New approach for sample adsorption and extraction of volatile and non-volatile components
GL Sciences MonoTrap™, available from Hichrom Limited, is a new generation tool for sorptive extraction of volatile and non-volatile
components of interest to many industries including the perfume and cosmetic, food and beverage, forensic, toxicology, environmental, chemical and biochemical and many others.
MonoTrap™ demonstrates a number of key advantages when compared to alternative methods for adsorption and extraction of volatile and non- volatile components. 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 media that requires no pre-
conditioning, exhibits fast adsorption and extraction and offers complete desorption using only small solvent volumes.
These advantages have demonstrated excellent benefits in many areas and a range of industry applications have been identified including analysis of cherry blossom, red wine, body odours, soap, lavender, fatty acids in the atmosphere, organic solvents in the atmosphere, coffee, tea, gasoline residues, mango juice, curry powder, bread and non-polar metabolites from human plasma. Further application areas are continually being identified. Copies of all application notes are available on request from Hichrom Limited at
technical@hichrom.co.uk along with sample packs, demonstration video CDs and technical brochures.
MonoTrap™ has been demonstrated to work in head space sampling, direct contact sampling and passive sampling techniques. It is available in two chemistries: one has the same characteristics as silica gel, whereas the silica frame of the other contains activated carbon as an adsorption surface to aid retention of more polar components. Both types are bonded with C18 groups. Disc and rod formats are available.

Free Demo Software offer for GPC/SEC users. ParSECTM from
Brookhaven Instrument Corporation is a powerful new suite of software for multi detector, macromolecular characterization and represents the most significant development in GPC/SEC analysis for
many years. ParSEC is compatible with ALL GPC/SEC systems and detectors. Many attractive and practical features have been written into the new software for the benefit of chromatographers, including “function
specific” views, ensuring the uncluttered display of information relevant to the task at hand, customizable display and annotation options for all graph types, plus a Database approach for practical storage and archiving of data and results associated with any application.
A key benefit of ParSEC is that even though it is a powerful and fully featured software package, unlike other multi-angle, multi-detector software, it is very intuitive and remarkably easy to learn and use.
ParSEC is also capable of collecting and analyzing data from virtually all chromatographic detectors no matter whom the manufacturer is, making it the ideal “drop in” replacement for all other GPC/SEC software currently available.
