Solid Phase Extraction and HPLC for Separation and Analysis - Online SPE System

The Online SPE is a dedicated system exclusively designed for solid phase extraction (SPE) in combination with a powerful analytical KNAUER AZURA HPLC system.

Knauer’s versatile Assistant Module ASM 2.1L with a pump P 4.1S and two switching valves V 2.1S enables an efficient online SPE to concentrate analytes before HPLC analysis. This results in the reduction of sample contamination and analysis time as well as in an increase of analyte yield.

Subsequently, separation and analysis can be achieved with a classical KNAUER AZURA analytical system provided with a column thermostat CT 2.1, P 6.1L LPG pump, and a multiwavelengths detector MWD 2.1L in order to detect up to eight different wavelengths in a simultaneous manner.

This combination permits extremely sensitive determination of low concentrated samples and extracts e.g. bisphenol A (BPA) from water samples.
