MonoTrapTM is a
state-of-the-art tool for the
extraction and analysis of volatile and semi-volatile components by MMSE (
Monolithic
Material
Sorption
Extraction),
which will be of interest to many industries including the perfume and
cosmetic, food and beverage, forensic, toxicology, environmental, chemical and
biochemical.
MMSE
using MonoTrap
TM demonstrates a number of
key advantages when compared
to alternative methods for adsorption and extraction of volatile and
semi-volatile components (eg SBSE, SPME). 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
TM 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 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.
Sample adsorption with MonoTrap
TM 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 the latest thermal
desorption products. Two chemistries are available: one has the same
characteristics as silica gel, whereas the silica frame of the other contains
activated/graphite 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.
