## Abstract A secondβorder nonβlinear partial different equation was derived to describe the dependence of carrier gas pressure in the column on the column distance and the time under temperature programmed conditions. This equation was solved numerically by the modified finite difference method fo

However, the above system has improved sensitivity of less than ng/s. The selectivity is far better than that of an electron capture detector and the response is not totally independent of the number of elements, whereas the response of an electron capture detector is related to the chemical structu
## Abstract The introduction of large sample volumes in capillary gas chromatography is becoming increasingly important in various application areas. Especially in the analysis of very dilute sample (__e.g__., environmental samples) and in coupled LCβGC, large volume sampling is extremely important
