Sample Preparation Chromatography

› ‹

We provide you with a portfolio of sample preparation supplies that ensures successful preparation including syringe filters, QuEChERS, spherical silica and polymer SPE cartridges for a broad range of applications.

QuEChERS

Our Supra-d QuEChERS dispersive SPE turns sample preparation into an easy two-step process by using the QuEChERS method. QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) dispersive SPE, is the number one used sample preparation approach in pesticide residue analysis. It eliminates complex liquid extraction methods and extends the range of recovered pesticides. The QuEChERS procedure is fast and easy, improving lab productivity and resulting in fewer errors.

Syringe Filters

Our syringe filters are lab tested and certified to bring you the highest quality available. Our membrane materials are supplied per ISO9001:2008 certified manufacturing practices. In certified clean room conditions, using the latest manufacturing technology to ensure you receive a high quality, consistent product every time.

Supra Clean SPE

Supra-Clean^® (silica based) SPE delivers the recovery, reproducibility, and reliability desired for consistently excellent results.

Supra Poly SPE

Supra-Poly^® (polymer based) SPE delivers the recovery, reproducibility, and reliability desired for consistently excellent results.
