Page 9: Introduction
Chapter 1 Introduction The Thermo Scientific™ 450iQ Hydrogen Sulfide and Sulfur Dioxide Analyzer utilizes pulsed fluorescence technology. The 450iQ analyzer operates on the principle that H S can be converted to . As the SO molecules absorb ultraviolet (UV) light and become excited at one wavelength, the molecules then decay to a lower energy state emitting UV light at a different wavelength.

Specifically, S → SO +hv1 → SO * → SO The sample is drawn into the 450iQ through the SAMPLE bulkhead, as shown in Figure 1–2. From the bulkhead the sample is either shunted to a converter or bypasses the converter and is led straight through to a hydrocarbon kicker.

Chapter 4 Calibration The 450iQ requires initial and periodic calibration according to the procedures described in this chapter. A quality control plan that allows the frequency and number of calibration points to be modified depending on calibration and zero/span check data should be implemented. Such a quality control program is essential to ascertain the accuracy and reliability of the air quality data collected.
