This issue shows how, together with the Universal HPTLC Mix, the right tools for efficient screening in quality control are now available.
CBS 129 is dedicated to colleagues at Chromacim. With their French representative, CAMAG looks back on 20 years of mutual history. Users from industry, as well as from the regulatory and academic sectors, present their work in connection with HPTLC. Three impressive HPTLC applications from French customers are featured in this issue.

Articles covered in this issue include:-

HPTLC routine analysis using complementary developing solvents 
This article describes a new concept for HPTLC. It is based on one solvent of low polarity, one of medium, and one of high polarity to routinely analyze each (complex) sample at three conditions.

Use of TLC, HPTLC, and HPTLC-MS during production and purification processes of active ingredients and their impurities
In this article, the authors demonstrate the strengths of TLC and HPTLC during API manufacturing processes. The conditions for purifications are determined by conventional TLC and the fractions from preparative columns during purifications are monitored by HPTLC and LC.
