Open tubular columns can be coated internally with the appropriate stationary phase dissolved in a suitable solvent, or, alternatively, with monomeric materials that are subsequently polymerized to form a relatively rigid polymer film on the column walls. There are two basic methods for depositing the stationary phase as a surface film on a capillary column, dynamic coating and static coating, the latter being the most commonly used. [Pg.125]

Dynamic in-tube SPME In this system, we assume the use of a piece of fused silica capillary, internally coated with a thin film of extracting phase (a piece of open tubular capillary gas chromatography (GC) column), or that the capillary is packed with extracting phase dispersed on an inert supporting material (a piece of micro-LC capillary column).
