SPECTROPHOTOMETRIC METHOD OF STANDARD CURVE PREPARATION AND CALCULATION FOR METRONIDAZOLE.

Abstract

Standard curve preparation is the very basic need in field of Formulation or Research with a drug or unknown substance before starting the further calculation for a proposed work. This work is done because most of the students are calculating the values of slope, intercept directly from the software and find manual calculation a tedious job. Also the improper way to handle the glassware and some minor negligence in plotting the graph can differ the results. Many of the students that are first time preparing the standard curve faces many problems basically in searching a correct methodology and has certain queries in regard with the preparation of the standard curve like
