Micro-thin layer chromatography is a time- and material-saving analytical method that is also characterized by good reproducibility. Many public pharmacies, PTA schools, universities, and the pharmaceutical industry are already successfully using this technique. In this practical manual, the author publishes detailed micro-TLC regulations for numerous drugs, active substances, and essential oils. The new edition includes an additional 220 substances and drugs. For the first time, it also includes substances from traditional Chinese medicine (TCM). The TLC regulations of the DAC/NRF are presented as micro-TLC regulations, along with the examination regulations for drugs from the Pharm. Eur. Additional practical tips help minimize execution errors. The illustrations correspond to the original plate size and can thus be compared 1:1.
