D. M. Gabriel, B. M. Milwidsky: Detergent Analysis. A Handbook for Cost-effective Quality Control

Detergent Analysis is a handbook for the industrial laboratory where time and costs are crucial to efficient and economic processing.
The information, which is based on many years practical experience, is presented in a simple and orderly way so that the methods described can be followed easily. The main quality control scheme covers rapid methods that require very little capital outlay; the use of more specialised equipment in rapid routine analysis is also explained. Chapters are included on evaluation and performance tests for new materials, analysis of unknowns, and laboratory apparatus.
This is not only an invaluable reference work for the analyst in industry but also forms an ideal introductory text for the small enterprise requiring an effective and economic system for routine control analysis.
