Abstract
The present invention provides a method for producing a high-quality capillary tube used in an electrophoresis apparatus in a safe and inexpensive manner. A polymer coating on a capillary tube is converted into gas and removed through an oxidative reaction with oxygen radicals resulting from ozone decomposition.
