Conventional sampling media used for this purpose, including SPME, are in the form of sticks or stirrer bars coated in silicon polymer to a thickness of several microns using a process of chemical bonding. The small surface area and thin coatings have disadvantages that include poor Recovery rate and the need for a long sampling time. The newly released MonoTrap™ is a collector developed using a completely new technique. It has a porous silica surface, which extends the surface area, and contains activated carbon, which provides adsorption capacity. The device can therefore be used as a tool for analysis with a high level of sensitivity that enables good Recovery rate within a short time.
