(Degradation of alkylphenolethoxilates in detergents. Identification by IR spectroscopy and TLC.) Fresenius Z Anal Chem. 322, 42-46 (1985). Isolation and study of biochemical degradation products of nonylphenol ethoxylate containing detergents in river water by TLC on silica with chloroform - methanol 6:1. Detection of nonylphenol acetic acid and nonylphenol-ethoxy-carbonic acids with Rhodamin B and Dragendorff reagent.

InCom-Sonderband 75-90 (1997). HPTLC of 32 pesticides and herbicides on (extra thin) silica gel layers using an universal gradient by means of an AMD-System. Detection by densitometry at 220 nm. On-line coupling of HPLC and HPTLC.

CBS 83, 6-7 (1999). HPTLC-AMD of PAHs in liver and lung of animals exposed to contaminated soil on RP-18 with a 14-step gradient from acetonitrile to methanol - water 9:1. Quantification by fluorescence measurement at 313/>400 nm and 254/>400 nm, respectively. Strict linearity (r2 > 0.99 on 5 measuring points) was proven. Coefficient of variation was found to be < 5 %, and recoveries between 55 and 70 % were given. Limits of detection was determined to be 0.2 to 2 ng/g sample.

J. Chromatogr. A 754, 367-395 (1996). A review with 226 references on the analysis of the title compound by using GC, HPLC, TLC, GS-MS, etc. Discussion also of the enantiomer and diastereomer separation.

J. Chromatogr. A 1218 (19), 2745-2753 (2011). HPTLC of sucralose in waste water on silica gel with isopropyl acetate – methanol – water 15:3:1. The developing time was 15 min. Detection with p-aminobenzoic acid reagent. Quantification by absorbance measurement at 400 nm. The limit of quantification was 100 ng/L at a recovery rate of 80 % and the extraction of a 0.5 L water sample. An interlaboratory trial in 2008 showed good agreement of the sucralose content determined in four water samples by HPTLC and other methods (HPLC–MS/MS or HPLC–TOF-MS). The good accuracy and high sample throughput capacity proved HPTLC as a well suited method for quantification of sucralose in various aqueous matrices.

AnaI. Letters 20, 235-257 (1987). One- and two-dimensional TLC of azo dyes of phenolic compounds in water and grain on silica with chloroform acetone 9:1 or benzene - di-n-propylamine 4:1 for 1-D TLC, and with the two solvent mixtures for 2-D TLC. Assessment by comparison of the spots with standards. Detection limit 0.005-0.2 mg.

Proc. 9th Internat. Symp. Instr. Chromatogr., Interlaken, April 9.-11., 123-128 (1997). In preparation of a German standard procedure (DIN 38407, part 7) in 1994 an interlaboratory test was performed concerning the qualitative and quantitative determination of PAH in potable water. The evaluation of this interlaboratory test with 12 participating laboratories has demonstrated the efficiency, the reproducibility, the repeatability, and the accuracy of modern quantitative HPTLC in environmental trace analysis.
