        As-30g automatic gas sampler

        1、 Brief introduction of the instrument

        As-30g automatic gas sampler is independently developed by Beijing Zhongyi Yusheng Technology Co., Ltd. It is used to automatically inject gas samples stored in air bags or syringes into gas chromatograph or other analytical instruments in batches, and the whole process is automatic. It is mainly used in environmental air detection, petrochemical gas analysis, soil moisture sampling and so on. The operation is simple and convenient. It can be used with all imported and domestic GC and GCMS.

        2、 Instrument features

        1. The user-friendly design of the software interface can quickly and flexibly complete sample position editing and information input, and also realize unattended operation;

        2. Fault alarm and prompt, improve the safety factor of the instrument;

        3. It can be used for automatic injection of conventional gas in batch and the whole process is automatic. It is suitable for gas bag and syringe. It can be connected with all types of GC and GCMS at home and abroad;

        4. Quantitative ring injection can control the injection volume;

        5. Before and after each sample injection, the system automatically cleans the sample pipeline and quantitative ring to effectively reduce cross contamination;

        6. The operation interface is controlled by PC software, and the running progress and parameters are displayed in real time. The data is stable and reliable with good repeatability;

        7. The instrument runs stably, and the stability and service life of various components are considered in the selection of various components, so as to reduce the failure rate of the instrument with better quality, and improve the service life and effective operation time.

        3、 Main technical parameters of the instrument

        1. Temperature control range of valve injection system:

        From room temperature to 220 ℃, the increment is 1 ℃;

        2. Temperature control range of sample transmission pipeline:

        Room temperature ~ 240 ℃ in increments of 1 ℃

        (low voltage power supply is adopted for temperature control of transmission pipeline for operation safety);

        3. Control mode: special working software

        4. Host function: combined with gas chromatography or other analytical instruments, it can automatically complete gas sample injection, sample pipeline cleaning and quantitative ring cleaning.

        Software function: quickly complete the sample position editing, can also add sample information, and automatically save the edited information.

        5. Sample number: 30

        6. Matching sampling device: syringe or air bag

        7. Sampling pipeline: with flow control system.

        8. Volume: 560 * 455 * 490mm L / w / h (30 bits)
