Solid phase extraction column for sample pretreatment
Presep®-C series
Cartridge type (fillers: silica gel, Florisil, C18, Na2SO4)
The solid-phase extraction used for pretreatment of samples in HPLC, GC, etc. is used frequently instead of conventional liquid-liquid extraction because of advantages such as simple operation and a small volume of solvent used and has been adopted in many official methods relating environmental and food analyses.
Solid phase extraction columns used now consist of cartridge type with both ends closed and syringe type with one end open and a variety of fillers are available.
This time, we have commercialized cartridge columns with both ends closed, Presep®-C series.

1. Features of the cartridge type

1. Applicable to methods of solid phase extraction under increased or reduced pressure
2. Possible to connect several cartridges depending on the types and volumes of fillers

The cartridges are packed with our fillers, which have already been used by many customers, and their qualities are strictly controlled so that they can be used with good reproducibility and reliability.
