Pharmaceutical Analysis Nirali Parkashan

Pharmaceutical Analysis Nirali Parkashan

The is is the first edition of a text book in Pharmaceutical Analysis intended for students of Pharmaceutical sciences. This book can serve as an excellent tool for learning pharmaceutical analysis in the undergraduate curriculum prescribed   by the Pharmacy Council of India. The objective of this book is to provide and update knowledge on each to pic of pharmaceutical analysis. The concept of pharmaceutical analysis is complex which needs to be explained well, at the same time the simplicity of concept is to be more focused considering the understanding levels of the undergraduate students. This book is written considering the above thought and concepts on said topics, and have been presented in simple language without compromising qulatily of both language and concepts. The book was written by referring   the concepts   from   renowned  reference   books, latest   articles publish ed in journals   and   from   the own  experience of authors to   provide   updated information.

Pharmaceutical Analysis" is a comprehensive compilation of 5 Units as per the structure designed by Pharmacy council of India which covers the basic principles, technique, applications of various analytical techniques in addition to the recent information about Indian Pharmacopoeia and its monograph. The beauty of the book is that the late st information including the applications of techniques from the data is concise considering the syllabus and number of lectures provided. Thus, students get exposure of exact concept of each topic. Every chapter includes learning objectives of the unit and quest i o n bank containing probable questions, to help students to prepare better for the examinations .

We hope that, the is book would be a handy nutshell for all the student s as well as the teachers teaching the subject of Pharmaceutical Analysis.

We are thankful to Publish er Shri. Jignesh Furia and the entire staff of Nirali Prakashan, specially Mr. Malik Shaikh, Mrs. Manasi Pingle, Mr. Ravindra Walodare an d M s. Chaitali Takale for their co-operation in bringing this book in time.

We shall be grateful to all the teachers and students to provide us valuable suggestions to imp rove the quality of the book in future.
