Study Notes
Introduction to Pharmaceutical Analysis
- Response signal reflects sample's analytical characteristics.
- Internal standard method involves adding a reference material directly to the sample for comparison within the same spectral plane.
Specification
- Defines acceptance criteria for materials in pharmaceutical analysis.
- Includes tests, references to analytical procedures, and numerical limits or ranges for materials.
Signal Generation
- Involves an energy source, typically light (electromagnetic radiation).
- The sample interacts with the energy stimulus to produce an analytical signal.
- The signal indicates both the presence and concentration of the analyte.
Read-Out Device
- Converts electrical signals into a useable format for analysis.
- Utilizes slope-intercept form for linear least squares to establish the relationship between signal and analyte concentration.
