The Agilent 1100 HPLC system features high stability, powerful electronics, and unmatched sensitivity, to name just a few of its features. The system is easy to use and represents a cost-effective solution for your laboratory. Variable Wavelength Detector. The system is equipped with a variable wavelength detector (VWD) that lowers detection limits through simplified optics for high sensitivity, low baseline drift, and wide linear range. Minimal baseline noise ensures high baseline stability at the lowest detection limits. The VWD offers programmable wavelength switching for sensitivity and selectivity, optimized for elution of any analyte, along with stop-flow wavelength scanning for rapid wavelength optimization. Quaternary Pump. The optimized design of the 1100 Series Quaternary Pump ensures virtually pulsation-free and stable solvent flow, with two precisely servo-controlled floating pistons connected in series. This variable stroke volume design enables pulsation-free solvent delivery and efficient mixing. An electronically activated inlet valve synchronized with the piston stroke prevents gas formation with volatile solvents and is maintenance-free. With high-speed proportional valve and pre-configured vacuum degasser for convenient low-pressure mixing of up to four solvents and maximum flexibility in the choice of solvents. This refurbished system comes with: . Agilent 1100 solvent storage. Agilent 1100 vacuum degasser. Agilent 1100 quaternary pump. Agilent 1100 autosampler. Agilent 1100 variable wavelength detector. Agilent 1100 column oven. Options. This system is also available with Clarity or Chemstation data processing software, which allows you to control the system via a computer.
