Page 23: Introduction
Chapter 1 Introduction The Model 80i Hg Analyzer combines proven detection technology, easy to use menu-driven firmware, and advanced diagnostics to offer unsurpassed flexibility and reliability. The Model 80i has the following features: 320 x 240 graphics display ● Menu-driven firmware ●...
Page 24: Principle Of Operation
Hg Continuous Emission Monitoring System (CEMS). Thermo Fisher Scientific’s Mercury Freedom System is comprised of a Hg analyzer (Model 80i), a Hg calibrator (Model 81i), a Hg probe controller (Model 82i), and a Hg probe (Model 83i) along with additional peripheral components, such as a zero air supply, umbilical, and instrument rack.
Page 25: Figure 1-1. Model 80I Flow Schematic
Calibration gas from the Hg calibrator (Model 81i) is plumbed to the zero air and cal gas bulkheads on the rear panel of the Model 80i. The zero or span gas is routed through an internal critical orifice, through either the NO or NC port of Solenoid S4, through the NC port of Solenoid S3 and into the fluorescence chamber.
