## Abstract A quick and safe identification method is shown for plasticizers in PVC using programmedβtemperature gas chromatography. Plasticizers were identified by their retention index values measured by using normal paraffins. Several stationary phases with quite different polarity are proposed:
A procedure is described and evaluated that allows the calculation of linear temperature-programmed retention indices from accurate Kovats retention indices on a given stationary phase and their temperature variation coefficients. The influence of experimental factors such as column film thickness,
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
