Aug 20, 2020 · Solid phase extraction (SPE) is a technique designed for rapid, selective sample preparation and purification prior to chromatographic analysis. Using liquid chromatography principles to control selectivity, SPE provides the sample cleanup, recovery, and concentration necessary for accurate quantitative analysis.

Supelco offers chemical research and manufacturing services. In addition to services, it manufactures various products for chemical applications, including accessories, chromatography columns, analytical reagents, syringes, vials, solvents, buffer substances, strips, tests kits, stains and dyes.

Precleaned Vials. Our precleaned, Type 1 borosilicate clear or amber glass vials are washed in non-phosphate detergent, rinsed three times with tap water, and rinsed with ASTM Type-1 organic-free water to remove detergent. Post cleaning, vials are assembled with PTFE/silicone septa and open-top polypropylene caps.

Sample Preparation & Collection Our sample preparation portfolio has been developed to generate representative, reproducible, and homogeneous samples for accurate gas chromatography analysis. Solvents SupraSolv® solvents are developed specially for sample preparation in gas chromatography.

Aug 03, 2021 · Alternatively, if you have already prepared a high-field NMR sample, use one-third of this sample and dilute it further with a low-boiling solvent. Run the GC, as demonstrated by your instructor. Procedures vary at each institution. Figure 2.93: a) GC vial, b) GC-MS instrument, c) Small amount of solid in a GC vial.

A Brief History of Supelco Solid Phase Extraction (SPE) S upelco, the Analytical & Chromatography Division of Sigma-Aldrich, first introduced SPE technology in 1985 under the Supelclean™ brand name.
