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.
