HPTLC–MS Coupling: New Dimension of HPTLC
2010The direct coupling of TLC/HPTLC with mass spectrometry (MS) is of particular interest because of the later’s high sensitivity, rapid analysis, and ability to aid structural characterization. The conventional ionization method requires heating of the analyte and was suitable only for the analyses of volatile and thermally stable compounds. In contrast,

Stability indicating HPTLC determination of piroxicam
Journal of Pharmaceutical and Biomedical Analysis, 2000A rapid and sensitive HPTLC method was developed and validated for the estimation of Piroxicam (PM). Spectrodensitometric scanning-integration was performed at an absorbance wavelength of 360 nm. To justify the suitability, accuracy and precision of the proposed method, recovery studies were performed at three concentration levels.

Journal of High Resolution Chromatography, 1987
AbstractThe optimized HPTLC of ginsenosides reported in this paper shows that the recommended solvent system has a higher resolution, greater spot capacity, and better reproducibility by comparison with the established ones in the previous literature. Detection and scanning in the fluorescence mode after visualization with 5% sulfuric acid/EtOH by the ...

Journal of Liquid Chromatography & Related Technologies, 2005
Abstract Three simple, rapid, and accurate analytical methods for the determination of citalopram in tablets were developed. The high performance liquid chromatography method was carried out using Waters Nova‐Pak C18 column with a mobile phase composed of methanol–0.067 M phosphate buffer pH 2.00 (55:45, v/v), UV‐VIS detector at 239 nm, and moclobemide
