Molecular formula : CAS :
nature : wall-coated capillary column (WCOT) and supporter coated capillary column (SCOT), WCOT fixative is coated in the capillary wall or processed (plus surfactant or silane) in the capillary wall. Because of this easy-loss effect short-lived. SCOT column is the first supporter (more diatomite) adhesion in thick glass wall, then pull into heated capillary bearing the body evenly distributed in the capillary wall, then painted with fixative pose SCOT column. This column improve WCOT column flaw is that the broader application of capillary column.
