MonoTrap

TM

The Ultimate Technology for
Sample Concentration
MonoTrap is a newly-developed, state-of-the-art sorptive media, based on the high surface area of silica monolith technology.
It's designed for simple and rapid enrichment of flavors, aromas, and fragrances, and can be easily used for the analysis of volatileand semi-volatile compounds for quality control, environmental, and forensic applications.

Silica Monolith Structure
The large surface area provided by the three dimensional silica monolith's network of through poresand mesopores oﬀers unmatched adsorption and desorption eﬃciency.

Outline of adsorption
Samples are adsorbed on the surface of silica monolith structure
either comically modified or embedded withactive carbon or graphite carbon.

SampleThrough Pores and Meso Pores provide over 150m2/g surface area,
therefore small hybrid adsorbent

Monolithic Material Sorptive Extraction

Features■Easy-to-use■Hydrophobic Surface

MonoTrap performs a very low blank, it can be used directly without any
conditioning.

MonoTrap's monolithic network is functionalized using hydrophobic ODS
groups, therefore, MonoTrap will not adsorb water from aqueous samples.
No need to worry about injecting water onto your GC or GC/MS whenusing MonoTrap as with liquid-liquid extraction or other sorptive media.
This also allows for the addition of ionic salts to improve sample adsorption
with MonoTrap.

■Highly Efficient Adsorption
MonoTrap's large surface area oﬀers larger sample loading capacity,
ensuring a higher concentration of adsorbed compounds.

■Complete Desorption with
low Solvent Volume■Multiple Injections & Analyses

It only takes a small amount of solvent, 200 µL, to completely saturate themonolithic network and achieve desorption, though more solvent can beused to control the final concentration of your samples.

Because compounds adsorbed to MonoTrap can be extracted using 200 µL(or more) of organic solvent, it is no problem to perform multiple injections ofyour sample. With MonoTrap, it is even possible to make injections on diﬀerent
GC systems utilizing diﬀerent column phases! Solvent extraction can even be
accomplished within a GC autosampler vial using the rod shaped MonoTrap.

The graph on the right shows a comparison between the recovery rate of DCC18(containing activated carbon) and DSC18 (containing only ODS groups). For a
relatively non-polar compound such as Indole, both the MonoTrap DCC18 and
DSC18 have approximately the same enrichment capabilities.

Caprylic acidWith more polar compounds, such as Methylpyrazine, the activated carbon
groups on the MonoTrap DCC18 do a much better job of enrichment than the
MonoTrap DSC18, which contains only hydrophobic ODS groups.

Monolithic Material Sorptive Extraction● MonoTrap performs high recovery
MonoTrap DCC18 shows high recovery rates for low to high logP compounds and hydrophilic to hydrophobic compounds. Unlike other products for whichusable extraction solvents are limited to methanol and acetonitrile, dichloromethane with higher solvent extraction power can be used for MonoTrap.
To obtain a high recovery MonoTrap is an easy-to use media to select the types of extraction solvents.

Standard samples: Limonene, Cineol, β-Linalool, Methylpyrazine,
2,6-dimethylpyrazine, Indole, Camphor, Octanoic acid, Coumarin,
2’-acetonaphthone.
