Summary
The following videos and corresponding narrated PowerPoint presentations are provided for training and education in chemical metrology. Each presentation provides an introduction to different aspects of laboratory operations for the analysis of complex matrix samples. Topics include theory and practice of liquid chromatography, sample extraction and processing, data treatment, and practical aspects of quantitative analysis. Most of the presentations contain a mixture of PowerPoint slides and video segments to illustrate basic principles and procedures for each topic. The same content is provided in the video and PowerPoint formats, and the files are freely downloadable (MP4 video files can be downloaded from within the video player application).
