A novel method for the manufacture of detection windows in polyimide-c
oated fused-silica capillary columns is described. Concentrated fuming
nitric acid at room temperature is utilized for stripping of the coat
ing from a defined section of the capillary. The technique is particul
arly suitable for columns that have a heat sensitive coating on the in
ner wall or for columns that contain an immobilized hydrogel sieving-m
atrix. A column holder for the simultaneous preparation of detection w
indows in an array of more than 100 capillaries is also reported.
