Used SHIMADZU GC-17A #9378235 for sale

SHIMADZU GC-17A is a Gas Chromatograph (GC) with a Flame Ionization Detector (FID) which is used for the qualitative and quantitative analysis of organic compounds. It is composed of a carrier gas, separation column, injector, detector and data processing unit. The carrier gas is used to transport the sample from the injector to the detector. Various gases can be used including Helium, Hydrogen, and Nitrogen. The separation column is used to separate the individual components of the sample. It is often packed with packing material such as diatomaceous earth, cellulose or graphitized carbon. Temperature is controlled to determine the rate of the separation process. The injector is used to introduce the sample into the carrier gas stream. Non-volatile materials are pre-vaporized and the volatiles are separated and injected in a gaseous form. Injection techniques including on-column injectors, split and splitless injectors and programmer injectors. The detector is used to detect the presence of individual components in the sample. The FID used in GC-17A uses a hydrogen-air flame which converts the individual components of the sample into ionized molecules. These molecules are detected by the detector. The signal from the detector is then amplified and processed by the data processing unit to determine the relative concentrations of the individual components. The instrument is equipped with a range of safety features such as in-built pressure relief valves and safety shut-off valves. It also has adjustable gas flow and temperature controls for precise operation. The calibration curve of the instrument is checked using known sample mixtures and post-run procedures to ensure accurate and reliable results. SHIMADZU GC-17A is a valuable analytical tool which is used to analyze organic compounds in many research and industrial processes. It is suitable for most qualitative and quantitative analyses requiring a gas chromatograph with FID and offers a high degree of accuracy and precision. Its small size makes it ideal for use in laboratories with limited space and its automated features make it easy to use.
