These LpDNPH cartridges are suitable for sampling carbonyls in ambient, indoor, and industrial atmospheres. The derivatives are eluted from the cartridge in acetonitrile and are analysed by HPLC.

Supplier: Merck

ORBO™ sorbent tubes contain two beds of the same selective adsorbent seperated by glass wool or foam, for gas and vapor sampling.

Supplier: Merck

Dual layer SPE tube that contains Na2SO4 (upper layer) and Florisil (magnesium silicate; lower layer) separated and packed with PTFE frits (glass tubes) or PE frits (PP tubes).

Supplier: Merck

Solid phase extraction disks provides faster flow rates and exhibits less clogging than PTFE discs for the extraction of organic contaminants from drinking water samples.

Supplier: Avantor

BAKERBOND spe™ columns are disposable PP columns pre-packed with high capacity sorbents contained between two 20 µm PE frits.

Supplier: Avantor

These glass column processors are specially designed glass vacuum chambers that allow multiple samples to be run simultaneously. The glass chamber allows unobstructed viewing of samples at all times.

Supplier: Avantor

These SPE columns are designed for the clean-up of extracts of hydrocarbons from water.

Supplier: Avantor

Ultra-clean, PP columns with BAKERBOND® HPLC media are engineered to save time, minimise work and final solvent volumes and improve performance. Run times are up to nine times faster than conventional columns. The built-in column guard filter and higher analyte concentration may reduce or eliminate pre-filtration and concentration steps.

Supplier: Avantor

Solid phase extraction, as a sample preparation technique, often requires stationary phases stable in the whole pH range. Styrene-divinylbenzene (SDB) copolymer sorbent can improve the quality of sample preparation.

Supplier: Avantor

This solid phase extraction column is designed for the extraction of PCB’s in oil (dirty samples) in combination with SPE silica gel.

Supplier: Avantor

These SPE columns are designed for the extraction of pesticides from water.

Supplier: Merck

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.

Supplier: Merck

Solid phase extraction vacuum manifolds allow to simultaneously process up to 12 or up to 24 SPE tubes. Precise flow control is provided through each SPE tube by rotating the independent, screw-type valves in the cover, this ensures the packing will not dry out in some tubes while others finish draining.

Supplier: Merck

This Reversed phase Supelclean™ ENVI-18 are suitable for excellent for cleaning, extracting and concentrating pollutants from aqueous environmental sample (drinking, ground, waste water). Also suitable for extracting herbicides, fungicides and pesticides from waste material.

Supplier: Avantor

Discs are pre-assembled for use in preparing aqueous samples for analysis. Laminar configuration provides filtration capacity and inlet characteristics that maximise access of analyte molecules to the micro-particulate sorbent. Disc design resists clogging and ensures high throughput rates even when samples contain solids.

Supplier: Merck

Syringe filters are single-use, membrane-based devices used for the removal of particulate impurities from liquid and gas samples prior to analysis by methods such as HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing. Proper filtration of samples improves the quality and consistency of analytical results and decreases instrument downtime.

Supplier: Merck

Automation compatible filter units are specially designed to provide efficient filtration for dissolution and other automated sample preparation applications.

Supplier: Avantor

These columns feature BAKERBOND® DVB polymer resins, which are the product of ultra-clean polymer microparticle technology. These resin particles have a large surface area, are highly rigid, are stable over pH range 1 to 14, are water-wettable and are not impacted by sorbent drying. These columns are recommended when advanced detection methods are used.
