Syringe filters, Minisart® CE

Supplier: Sartorius
Description: Elimination of particles from samples prior to HPLC or other chromatographic analysis is essential in order to maintain the integrity of the chromatography column and to maximise its operating life time. Minisart® syringe filters optimised for sample preparation consist of a polypropylene (PP) housing and membrane components featuring maximum chemical compatibility and minimum extractables to ensure excellent results. Due to the typical range of volumes from less than 1 ml to 100 ml these filters are available in three different diameters with an effective filtration area of 0,12, 1,7 and 4,8 cm².

HPLC columns, SUPELCOSIL™, Suplex™ pKb-100, Supelco®

Supplier: Merck
Description: Suplex pKb-100 columns feature the same bonded phase functionality as SUPELCOSIL LC-ABZ columns. These specially deactivated columns differ in that Suplex pKb-100 is not endcapped, while SUPELCOSIL LC-ABZ is endcapped. The absence of the end-capping reagent results in better performance from Suplex pKb-100 for the strongest basic compounds, while LC-ABZ is preferred when the sample also contains acids and/or zwitterions.

Organic reference standard, Glycerol, analytical standard, Supelco®

Supplier: Merck
Description: Glycerol may be used as a reference standard in the determination of glycerol in samples of beer using gas liquid chromatography (GLC). It is a simple polyol compound, which is obtained as a by-product of soap and bio-diesel industries. It is odourless, colour-less, viscous in nature, and exists as a sweet tasting liquid. It can be derived naturally as well as from petrochemical feedstock.
Glycerol has been used as:

Liquid-liquid extraction, EXtrelut® NT

Supplier: Merck
Description: EXtrelut® NT is a specially processed, inert, wide pore kieselguhr with a high pore volume. It has been used for quite some time within research, for the sample preparation of urine, whole blood, plasma and other biological matrices. Other applications include environmental and residue testing such as analysis of industrial, domestic and wastewater. EXtrelut® NT is supplied either pre-packed in cartridges or as a loose sorbent. EXtrelut® NT simplifies liquid-liquid extraction by replacing separation funnels. Using a single step is more efficient, saves solvent, as well as material and time, in contrast to classic funnel separation. The aqueous sample is simply applied to the EXtrelut® NT sorbent. It distributes itself over the chemically-inert matrix so acting as a stationary phase. Subsequently, elution takes place using organic solvents that are non miscible with water. All the lipophilic substances are extracted from the aqueous into the organic phase.
