PRECISION AND CONFIDENCE LEVEL OF CHANGES IN MEASUREMENTS OF GAS ANALYTICAL COMPLEXES BY MEANS OF APPLYING INERT COVERS ON GAS TRACT ELEMENTS
(pp. 4-13)

Abstract. The relevance of using inert (barrier) nanocoatings for protection (passivation) of parts made of stainless steel has been considered. Such coatings ensure solving problems related to the precision and accuracy of the assay and quality testing of substances with the minimum content of active compounds in a sample, lack of stability in the content of active compounds in a sample over time, inability to treat large amounts of samples without repeated calibration. The findings of the research into the new inert SilcoPateks coating applied by plasma assisted chemical vapor deposition (PACVD process) have been presented. Such coating is used for protection against chemically active substances capable of absorbing and interacting with metals, of changing the sample composition, for countering sulfide and other corrosion. We present a comparative analysis of the SilcoPateks coating with its close analogues – SilcoNert® and DurSan® coatings developed by the world’s leading companies – the Restek Co. and SilkoTek Co. (USA). The SilcoPateks coating is widely used in the domestic equipment for chromatography, mass spectrometry, in ultraviolet fluorescent and other analyzers of substances, in samplers for storage, for transportation, testing and research of samples of substances, for stainless fixtures (valves, faucets), fittings and manometers, for sampling stands, air conditioning systems, calibration panels, coolers for cooling samples, water-oil traps (filters) and other items.

Keywords: measurement accuracy, chromatographic measurements, inert coating, barrier nanocoating, sulfinert coating, sulfinert passivation, plasma assisted chemical vapor deposition, PACVD.
