Developed for demanding processing applications, the Spe Columns Chromabond® C4 is a reversed phase solid phase extraction (SPE) column designed specifically for use in the category of labware and chromatography. This open tubular syringe-shaped column features a C4 phase, a shorter alkyl chain compared to C18 or C8 columns, making it ideal for secondary interactions with polar compounds. With a particle size of 45 μm and a specific surface area of 500 m²/g according to BET, this column offers excellent separation performance. Its pH stability ranges from 2.0 to 8.0, and it comes filled with 500 mg of material. Suitable for use in the analysis of analgesics from blood and compounds that are too strongly retained by C18 or C8 columns, this Spe Columns Chromabond® C4 is an
