Supported Liquid Extraction Columns, Resins & Accessories
Liquid-Liquid extraction (LLE) is a solvent extraction process that separates an analyte by transferring it from one immiscible solvent to another solvent using a separatory funnel. Supported liquid extraction (SLE) is a type of LLE process in which a polar solid media acts as solvent support.
Sample preparation is a vital and time-consuming analysis step and selective sample preparation is essential to exploit the benefits offered by advanced analytical instruments. However, the classical LLE approach can be time-consuming due to the formation of emulsions, poor phase separation, and high-volume solvent consumption.
Our EXtrelut® sorbents and liquid-liquid extraction columns offer more efficient LLE, particularly for sample preparation of aqueous matrices. EXtrelut® NT sorbent simplifies LLE by replacing the separatory funnel. This emulsion-free, single-step process is easy to handle and efficient in solvent consumption and provides material and time savings in comparison to classical funnel separation.
EXtrelut® NT sorbent is utilized in sample preparation for the clinical, diagnostics, food, and beverage industries, in addition to industrial, domestic, and waste-water analysis.

EXtrelut® NT pre-packed columns
We offer three EXtrelut® NT pre-packed columns for the extraction of lipophilic compounds from aqueous solutions based on the sample volume. EXtrelut® NT1 can hold a maximum of 1 mL. The EXtrelut® NT3 and EXtrelut® NT20 can hold up to 3 mL and 20 mL, respectively. In this column, elution is carried out with 2-3 times the sample volume.
EXtrelut® NT bulk packing material & refill packs for SLE
EXtrelut® NT packing material is available for the preparation of large-volume extraction columns. Additionally, we provide EXtrelut® NT refill packs for refilling EXtrelut® NT20 columns.
EXtrelut® NT accessories
We also offer EXtrelut® NT accessories, such as collection tubes with screw caps and cannulae with Luer tip for EXtrelut® NT1 and EXtrelut® NT3 glass columns. Replacement filters are also available for all three EXtrelut® NT pre-packed columns.

Solid phase extraction is a form of digital (on/off) chromatography designed to extract, partition and/ or adsorb one or more components from a liquid phase (sample) onto stationary phase (sorbent or resin). Over the last twenty five years, SPE has become the most powerful technique available for rapid and selective sample preparation (prep) prior to analytical chromatography.
