Used DIONEX AS 50 #9113304 for sale

DIONEX AS 50 is a laboratory equipment and accessory developed by DIONEX Corporation to perform anion chromatographic, isocratic, and gradient separations. This tool is used in analysis, such as those involving nitrates, sulfates, chlorides, and phosphates, of aqueous and non-polar samples. AS 50 has an anion exchange self cleaning pre-column, built-in vacuum, pressurized eluent generator and an integrated suppressor, which makes it an ideal instrument for anion separations and method development. At the heart of DIONEX AS 50 is a low-dispersion equipment that enables the highest resolution and shortest run times. This system is composed of a high-capacity anion exchange self-cleaning pre-column and a separator that features an organic-solvent-compatible, chemically resistant stationary phase. This unit is designed to provide rapid and reproducible separations with tight peak shapes, and to reduce band spreading by an impressive factor of 8. AS 50 incorporates a low-noise, low-pressure anion suppressor operated with an integrated isocratic eluent. This allows for sample backgrounds that are free of any interferences, making it ideal for non-polar, thermally labile samples. The use of low-noise suppressor coils actually eliminates a great deal of the load noise, providing remarkable peak-to-peak resolution even of low-level components. In addition to the isocratic mode of operation, DIONEX AS 50 also offers a gradient mode of elution. The user has to specify the run time, start, end and gradient length of the run. The user can also choose to set the time or concentration values for the gradient profile. The instrument can be equipped with DIONEX LabCard autosampler for the automation of chromatographic runs. AS 50 comes with an internal vacuum machine that ensures rapid and efficient isocratic elution operation. The patented self-cleaning pre-column reservoir tool provides faster sample loading, which makes it ideal for large-volume samples. The built-in pressure eluent generator enables studies of sample matrices at higher than atmosphere pressures, making it perfect for surveys of high concentrations of anions, biomolecules and large particles. Also, the environment-friendly solvent delivery systems reduce the time of analyses and eliminate potentially hazardous solvent waste. This instrument is compatible with a wide range of analytical anion separations and is an versatile choice for routine laboratories.
