A “Brush-type” phase with broad applicability for separation of enantiomers: Whelk-O 1 is a reliable chiral HPLC column of high solvent stability and broad applicability. Whelk-O 1 is a “brush-type” phase according to the concept of Pirkle with (3R, 4R)-4-(3,5-dinitrobenzamido)-1,2,3,4-tetrahydrophen-anthren or (3S, 4S)-4-(3,5-dinitrobenzamido)-1,2,3,4-tetrahydrophen-anthren as chiral selector with high enantoselectivity for a…

High recovery sample preparation for drug analysis and screening: LiChrolut® TSC is a selective and efficient solid phase extraction sorbent designed for clean-up of pharmaceutical products and drugs obtained from blood, plasma and urine. LiChrolut® TSC belongs to the family of the so-called “mixed-mode phases”. The combination of a reversed-phase and a cation exchange mechanism gives rise to retention of the analyte on the st…

For reproducible sample preparation: LiChrolut® CN and NH2 are medium polar phases for solid phase extraction, which produces excellent reproducibility of sample preparation. This results a combination of high chemical stability and guaranteed capacity. LiChrolut® CN and NH2 are suitable for both polar and non-polar extractions. These medium polar phases have, in addition to a short-chained propyl-spacer, a polar functional gr…

Highest capacity for solid phase extraction: LiChrolut® EN saves time and money in solid-phase extraction as less time is required for conditioning and drying. In addition, only a little solvent is required for elution of the analytes from the cartridge bed. The reduced quantity of solvent leads to a lower degree of contamination and to an increase in detection sensitivity. This improves the analysis of the relevant extracted…

Using the LiChrolut® extraction unit simplifies solid-phase extraction and makes it more rapid and reliable. The drying attachment speeds up the drying process under controlled conditions. All the individual steps associated with solid-phase extraction can be carried out using the LiChrolut® extraction unit.

Solid-phase extraction with LiChrolut® is a reliable and rapid route to successful sample preparation and the selective extraction of compounds from a complex sample. Three different modified SPE sorbents are available for non-polar solid-phase extraction: LiChrolut® RP-18 endcapped, LiChrolut® RP-18 and LiChrolut® RP-select B. The difference in polarities are clearly described by the adsorption characteristics. This can save…

A unique high performance ion exchange system for solid phase extraction: LiChrolut® tentacle ion exchanger improves the mass transfer and the recoveries in ion exchange solid phase extraction. Small elution volumes, very high chemical stability and very high capacity are also reasons for the superiority of LiChrolut® SCX and SAX. In contrast to conventional ion exchangers, tentacle functional exchange groups do not lie in def…

LiChrolut® Si 60 is a high purity sorbent for solid phase extraction. Highly purified LiChrolut® Si 60 on the basis of non-modified silica with a pore diameter of 6 nm is available for conventional polar extractions.
