic coating. More particularly, a micro-electro-mechanical system (MEMS) chromatograph comprising a silica-based monolith substantially free of polyethers (e.g., polymer glycols) as the stationary phase within the micro-channels of the column.

摘要： A fast field mud gas analyzer is presented. The fast field mud gas analyzer has a splitter system; a plurality of analytical lines composed of a micro chromatographic column and one or more detector; one or more heating element; and a computer system. The splitter system selectively applies a portion of an effluent sample flow through one or more outlets. The analytical lines are in fluid communication with the splitter system and receive at least a portion of the effluent sample flow. The micro chromatographic column separates portions of the effluent sample flow. The detector analyzes the separated portions and generates information indicative of analysis of the separated portions. The heating element heats the portion of the effluent sample flow within the analytical line. The computer system controls the splitter system and the one or more heating element and receives the information from the detectors.
