Maintenance of laboratory precision instruments
Laboratory equipment is one of the necessary conditions to ensure the completion of experimental teaching and scientific research tasks. The maintenance, maintenance, overhaul and calibration of instruments and equipment are to improve the integrity, utilization rate, efficiency, longevity and guaranteed value of instruments and equipment. Maximum protection.
First: the maintenance and management of instruments and equipment should be based on prevention. Laboratory management personnel should perform routine maintenance on dust, moisture, and corrosion of equipment. Regularly check the laboratory equipment and make timely maintenance work.
Second: the operator should take good care of the equipment, check the integrity of the instrument in the experiment and after the test, and find the problem in time.
Third: the experimenter must master the working principle, performance and structure of various instruments, master the performance and use of various materials, and scientifically store various instruments and equipment. If problems are found to be repaired in time, problems that cannot be solved should be contacted by the manufacturer to consult after-sales service in time to ensure that the instrument does not deteriorate on the original problem.
The experimental instrument HS-20A automatic headspace sampler is a new generation of fully automatic headspace with full automation design, large screen display, beautiful appearance and convenient operation. Injector. The instrument can automatically run up to 20 samples without the need for personnel to be on duty; and has a self-test, fault alarm and prompt, automatic positioning of the sample tray; with an external loading gas adjustment system, without any modification and change to the GC instrument, Headspace injection analysis was performed. The original instrument carrier gas can also be selected; through time programming, functions such as pressurization, sampling, injection, analysis and analysis of backflush cleaning can be automatically realized; the pressure-balanced injection technique can be used for headspace injection with narrow peak shape and good repeatability. Adopting pressure-balanced injection technology, the headspace injection has narrow peak shape and good repeatability; the sample transfer tube and the injection valve have automatic backflushing function, which avoids cross-contamination of different samples; it is more convenient to use for the imported gas chromatograph. Accurate, the instrument is also equipped with a special interface for various imported instruments, which is convenient to connect; for the active substance analysis, an elastic quartz tube can be selected as the sample transfer tube; the injection amount can be adjusted at any time according to the concentration of the sample to be analyzed by the customer; The needle insertion is convenient, and it can be connected to all types of GC inlets at home and abroad. At the same time, it has microcomputer program control. The main functions are as follows:
(1) Method parameter setting, real-time animation display working status, running time;
(2) Sample area, injection valve and sample transfer tube, all three ways are separately heated and temperature controlled;
(3) Set the analysis program and press the run key to complete the entire sample analysis automatically;
(4) With a variety of extended functions: dynamic headspace, purge and trap, low temperature cold traps;
(5) The GC and chromatographic data processing workstations can be started simultaneously, and the device can also be started by a foreign program;
All kinds of instruments purchased by our company can enjoy high-quality after-sales service. The instrument is guaranteed for 12 months from the date of installation and acceptance, and the user can maintain contact with our after-sales service department. Answers or telephone instructions for repairs, professional technical service engineers can be dispatched to the site for troubleshooting within 24-48 hours. If there is an upgrade of the same series of instrument software, our company will provide upgrade service for users free of charge. After the instrument has been used for a period of time, the after-sales service personnel will return to the customer from time to time, ask about the use of the instrument and promptly solve the questions raised by the customer regarding the use and analysis methods of the instrument.
