        Purchasing a gas chromatograph for a lab

        A gas chromatograph is a device, used in many spheres, including agriculture, manufacturing and laboratory diagnostics. The devices offer maximum accuracy of test results. In addition, the algorithm of work with such equipment is not complicated and does not require any special training.
        Functional and constructional peculiarities
        The devices are characterized by availability of:

        • a column and a detecting device, due to which the study happens;
        • mixture input system;
        • thermostatic and registering system;
        • devices and tools for selection and loading of components, which need to be isolated.

        The device functions according to the procedure sequence principle. As a result, the analysis of mixtures or separate substances is performed. The gas chromatograph helps to measure the following:

        • calorific efficiency;
        • gross calorific value;
        • methane number;
        • density;
        • Wobbe index;

        Continuous gas chromatograph is actively used in pharmaceutical, food, gas producing and petroleum refining industries.

        Classification

        The equipment differs by the type of columns. These constructional elements are major components. Manufacturers offer:

        1. Open (capillary) columns. They are small in diameter as they consist of small hollow tubes. The use of such tubes decreases the amount of time needed for analysis.
        2. Packed columns, characterized by large diameter, which is filled with absorbing material.

        The second equally important element of the device is the detector. This element performs the study. Depending on the type of detector, the chromatographs can be:

        • flame-photometric and flame ionization;
        • thermoionic;
        • electrochemical;
        • electron-capture;
        • chemiluminescent.

        When choosing a device, focus on the following functional specifications:

        • explosion-proof design;
        • full automation, including the selection of samples, the detection, the data processing and the results transfer in interactive mode;
        • stability of columns;
        • high reliability.

        Focus on high-capacity models. The equipment has to be able to withstand continuous operation.

        Where to find a suitable chromatograph

        In order to buy laboratory equipment meeting your needs, you should consider using BiMedis portal. The intuitive interface allowing setting the search parameters according to certain needs. You can choose the price, the production year, the manufacturing country and the model by yourself.
