The Preparative Chromatography Standard is 5 mg/mL each of Diclofenac sodium salt, Diphenhydramine hydrochloride, and Flavone in DMSO-- this standard mix should be used to confirm the benchmark performance of your preparative or purification system. This particular QC Reference Material is a specially formulated mix that includes a void marker, neutral, acidic, and basic compounds. It can be used with a variety of column chemistries, dimensions, and system hardware.

FAQ
What Is The Shelf Life Of The Waters Gradient Valve Standard? The Waters Gradient Valve Standard listed here has a long shelf life of 36 months. Why May A Gradient System Be Required Within My Lab Setup? Gradient systems allow you to control the flow rate and solvent/buffer changes to improve chromatographic separations. In addition to this, they can be used to sharpen separations and speed column re-equilibration. A four-solvent gradient system is useful for methods development when equipped with methanol, acetonitrile, ammonium acetate buffer, and formic acid solution. Many times, quality control laboratories also use isocratic systems that run a constant-composition premixed mobile phase for rapid separations.
