SORBENT FOR GAS CHROMATOGRAPHY Russian patent published in 1999 - IPC

FIELD: sorbents. SUBSTANCE: sorbent comprises a solid carrier and the applied adsorbent - ultradispersed aluminium powder (particle size is 35-240 nm) containing 9-10 wt.-% of oxygen. Sorbent has dinochrome-II as a solid carrier at the following ratio of components, wt.-%: ultradispersed aluminium powder 4.5-5.0 and dinochrome-II - the rest or quartz powder at ratio of components, wt.-%: ultradispersed aluminium powder 1.0-1.2 and quartz powder - the rest. Obtained sorbent exhibits the prolonged high separating capability. Invention can be used in gas chromatography for analysis of alkanes, chloroorganic and aromatic hydrocarbons. EFFECT: enhanced separating effectiveness of the sorbent. 3 cl, 1 tbl
