Notes:
Using hold-up time as a measure of the speed of analysis with a given column efficiency, a theory of pneumatic optimization of a column in the fast high pressure drop isothermal and temperature programmed GC is developed. Expression for the hold-up time as a function of column efficiency, carrier gas velocity and film thickness is derived. Also found are the expressions for the minimum hold-up time and optimum gas velocity in a speed-optimized column. These quantities are compared with their counterparts in the efficiency-optimized column.
