Abstract
In this paper, a new type of high performance packed column, the submicroparticle packed column (SPPC), has been proposed. SPPC has the advantages of a microparticle packed column, high efficiency and high analytical speed, and a classical packed column, high column capacity, low cost, and easy operation. In some respects, its properties are similar to that of a capillary, which can analyze high boiling point components or wide boiling range samples at a relatively low column temperature. The height equivalent to an effective plate can be as low as 0.155 mm, and the plate number per second is 95. Moreover, the extra-column effect of the chromatographic system and its diminutiveness and the influences on column efficiency (such as average carrier gas velocity, make-up gas flow, and temperature) are also discussed in detail. SPPC is suitable for fast and trace analysis in many fields.
