The GA-200-N nitrogen generator (hereinafter referred to as the generator) is a modification of the GA-200 nitrogen generator and is designed primarily to work with a storage tank (receiver) in which a certain "reserve" of nitrogen can be created. Unlike the GA-200, the GA-200-H generator has a built-in pressure monitoring system for nitrogen accumulated in the receiver, which puts the generator into "standby" mode when the maximum pressure value is reached in the receiver, and restarts the generator when the pressure drops below the minimum value. This work allows you to reduce energy consumption and increase the service life of the compressor feeding the generator.

The AP-35 analyzer is a fully automated analytical complex designed for continuous X-ray fluorescence analysis of the chemical composition of slurries and solutions in flow. The instrument has a movable software-controlled measuring head with an X-ray tube and fixed spectrometric channels (up to 8), each of which can be set up for any chemical element (from Ca to U). In operation, up to 15 flow cells are measured by the head according to a preset program. Multi channel capability (up to 15 products to be measured). Compatibility with automation systems for sampling, sample delivery, data handling and presentation, data archiving. Link to factory process control system High expressiveness, high analytical precision, low detection limits, reproducibility High reliability. The principle of operation is based on the excited fluorescence produced by the atoms of the material under analysis through the radiation of an X-ray tube. The fluorescence radiation of a particular chemical element is picked up by the crystal analyzer, and then the radiation at a specific wavelength is detected by an X-ray tube detector. The intensity of the recorded fluorescence radiation of a certain wavelength is directly proportional to the mass fraction of the chemical element in the substance under study.
