METHOD OF PHYSICAL-CHEMICAL ANALYSIS OF MATERIALS

摘要

FIELD: quantitative gas chromatographic fractionation of high-boiling components of oil. SUBSTANCE: fractionation of high-boiling components of oil is carried out under low residual pressure ensuring adherence to proportional dependence of partial pressure of analyzed component on its mole fraction in separating fluid. EFFECT: expanded assortment of separating fluids at high temperatures, diminished smearing of chromatographic stripes of components of analyzed material.
