Operational Theory
1.0Introduction
The Teledyne Photometric Analyzer uses the ultraviolet (UV) absorp- tion principle to detect and continuously measure a component of interest in a sample stream. The analyzer consists of a single sample cell, chopped beam, folded optics,
1.1Method of Analysis
The following description shows the course of optical energy in the analyzer. The optical energy is emitted from a source lamp in the source module, passed through the sample cell, and received by the sensor, which converts the optical energy to pulses of electrical energy. These pulses of electrical energy are processed further in the detector module.
The result is separate pulses that are compared in the control unit to reveal the measurable difference between optical absorption of the sample at a selected wavelength (determined by the measuring optical filter) and a zero- absorption condition (set by the reference optical filter). The magnitude of that difference represents the concentration of the component of interest in the sample.
