ISBN: 9789388991094

960 pages

## Description

This Indian adapted edition is restructured, offering new and updated material and focuses on more in-depth coverage of the principles and techniques of instrumental analysis. It includes two new chapters dedicated to Mass Spectroscopy and Thermal Methods of Analysis. Chapters on Extraction Methods, Spectrochemical, Atomic Spectrometric Methods, and Liquid Chromatography and Electrophoresis have been completely updated with current developments. The content has also been reorganized to align it better with the curriculum requirements. New pedagogical features introduced are Spreadsheet Problems,
