Publications on HPTLC

This white paper focuses on the analytical tasks in the quality control of herbal drugs, preparations, and products.

HPTLC is a highly versatile, reliable and cost-efficient tool for the rapid in-parallel analysis of multiple samples. In this white paper, we present typical applications in food analysis.

This white paper focuses on the steps documentation, derivatization, and densitometric evaluation. In contrast to other chromatographic techniques, HPTLC offers the unique opportunity to visualize and document the chromatographic result by obtaining high-resolution images of the plates. Substances without chromophores or fluorophores can be visualized or made detectable through derivatization. For quantification, either densitograms or image profiles can be used.

This white paper is the first in a series and provides insights into the principles of planar chromatography. It describes the different parameters and their interaction, which are the basis for the technique’s great flexibility.

This white paper focuses on sample application and development, which are the most crucial process steps of HPTLC, building the basis for quality and reproducibility of the analysis.

This white paper focuses on standardization in HPTLC, converting TLC/HPTLC methods into standardized methods, and the concept of comprehensive HPTLC fingerprinting.
