The SD-1 Purification Systems is manufactured by Agilent Technologies. It is the ideal system for chemists and process engineers to achieve better gradient accuracy and reproducibility over an unmatched flow range. A single configuration can handle reconnaissance runs and then scale up to purify a few grams or even hundreds of grams. Standard systems have flow rates from 1 to 200 mL / min and can be easily upgraded to 500 mL / min. Options for purifying complex samples include a 410 autosampler, a 1260 Infinity II variable wavelength detector, and a 440 fraction collector. OpenLAB CDS ChemStation software provides complete control over analytical and preparation-scale workflows.
