The optimum flow rate in high temperature capillary column ion chromatography

초록

The optimum flow rates for the nitrate ion were measured experimentally using 1 m x 50 mum i.d. Latex particle coated silica capillary. The Van Deemter curves for nitrate at 75, 110 and 150 degreesC were also obtained. Increasing the column temperature resulted in an increase of the optimum flow rate for the nitrate ion. The theoretically calculated optimum flow rates in 50 mum i.d. open tubular ion chromatography matches fairly well with actual experimental data. (C) 2001 Elsevier Science B.V. All rights reserved.
