Shelf life, library

So spectrum interpretation or library searching may be frustrated unless SERS reference spectra are available. Fourth, a practical substrate for routine analysis should be available commercially and have a long shelf life. At this writing, all SERS substrates are prepared by individual labs, usually immediately before use. The world needs a stable, reproducible, and probably disposable SERS substrate in commercial quantities, but so far none of the various substrates...

About two thirds of this book contains new material written by new authors using recent literature. A few topics from the second chapter are deleted. Numerous chapters are totally rewritten with new authorship. At least ten new chapters have been added to make the coverage encyclopedic. I believe that individuals and libraries who have the second edition in their collection should keep that as an independent reference. The material in it is still relevant since the shelf-life of drying technologies is rather long—several decades ...
