Introduction: When gas analysis and detection, it is often necessary for experimenters to manually sample and analyze. However, due to the different sampling operation methods of the experimenters, it is easy to cause errors in the gas chromatography detection results: for example, the sample peak time is different, and the peak peak shape is not good. Especially when faced with conventional batch analysis and industrial fixed process analysis, manual sampling analysis may have a serious impact on economic production. Auto GS30 gas autosampler can realize automatic sample injection of 30 gas bag samples. The instrument uses a vacuum pump with a controllable flow rate to extract the gas to be measured in the gas bag or syringe, and accurately transfer the sample to the inert quantitative loop in the instrument. The valve group and pipeline switch of the instrument can realize the accurate transfer of quantitative samples. To the gas chromatography column. This equipment provides an efficient and fast solution for the batch and automated detection of volatile organic compounds in the gas. Auto GS30 gas autosampler is used for ambient air detection, industrial waste gas pollution detection, petrochemical industry Features: 1. Automatic sampling, can be processed according to concentration It can realize automatic sampling of more than 30 samples (supporting multiple online expansion digits), and partition processing of samples with different concentrations to avoid cross-contamination of low-concentration samples (ambient air) caused by high-concentration samples (exhaust gas). 2. Anti-cross contamination, low residue Anti-cross-contamination design, the sample pipeline of the instrument can be flushed in both directions: forward flushing is used to flush the sample common pipeline; reverse flushing is used to adjust the sample 1/4 inch ferrule joint and the entire pipeline Pressure and variable-time flushing can minimize the residual and cross-contamination of the entire pipeline. 3. High security and stability All pipelines are made of stainless steel pipes (inert pipelines are optional), and the instrument valve groups are all imported valve groups from abroad to ensure the sealing and safety of the equipment. The pipeline is pumped to a high vacuum by a vacuum pump, so that the sample enters the loop pipeline. After the quantitative loop is filled, the pressure is balanced through the atmosphere to ensure the stable pressure and temperature in the quantitative loop. 4. High accuracy and repeatability The entire instrument pipeline can be heated (room temperature to 130°C) to avoid condensation and precipitation of high-boiling substances on the pipeline, and to achieve the accuracy of sample preparation results. The experimental results are highly repeatable. For samples of total hydrocarbons in the exhaust gas (2mg/L), the repetitive RSD value of a single channel sample is less than 1%, and the repetitive RSD value of a sample of different channels is less than 2%. 5. Optional functions to meet a variety of applications The instrument can be equipped with dual loop pipelines to support simultaneous detection of two channels. Realize the simultaneous acquisition and analysis of dual detectors or control two chromatographic workstations for analysis and detection at the same time. This optional function can realize the one-time analysis of methane and non-methane total hydrocarbons, saving time and analysis cost. The instrument can be mounted with common gas bags (1L, 2L, 3L, etc.) and gas syringe samplers (50mL, 100mL), and the sampling interface and the gas bag or syringe can be manually fixed and sealed. 6. Convenient graphical software The PC-side software can realize automatic operation of sample methods, sequence editing and operation, and can cooperate with gas chromatograph for batch sample collection, sample information entry and database management.
