Trap Columns
Trapping is a chromatography technique that allows for the concentration or purification of a sample. A trap cartridge is a packed column bed loaded with a material to create desirable conditions for separating the target compound from the rest of the sample matrix. This is accomplished by selecting a packing material that has a strong affinity for the target compound, causing the analyte to be retained in the trap while the rest of the sample matrix flows through, or by selecting a material which has no affinity for the target compound but that binds other unwanted matrix components such as salts, detergents and contaminants.
Which Trap Column Do I Need?
Start with your flow, pressure and connection requirements to narrow down the trap hardware.

Not sure which packing material to choose? Packing material depends on what you are trying to retain, concentrate, purify or remove.
