J. Liq. Chromatogr. Relat. Technol. 34, 817-828 (2011). HPTLC of diclofenac (1) and ibuprofen (2) in aqueous environmental samples, on cyano phase with dichloromethane - methanol - cyclohexane 19:1:8. Detection by dipping into a Vibrio fisheri bacteria suspension for 3 sec. Then a glass plate was placed on top of the layer and a light-sensitive camera was used to measure the luminescence for 1 to 10 min. Linearity was between 10 and 2000 ng/zone. Limits of detection and quantification were 89 and 129 ng/band for (1), and 20 and 26 ng for (2). The coupling of HPTLC with a luminescent bacteria assay is suitable to determine drugs in aqueous environmental samples.
International Journal of Pharmacy and Pharmaceutical Sciences 3(2), 42-44 (2011).

Quantitative determination by absorbance measurement at 280 nm. Calibration curves were linear (r2 > 0.9970) with respect to peak area in the concentration range of 500-2500 and 500-5000 ng/zone for mirtazepin anf mianserine, respectively. The LOD was 20 and 35 ng/zone for mirtazepin and mianserine, respectively. LOQ was 50 and 85 ng/zone for mirtazepin and mianserine, respectively. The instrumental precision (%RSD; n = 6) was 0.3 and 0.2 %, the repeatability of standards (%RSD; n = 6) was 0.4 and 0.5 % for mirtazepin and mianserine, respectively. The recovery values were found to be 101.2 % for mirtazepin and 99.8 % for mianserine.
