The operating temps, for cond. I were as follows: Starting temp. 100C. increased 0* N 0- * at a rate of 6.6C/min.j for cond. Ila: 100C for the first 1.8 mins, then in creased at a rate of 6.6C/min; lib: 150C for the first 1.8 mins, then increased at 6.6C/min. Columns coated with SE-52 gave better separations. 0- s O" a Inst. F and M Model 500, modified Det. FID Col. L/d I- l8-m x 0,3-mm; II- 30-m x 0,3-mm Stat. Ph./Conc.
