This book is by far my number one reference book for intitial interpretation of EI data. If you are looking for a book that will help you with chromatography conditions and subsequent interpretation of EI data based on the various classes of compounds, then get this book. I don't think you will be disappointed. If you are looking for a book that delves into instrument theory and trouble shooting, then you will be very disappointed. As the title says this is a "practical guide".
