Analytical instruments have become very important in analysis of so many substances, this book provides detailed steps in analytical procedures for research in Chemical science,Environmental science, Soil science, Mineralogy, Mining science etc. This book is also important for students of analytical chemistry because it shows the importance uses of analytical instruments in analysis of potash and others substances. It would be useful for young students in chemistry to develop there carrier in analytical chemistry branch. This book also discussed the origin and formation of natural potash deposit and their uses it also discussed the basic principles of flame emission spectrometry and atomic absorption spectrometry with their instrumentation.
