Abstract
A method for forming an ultra-thin membrane for use in a chemical analyzer such as a mass spectrometer includes the step of applying a sacrificial blocking layer onto a porous substrate, applying a semi-permeable membrane layer onto the sacrificial blocking layer, and removing the sacrificial blocking layer following cure of the membrane layer. In a preferred version, at least one of the blocking layer and the membrane layer are applied to the porous support by means of spin coating, though other deposition techniques can be employed.
