FIELD: chromatography.
SUBSTANCE: specific area of silica surface reaches 300,2/g, porosity - up to 1,1 cm3/g, average pores diameter - 12,0-16,0 nm. For separating and property detection couples of substances and carrier gas are let through chromatography column, filled with silica powder, which is precipitated from hydrothermal solution, with receipt at output of column of sequence of special components, recorded in form of peaks. Absorbent, received on basis of silica, precipitated from hydro-thermal solution, in several cases has better separating ability then traditional absorbents.
EFFECT: higher efficiency.
