It is not normally recommended that one use high heat to remove the polyimide coating on the capillary. This could create a “void” in the wall coating and produce erroneous results. It is best to use chemicals to remove the polyimide in this case. Be sure to follow good laboratory practices when using hazardous chemicals. 

If you use the MicroSolvCE™ WindowMaker™, please contact Technical Service for an approved technique for removing the polyimide from the Zero EOF or other Controlled Flow capillaries. Call at 1.732.578.1777 or email us.
