The present disclosure relates to methods for deposition of gas
chromatography (GC) stationary phases into chromatography columns, for
example gas chromatography columns. A chromatographic medium is dissolved
or suspended in a solvent to form a composition. The composition may be
inserted into a chromatographic column. Alternatively, portions of the
chromatographic column may be exposed or filled with the composition. The
composition is permitted to solidify, and at least a portion of the
solvent is removed by vacuum sublimation.
