Linearity was in the range of 375-900 ng/zone for (1) and (2) and 750-1800 ng/zone for (3). LOD and LOQ for (3) were 1 and 3 ng/zone. Recovery was in the range of 98.3-102.9 % for (1) to (3). Intermediate/interday/intra-day precision was below 2 % (n=6).
J. Planar Chromatogr. 27, 372-376 (2014). For quality control, HPTLC of cefprozil monohydrate on silica gel with ethyl acetate – acetone – methanol – water – glacial acetic acid 15:5:5:3:1. Quantitative determination by absorbance measurement at 280 nm. The hRF value of cefprozil monohydrate was 20. Linearity was between 200 and 5000 ng/zone. The intermediate precision was below 1.5 % (n=3). The LOD and LOQ were 52 and 75 ng/zone, respectively. Recoveries were in the range of 98.7-101.2 %.
J. Planar Chromatogr. 29, 59-65 (2016). HPTLC of methadone in syrup on silica gel (1) or RP-18 (2) with methanol – 25 % ammonia 10:1. Detection by spraying with 1 mL of Dragendorff reagent. Quantitative determination using a flatbed scanner with a resolution of 16 bits. The hRF of methadone was 44 on (1) and 23 on (2). Linearity was in the range from 60 to 1260 ng/zone. The LOD and LOQ were 100 and 200 ng/zone, respectively. A total relative uncertainty of 6.5 % was achieved.
J. Planar Chromatogr. 30, 164-169 (2017). HPTLC of hexyl nicotinate on silica gel with acetone ‒ n-hexane 3:7. Chemical stability analysis was performed in aqua–ethanolic solutions stored in ordinary and quartz flasks heated at 40 °C and exposed to UV radiation at 254 nm. The main products of chemical changes of hexyl nicotinate are the substances with hRf 37 and 68. Preliminary identification of the decomposition products was achieved by GC–MS analysis.
J. Planar Chromatogr. 31, 122-128 (2018). HPTLC of ondansetron with chloroform ‒ methanol ‒ ethyl acetate 7:2:1. Quantitative determination by absorbance measurement at 302 nm. The hRf value for ondansetron was 67. Linearity was in the range of 25-500 ng/zone. The intermediate precision was below 1 % (n=3). The LOD and LOQ were 5 and 15 ng/zone, respectively. Average recovery was 100.3 %. The method allowed the separation of the drug from its different degradation products.
