HPTLC Insights into Sample Composition

WEBINAR

What Does It Cover?

Thin-Layer Chromatography has been a well-known method for analysis of botanicals and other complex samples since the end of the 1930s. Today’s modern thin-layer chromatography combines the advantage of analytical robustness and high sample throughput with the possibility to use all kind of specific detection methods, e.g. classical UV/Vis/Fluorescence detection, mass spectrometry or effect-directed analysis. This method increases the amount of information for a fast and efficient screening for new compounds and the identification of raw materials especially for samples with a high matrix load such as herbal drugs, cosmetic and food samples.

HPTLC, the most advanced form of Thin-Layer Chromatography, is a powerful yet simple and cost effective tool for testing identity, purity, and strength (content) of botanicals as well as excluding adulteration during quality control. With the publication of general chapters by the United States Pharmacopoeia (USP <203>) and European Pharmacopoeia (Ph.Eur. 2.8.25) HPTLC has officially come into existence as a highly standardized and therefore reproducible analytical technique. The use of high performance plates, suitable instrument and software, a standardized methodology, and validated methods ensures reliable results that are fully compliant with current Good Manufacturing Practice (cGMP). HPTLC fingerprints allow convenient visual comparison of multiple samples even if those originate from different plates (and different laboratories worldwide). Reference images (HPTLC fingerprints of botanical reference materials or other references) can be used to qualify data and pass/fail samples based on similarity or difference.

We will give you an overview about the versatility of HPTLC, applicable to many of your analytical tasks. Don’t miss the chance to extend your knowledge!

This webinar will focus on:

• HPTLC for quality control of botanicals, food, and other complex samples
• Using HPTLC for lead substance identification in combination with on-plate activity screening
• Structure elucidation using direct HPTLC/MS-coupling
