“…The efficiency as determined for 2,4-dimethylpentene was 550 theoretical plates per meter. [75][76][77] Early in the 1960s the dynamic silica gel coating method was employed by Perkin-Elmer for the com-mercial preparation of copper capillary adsorption columns. These columns were ca.…”

“…i.d. glass capillary column supplied by Schwartz (10) was utilized with an attached inlet injection and outlet sections of fused silica capillary tubing (uncoated, 20 cm X 0.32 mm i.d,, Quadrex Corp., New Haven, CT). A 1 jitL hexane solution contained about 1 part in 6000 of each of benzene, toluene, ethylbenzene, and xylenes (para, meta), and about 1 part in 25000 of each of n-nonane, ra-decane, and n-undecane was injected with our on-column injector (11).…”

“…Separations of C, to C,, were shown, but resolution was low and the peaks were broad. Mathews et al described a column containing a 0.2 pm porous layer of silica for the separation of C, to C, hydrocarbons [18]. While the peaks were very sharp, the resolution was still low.…”

Abstract. We report a simple method for the preparation of silica PLOT columns using fused silica capillaries. In this method, silica particles were suspended in a methylene chloride/pentane solution containing polymethylhydrosiloxane and passed through the capillary tubing. This caused the silica particles to be dynamically coated on the inner wall of the fused silica capillary. The column was dried and heated, which facilitated the simultaneous deactivation and bonding of a uniform mono-layer of porous silica on the inner wall of the capillary tubing. These columns were used to separate light hydrocarbons, chlorinated hydrocarbons, and aromatic compounds.
