To be effective and efficient, analyzing samples requires expertise in:
1. The chemistry that can occur in a sample.
2. Analysis and sample handling methods for a wide variety of problems (the tools-of-the-trade).
3. Accuracy and precision of the method.
4. Proper data analysis and record keeping.
The major stages of an analytical process are described as follows (Figure 1).
The pharmaceutical analysis comprises the procedures necessary to determine the “identity, strength, quality and purity” of such compounds. It also includes the analysis of raw material and intermediates during manufacturing process of drugs.
