MonoTrap is a hybrid novel adsorbent that combines large surface area and properties of silica gel, activated carbon, and ODS. Utilizing the surface of porous silica, it can be used as a tool that makes use of the large surface area and the adsorbent effect caused by the inclusion of activated carbon for high collection efficiency and for short time and sensitive analysis. MonoTrap DCC18 (with activated carbon) was used to analyze VOCs in new vehicles. Activated carbon is effective in collecting polar and low boiling components. It is also easy to collect by simply placing a small collection material inside the car room. Capture concentration can also be used as usual, and simple and stress-free enrichment analysis can be performed.
