摘要：
A simple technique was proposed for improving detection sensitivity in capillary electrophoresis by the chemical etching of the interior surface of a fused-silica capillary in the detection region. This technique was applied to the electrophoresis of proteins. The sensitivity was found to increase, on the average, by a factor of 4 to 5 after etching a 75-μm i.d. capillary with an HF solution for 7 min.
