Delivery of an analysis system for sampling experimental gas samples including installation, commissioning, proof of full functionality and instruction/training

The subject of this contract is the delivery of an analysis system for the sampling of experimental gas samples including installation, commissioning, proof of full functionality and instruction/training.

In its B1 department in the field of energy resources, the Federal Institute for Geosciences and Natural Resources (BGR) conducts a wide range of experimental investigations on geochemical and microbial reactions in the deeper subsurface on questions in the fields of mineral raw materials, final disposal, use of the deeper subsurface and energy resources. For this purpose, an analysis system for the detection of gases, volatile organic and sulfur-containing compounds was procured in 2012 and analytical methods were established that provided essential insights, e.g. for the conversion of organic material into host rocks during heating in experiments or in natural systems in sedimentary basins and on hydrogen-rich hydrothermal systems.

Due to the different types of samples - from gases to liquid aqueous samples - the analysis system must have different sample feeding options. In addition, due to the wide range of compounds to be analyzed, detection after gas chromatographic separation must be carried out by various sensitive detectors operated in parallel. The use of isotope-linked compounds/internal standards and also the identification of unknown compounds requires a mass spectrometric detector, the sensitive quantification of sulfur compounds from mixtures requires a sulfur-selective chemiluminescence detector, the sensitive quantification of CH-containing organic compounds requires a flame ionization detector.
