UNIVERSAL SYSTEM OF CHEMICAL ANALYSIS gas chromatography (GC-USKHA) DEVICE injection valve and detector density of the gas

摘要

1. A universal system for chemical analysis by gas chromatography (GC-USKHA) including sebyaopredelenie concentration with a detector gas density from 100% to 0.0005% with tap-dosing of vials fluoroplastic material 1 / compound 2 at a temperature from 40 ° C to 170 ° C, and gas mixtures in cylinders substance / propane, as well as other objects, and to the evaporator from solutions of liquid and solids, for a basic calibration, for chegoopredelyayut concentration with tap-dispenser and a detector gas density of the vials benzene / hexane mixture at a temperature 90 ° C to 130 ° C and propane from cylinders in a carrier gas of from 100 to 0.01%, and the turn daleepri packed column with dosing to the crane with a flame ionization detector (FID) or thermal conductivity detector (TCD) propan dosed in a carrier gas from cylinders 10% to 0.01%, and a benzene / hexane of the vials at a temperature of from 90 ° C to 130 ° C and the concentration of propane in the carrier gas from the cylinders from 0.000001% to 0.01% and the concentration of benzene / ampoules of hexane at a temperature of from 40 ° C to 90 ° C, the concentration opredelyayutP * V * C = m * R * T / μ, P * V * 1,0 = m * R * T / μ, C = m / m, m = k * S, C = S / S, where: P - the pressure in the dose, V- dose volume, C- conc entratsiya analyte in a sample, m- mass of analyte in a sample, m- dose of 100 mass% of the material, μ - molecular weight substance, R = 8,314 - universal gas constant, T - temperature, maintained at the tap-dispenser, k - calibration coefficient, S - determined by peak area, S- peak area of ​​the 100% substance, after chegoprovodyat base graduirovkupo hexane, benzene and propane using metering crane column and the base NK-1,0 × 0,3-C 80 ÷ fr.0,18 0.25 PID and / or accident and / or feed, carrying out calibration for different substances, for which the concentration is determined with the crane and DPG
