MonoTrap is a novel hybrid adsorbent that combines a large surface area with the properties of silica gel, activated carbon and ODS. High collection efficiency is achieved due to the large surface area of the porous silica and the adsorption effect of activated carbon, this makes it possible to perform high-sensitivity analysis in a short time.

In this application, a simple concentration and analysis was made for the aroma components in lavender using MonoTrap carbon-containing (DCC18). By simply placing samples in the vials it was easy to concentrate, analyze and identify the characteristic flavor components, β-Linalool, etc. Due to the large surface area, considerable information was obtained with high sensitivity even with solvent extraction, even when sample loading was large and dilution was a concern.
