Used VARIAN 450-GC #9386533 for sale

VARIAN 450-GC is a gas chromatograph designed to quickly and accurately analyze the composition of a wide range of samples. It can be used to measure multiple compounds simultaneously and often operates in tandem with mass spectrometers to analyze complex samples. 450-GC is equipped with a Siemens 533 FID, a flame ionization detector that facilitates accurate and reliable quantitative measurements. It incorporates a fast-acting temperature programming and control equipment that allows the user to optimize temperature programming for any type of analysis. The split/splitless injector further improves temperature programming by enabling inlet temperature control for more efficient sample introduction. The instrument is equipped with two microprocessor-controlled autosamplers, a column oven, two detectors (FID and thermal conductivity detector), and a vaporizing device. The analyzed sample is deposited in a sample vial. Its temperature is slowly increased until microvolumes of the sample components vaporize and enter a column of carrier gas. The system's column oven is controlled through software, with the temperature ranging from below room temperature up to 400oC. The eluent then passes through the detectors. At the FID, the sample components are oxidized and ionized by a hydrogen and air flame. Electrodes positioned in the flame generate an electrical signal which corresponds to the intensity of the sample components in the flame. The TCD measures the thermal conductivity of the mobile phase, producing a signal which relates to the amount of sample eluted. The output from the detectors is routed to the TIC printer/plotter which plots a graphical representation of the sample components, allowing the user to recognize the components of the sample and compare their relative amounts. VARIAN 450-GC is a reliable, efficient analytical tool. Its unit incorporates a wide range of sophisticated and automated features designed to ensure accurate results. The machine is quick and straightforward to operate, easily configured by the user, and allows rapid sample analysis.
