HPTLC separation followed by UV detection of the bitter acid content in various hop samples.
实验方案
The modern thin-layer chromatography (TLC) offers advantages also in the field of cosmetics to quickly and simultaneously analyze samples with densitometric detection.
Thin layer chromatography coupled with mass spectrometry does not require substantial sample preparation. Energy drinks can be applied without dilution directly onto the TLC plate.
Qualitative Thin Layer Chromatography Analysis of Flavonoids and Quantification of Terpene Lactones in Ginkgo Biloba Extracts and Tablets
HPTLC was used to analyze caffeine in coffee. Filtration of coffee through a PTFE syringe filter was the only sample preparation. Quantitation was conducted with a TLC scanner.
