摘要：
It has been demonstrated that there is no significant difference between the maximum peak capacity and analysis time at the same peak capacity in constant pressure (isobaric) and constant flow (isorheic) modes of temperature programmed GC. In view of that, the choice between the two pneumatic modes should be based on considerations other than the speed-separation performance of the column. (C) 1999 Elsevier Science B.V.
