Southern Analytical process analyzers, process monitors and instrumentation for on-line, in-situ and at-line measurement systems, providing continuous single or multicomponent concentration. Techniques employed include: photometric (use of discrete photometers), spectrophotometric (using full spectrum spectrometer), FTIR (FT-IR), FT-NIR, photodiode array (diode array or PDA) UV/VIS (or alternatively single region NIR, UV or VIS), NIR, Mass Spectrometers, tunable diode laser/lasers (TDL) and more... These systems are applied in: polymer melt monitoring for additives; density and other properties; sulfur (sulphur) recovery unit (SRU) tail gas analyzers (air demand and ratio analyzers); Claus, Modified Claus and Superclaus process plant control; amine based tail gas treaters (TGTUs); low-level moisture analyzers; quality of natural gas for moisture, H2S, hydrocarbon dew point (dewpoint); and, gas, liquid, solids composition analysis. Southern Analytical can provide complete integrated analyzers and process control monitors with sampling systems, analyzer enclosures (wall mounting enclosure, shelter or house) and output for plant process control. We offer analyzers for: H2S (hydrogen sulfide), SO2 (sulfur dioxide), COS, CS2, , NO, NO2, NOx, Cl2 (chlorine), chlorine dioxide, NH3, ammonia, BTX, BTEX, benzene, toluene, xylene, aromatics, CO, CO2, color, Saybolt color, Tag Robinson color, APHA color, ASTM color, ASTM 1500 color, Hazen color, Platinum Cobalt color, Sulfur vapor, total sulfur, MEHQ, TBC, H2O, moisture, HRVOC, VOCs, Oxygen (O2) and trace impurities. Our process analyzers have been used for measurements in Refineries, Power Plants, Chemical and Petrochemical plants for process quality, control, as well as continuous emissions monitoring (CEM or CEMs)...

Continuous Emissions Monitor

Model 909 Hot/Wet Single Gas Mass Flow CEM

The AMETEK Western Research® Model 909 is a single gas version of our Model 910 Continuous Emissions Monitor. The analyzer is specifically configured for monitoring stack emissions on a mass rate basis. It measures stack effluent temperature and velocity in addition to pollutant concentrations at stack conditions, enabling mass emission rates to be reported. With the addition of an optional zirconium oxide sensor, the Model 909 is capable of monitoring oxygen.

The Model 909 features a no-moving-parts design for maximum reliability and durability. It is a complete system with
a sample extraction and transport system designed to ensure sample integrity. Housing options for the analyzer include a cabinet or walk-in shelter built to your specifications.

The Model 909 performs all necessary sample gas and calibration gas flow management, and probe and sample line
temperature control. The Model 909 is a full function Continuous Emissions Monitoring System (CEM) which requires the addition of only a sample probe and sample line to be fully operational.
