New Approach for the Extraction and Analysis of Volatile and Semi-Volatile Components

MonoTrap™ is a state-of-the-art tool for the extraction and analysis of volatile and semi-volatile components by MMSE (Monolithic Material Sorption Extraction).

MMSE using MonoTrap™ demonstrates a number of key advantages over alternative methods for adsorption and extraction. Conventional media for sampling generally exhibit low surface area and thin polymer coatings, which may lead to poor recovery and the need for prolonged extraction times. MonoTrap™ is based on state-of-the-art silica monolith technology. It has a large surface area due to the pores within the silica skeleton, whilst the through-pores reduce the resistance to flow. The result is a medium that requires no pre-conditioning, exhibits fast adsorption and extraction and offers complete desorption with ease.

These advantages have demonstrated excellent benefits in many areas and a range of industry applications have been identified. Copies of all application notes are available on request from Hichrom Ltd.

Sample adsorption with MonoTrap™ has been demonstrated to work using headspace sampling, direct contact sampling and passive sampling techniques. Sample extraction can be achieved using either solvent extraction or thermal desorption. Two chemistries are available with both disc and rod formats.
