Interlab from Moscow has developed and launched the production of domestic cathodes for gas chromatograph-mass spectrometers, which were previously purchased abroad. The devices are used in medicine, science, and various industries such as chemical, food, and pharmaceutical.
Each gas chromatograph-mass spectrometer has two cathodes installed, which serve as sources of electrons for ionizing the substances being analyzed. Filaments are a consumable. They have a lifespan of up to one year and require replacement. Without regular cathode supplies, the devices could fail, which would entail significant replacement costs.
Interlab specialists carried out reverse engineering of the cathodes, selected the necessary materials, determined the optimal shape, and conducted tests on existing devices. In 2025, the company began producing cathodes, which will allow users to abandon the import of these components. Product deliveries have already begun for Russian customers.
