Abstract

The carotenoid test for octadecylsiloxaneโ€bonded stationary phases used in RPLC was developed some years ago. Additional experiments have now been performed with varied stationary phases. The effect of the bonding density and of the pore diameter on steric selectivity, polar surface activity and hydrophobicity was determined by using YMC series (J'Sphere and Pack ODSA). The test was also extended to estimate the phase evolution of several classical or hybrid silicas. The high loading phases were also studied, as well as the fused core silicas. The effect of the particle size reduction on the three previous phase properties was investigated in the goal to determine in which way this parameter could also modify the chemical properties of the phases.

A polar-embedded stationary phase (ULTIMA C18) has been investigated for the separation of alpha-, beta-, gamma- and delta-tocopherols by CEC in comparison with commercially available C(18) and C(30) n-alkyl RPs. The behavior of this stationary phase was tested for different mobile phases based on m

## Abstract A quick and safe identification method is shown for plasticizers in PVC using programmedโ€temperature gas chromatography. Plasticizers were identified by their retention index values measured by using normal paraffins. Several stationary phases with quite different polarity are proposed:

An analytical procedure for the large-scale qualitative and quantitative screening of paclitaxel (Taxol ยฎ ) and related neutral taxanes in yew needles has been developed. The needles were selectively extracted with ethanol:water:acetic acid (80:19:1) and the resulting extract was purified from chlor
