GRADIENT CHROMATOGRAPH FOR DETERMINATION OF COMPONENT COMPOSITION OF OIL PRODUCTS Russian patent published in 2015 - IPC G01N30/02 

FIELD: physics.

SUBSTANCE: chromatograph comprises chromatographic column with sorbent, batcher, fluid pump for forcing the eluent (solvent), carrier composed of a bundle of 0.05-0.1mm-dia wires passed from the glass flute. Besides, this chromatograph comprises evaporator, drive with speed variator, plasma-ion detector (catharometer), gas (hydrogen) feed mechanism and assemblies for gas and electricity feed to gas preparation panel detector. Detector and temperature control power supply used for supply of thermal control and programming of column temperature, thermostat, thermal regulator, programmer, electronic converter and electronic potentiometer are also incorporated therewith. Note here that chromatograph is equipped with flow divider, collector of oil product components, fluid batcher, evaporation flask, heater-thermostat, refractometric detector, refrigerator, air ejector, filters, gas batcher, gas chromatographic column and oil product discharge line.

EFFECT: increased number of simultaneously analysed characteristics of oil products, decreased number of errors, possibility for definition of mass output of oil product components, higher reliability and simple assembly.
