Acetonitrile

Orochem’s UV/ HPLC grade Acetonitrile is manufactured to the highest specifications to ensure the integrity of your data, maximize sensitivity in your assay and to prolong the life of your equipment. With Orochem’s HPLC Grade Solvents, scientists can expect a consistent, high purity product which is necessary to create reliable Chromatography methods and protocols. Orochem HPLC solvents are lot-to-lot analyzed to meet the high quality specifications for HPLC separations. We control the low levels of peak impurities, residue, water, acidity and alkalinity, the high chemical purity and the UV transmittance; all of which are critical parameters for a successful HPLC application.
