Solid-phase extraction (SPE) is a sample preparation technique routinely used in analytical laboratories for the extraction of analytes from a complex matrix. KChrom solid phase extraction (SPE) tubes are offered with extra pure and clean sorbents and high-purity materials to minimize background and help eliminate unwanted interference.
KChrom has also advantage in packaging of tubes; Each box contains sealed foil bags of tubes to improve shelf life and keep unused sorbents dry and fresh.
