Column Coupling Electrophoresis in <strong>Biomedical</strong> Analysis<br />

5. <strong>Applications</strong> of column coupling electrophoresis<br />

The column coupled methods, described in previous sections (3 and 4) concerning the<br />

theory (principles, experimantal arrangement, benefits, limitations) and performance<br />

parameters (LOD, precision, recovery/accuracy, etc.), have been used in many applications.<br />

Capillary (CE) and microchip (MCE) formats were taken in<strong>to</strong> consideration. CE and MCE<br />

determinations of various biologically active compounds in model (spiked samples) as well<br />

as real biological matrices, employing an on-line coupling of the electrophoretic methods<br />

with other electrophoretic or non electrophoretic methods, are listed in Table 2. In this table<br />

we tried <strong>to</strong> emphasize briefly the most important features and characteristics of the<br />

applications of column coupling electrophoresis in capillary as well as in chip arrangement.<br />

This table is further supported by the text where other relevant parameters and explanations<br />

are included for the real bioapplications and proteinic analysis.<br />
