Ind. J. Pharma. Sci. 72(5), 629-632 (2010). TLC of almotriptan malate on silica gel aluminum foil with butanol - acetic acid - water 3:1:1. Quantitative determination by densitometry in absorbance mode at 300 nm. The calibration curve was linear over the range of 100-700 ng/band for almotriptan malate. The method was successfully applied to the analysis of drug in a pharmaceutical form. 

Anal. Biochem. 149, 480-483 (1985). Description of a simple visualization method for sulfolipids on TLC plate, based upon formation of complex between anionic sulfolipid and blue cationic compounds by spraying with an acidic solution of azure A. Detection limit 0.5 nmole of sulfolipids without interference from other lipids. Visualization of sulfolipids as clear dark blue bands on a light blue background after the unbound dye washed out by brief soaking in methanol.

Ein neues Verfahren zum Nachweis von Substanzen in der Dünnschichtchromatographie. I. Nachweis von Flavoniden. Microwave vaporizing-technique of substances on thin-layer chromatogramms. I. Detection of flavonoids. (German). Deutsche Apotheker Zeitung 129, 2178-2179 (1989). New method for the detection of substances on thin-layer chromatogramms. The procedure consists in the vaporizing of the reagent using a microwave-oven. The advantage of the method is illustrated by the flavonoid detection TLC of flavonoids on silica with ethyl acetate - formic acid - water 8:1:1.

J. Planar Chromatogr. 3, 247-250 (1990). TLC of tryptophan on cellulose with 1-butanol - acetic acid - water 4:1:5. Detection by overpressure derivatization (OPD), which is carried out by pressing an absorbent polymeric pad (prewetted with derivatization reagent) on the TLC plate. Relative standard deviations obtained showed that OPD was more reproducible than spraying. Quantification by densitometry (absorbance at 420 and 288 nm after derivatization).

J. West China Univ. Med. Sci. (Huaxi Yaoxue Zazhi) 8, 70 - 73 (1994). Use of a new stable fluorescent reagent CGE(N), for the fluorimetric detection of p-amino-salicylic acid in tablets on silica with petrol ether - chloroform - ethyl acetate 5:3:2. Quantification by densitometry at 277 nm. Detection limit 0.38 µg.

Anal. Biochem. 271, 114-116 (1999). TLC of 10 to 20 (l of the assay mixture containing the SYBR Green II-bound reaction products AMP and ADP on silica with dioxane - NH3 - water 6:1:4. The resulting fluorescence image was directly scanned and quantitated.

J. Planar Chromatogr. 19, 252-254 (2006). TLC of 22 amino acids on silica gel with n-propanol - water 7:3. Detection by spraying with 0.25 % 2,3-dichloro-1,4-naphthoquinone in ethanol, followed by drying in the air at room temperature and heating in an oven at 110 °C for 10 min. After cooling spraying with 0.4 % isatin in ethanol. Visual detection of spot colors (varying from yellow, to orange, pink, purple, and gray). Detection limits were determined visually and ranged from 0.01 µg (cystine and arginine) to 0.30 µg (isoleucine, phenylalanine, methionine, aspartic acid, and glycine).

J. Planar Chromatogr. 26, 202-208 (2013). HPTLC of egg yolk lipid fractions on silica gel with hexane - diethyl ether - formic acid 40:10:1. Detection by srpaying with 10 % copper(II) sulfate in 8 % phosphoric acid. Quantitation by scanning with a flatbed scanner and a gel analysis software. Intermediate/interday/intra-day precision was below 10 % CV (n=6).
