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.

Solid-phase extraction for increased productivity: LiChroPLATE® microtiter plates improve the sample throughput and speed of sample preparation. LiChroPLATE® enables solid-phase extraction to be carried out with considerable convenience and flexibility. From sample application with multi-channel pipettors to complete automation of the sample preparation process. Only in this way high sample throughputs can be achieved. LichroP…

Enhanced selectivity for polar analytes: LiChroPLATE® EN microtiter plates for solid-phase extraction shortens sample preparation time up to 75% compared with other polymer phases. By using LiChroPLATE® EN in combination with an 8-channel pipettor, it is possible to extract 96 samples in less than half an hour. EN stands for enhanced selectivity with respect to all polar analytes – whether basic, neutral or acidic. Even for la…

Solid-phase extraction for increased productivity: LiChroPLATE® RP-18 microtiter plates for solid-phase extraction enable ultra-rapid sample preparation with excellent recovery rates and high precision. Up to 96 samples can be processed simultaneously, which means a significant reduction in the time needed for sample preparation and consequent savings on purchasing and disposal costs. The batch-to-batch reproducibility of LiCh…

For direct in-line sample preparation of untreated bio-fluids: LC-integrated sample preparation with LiChrospher® ADS is less expensive, less time consuming and more precise in comparison to conventional off-line sample preparation. LiChrospher® ADS allows the direct extraction and enrichment of hydrophobic, low molecular analytes from untreated samples such as haemolysed blood, plasma, serum, milk, salivary fluid, fermentatio…

SMS 100 Automated Mercury Analyzer.   The SMS 100 is a full function, stand alone, automated mercury analyzer. It employs thermal decomposition, gold amalgamation and cold vapor atomic absorption spectrometry designed for sensitive measurement of mercury in solid samples eliminating the need for elaborate sample preparation. Standardization can be accomplished using aqueous standards. The SMS 100 requires a compu…
