Discovery® DSC-18 Supelco® 96 well plate assembly for high throughput pharmaceutical screening and analysis

SPE Well Plates

Our SPE well plates allow users to process up to 96 samples simultaneously for increased reproducibility and throughput, while maintaining excellent recoveries and increased sensitivity. 96-well plates offer compatibility with multi-channel pipettors and automation, and are available with silica-based and polymeric sorbents.

Online SPE Cartridges

Supel™ Genie Online SPE cartridges offer a sample preparation solution for a seamless workflow from start to finish performed entirely “online” using the LC instrument. Online SPE offers the advantage of eliminating the risk of human error and reduces labor costs by automation of sample preparation.

Centrifuge tube containing pre-determined amount of Supel™ QuE Verde sorbent for dSPE in challenging green matrices.

QuEChERS

The “QuEChERS” (Dispersive SPE, dSPE) method has emerged as a popular sample preparation technique in the area of multi-residue pesticide analysis for food and agricultural products. The QuEChERS technique offers the advantage of higher recoveries, accurate results and high sample throughput.

HybridSPE® DPX tips provides an INTip solution for complete sample preparation.

Dispersive Pipette Extraction (DPX^®) Tips

DPX^® tips provide an INTip solution for complete sample preparation that can be easily automated to achieve extraction in seconds. HybridSPE^® sorbent material is loosely contained within a tip, for selective retention and removal of endogenous phospholipid interferences from biological matrices for LC-MS or LC-MS/MS analysis.

Supelclean™ ENVI™-8 DSK SPE membrane for faster processing of larger sample volumes

Discs

SPE disks are porous glass fiber membranes embedded with modified silica particles that provide fast flow rates for processing large sample volumes. We offer SPE disks that accommodate rapid organic contaminant extraction, making them ideal for the EPA 500 series, including 525.1 and 508.1.

Solid Phase Extraction Accessories

To facilitate sample preparation requirements, we offer a range of accessories including SPE tube components, elution racks, drying attachments, single SPE tube processors, vacuum pump trap kits, disk holders, and vacuum manifolds.

Related Applications

Mass Spectrometry

Mass spectrometry (MS) is an analytical tool used to identify compounds, determine chemical structure, and assess isotopic abundance. In MS, samples are ionized, and the resulting ions are identified based on their mass-to-charge (m/z) ratios.

Gas Chromatography (GC)

Gas chromatography is a common analytic technique used to separate and analyze volatile compounds in the gas phase. GC is applied in many industries for quality control, and to identify and/or quantify compounds in a mixture.

Solid Phase Extraction (SPE)

Solid phase extraction (SPE) is a technique used for rapid, selective sample preparation and purification prior to chromatographic analysis (e.g. HPLC, GC, TLC). SPE is used to exchange sample matrices, concentrate analytes, and remove interferences and contaminants to improve data and protect the analytical column.

QuEChERS Sample Preparation Method

QuEChERS is a ‘Quick, Easy, Cheap, Effective, Rugged and Safe’ sample cleanup method used to prepare food and agricultural samples for pesticides analysis. QuEChERS is based on the Solid Phase Extraction (SPE) technique of sample preparation.

Sample Preparation by Filtration

Filtration separates substances based on physical or chemical properties. Lab samples are routinely filtered before analysis to reduce sample complexity and increase analyte purity. This allows scientists to generate higher quality analytical results.

Sample Purification

A range of purification methods may be used to prepare a sample prior to downstream analysis. Purification reduces sample complexity, removes interferences, and concentrates an analyte before analysis.

Large Molecule HPLC

High performance liquid chromatography (HPLC) can be used to separate and identify different large biomolecules such as protein and peptides in a sample. It is based on the pumping of a sample with a solvent (mobile phase) through a column packed with sorbent material (stationary phase) at a high pressure.

Small Molecule HPLC

Small molecules are ions and compounds of molecular weight typically less than 900 daltons. These compounds can be effectively separated and analyzed by HPLC, UHPLC and LC-MS using mainly silica particles or monolithic stationary phases with a broad range of column chemistries (modifications).
