Analytical Sample Preparation
Our sample preparation and purification portfolio includes products for solid phase extraction (SPE), QuEChERS, solid phase microextraction (SPME), air monitoring, sample decomposition, purge and trap techniques, flash chromatography, and LPLC. Our comprehensive range features products for clinical, pharmaceutical, environmental sample prep, phospholipid removal, dioxin and PCB sample analysis, and desorption tubes and adsorbent cartridges for active and passive air sampling.
Millipore® Filter Membranes
Millipore® membranes have supported laboratory filtration in academic, pharmaceutical, and industrial sectors since the 1950s. We provide a range of membrane chemistries including MF-Millipore® mixed cellulose esters, Durapore® PVDF, Millipore Express® PLUS polyethersulfone, as well as hydrophilic and hydrophobic PTFE.

Millex® syringe filters are available in sterile and nonsterile formats, offered in many membrane and housing options to enable compatibility with multiple solvents and sample types for applications including HPLC, UHPLC, and dissolution testing.
Products include cartridges, glass tubes, 96-well plates, QuEChERS tubes (dispersive SPE), online SPE, and vacuum manifolds for all of your scientific needs.
Solid phase microextraction (SPME) is a solvent-free sample preparation technique. View our complete offering of SPME products. Our innovative products for SPME include the smart SPME fibers, nitinol-core fibers, and BioSPME.
Quality air monitoring products for the detection and measurement of exposures to gases, vapors and particles in ambient, indoor air and workplace environments. Our range of products include active, passive and whole air sampling devices; air sampling pumps and related accessories.
The purge and trap method is applied for the analysis of volatile organic compounds (VOCs) in aqueous samples by purging the sample with inert gas and transferring volatile analytes to an adsorbent trap in a gas chromatograph (GC).
Our EXtrelut® NT simplifies the liquid-liquid extraction (LLE) by replacing separation funnels. This emulsion-free single-step process is easy to handle and suitable for trace metal analysis, with minimal solvent usage, high batch-to-batch purity, reproducibility, and recovery rate.
