A method for the determination of 2,4,6-trichloroanisole (TCA), other haloanisoles and halophenols in water was optimised by using headspace solid-phase micro-extraction (SPME) and gas chromatography with mass spectrometric detection. The optimised method uses...
A sol-gel chemistry-based polymer coating approach was developed for the preparation of a novel polysiloxane-coated silica stationary phase for capillary liquid chromatography. SE-30, a commercial polysiloxane stationary phase used in gas chromatography, was incorporated into the properly...
The retention behaviour of estradiol derivatives has been studied by HPLC on polar chemically bonded stationary phases: C 3 CN, DIOL and C 3 NH 2 , commercially available columns. The mobile phases used were: methanol-water and acetonitrile-water in various proportions. Reversed-phase...
Comparative determinations of various phenothiazine derivatives in blood and urine samples were carried out using HPLC in reversed-phase mode and non-aqueous capillary electrophoresis (NACE). The examined samples of biological fluids originated from six forensic cases concerning poisonings with...
A rapid and specific reversed-phase high performance liquid chromatography (RP-HPLC) method for the determination of palmatine in rabbit plasma has been developed and validated. The chromatographic separation was performed on a C 18 column at 40 °C. The mobile phase, delivered at 1.0 mL min −1...
A straightforward method based on GC-MS was developed to determine the booster biocide dichlofluanid and its metabolite DMSA in sediment and water. Special attention was paid to conservation of samples, conversion of dichlofluanid to DMSA during analysis and the effect dichlofluanid-containing...
A simple reversed-phase HPLC method has been developed for determination of flurbiprofen in rat plasma, excised skin extract, and transdermal patch formulations. The mobile phase was methanol–1% (v/v) phosphoric acid in water, 80:20 (v/v), at a flow rate of 0.5 mL min -1 ; ibuprofen was used as...
