FEATURES AND APPLICATIONS Rosemount Analytical offers a cost-effective, pre- engineered Continuous Emissions Monitoring (CEMS) package for those applications where up to five gases and opacity when required, must be monitored for regulatory compliance. The GMP 1000M CEMS package provides field-proven Rosemount Analytical analyzer technologies coupled with the most ruggedly constructed and dependable sample extraction and conditioning systems in the industry. The GMP 1000M package is backed by the SINGLE SOURCE capability of Rosemount Analytical which includes comprehensive CEMS support services. These optional services can include installation supervision, startup, certification testing, in-house training and on-going maintenance contracts. At the heart of the GMP 1000M is Rosemount Analytical's NGA 2000 MLT, an instrument which brings together over 40 years of analyzer development and application expertise. The MLT uniquely blends the latest sensors, digital signal processing and software technologies to satisfy the most demanding analysis requirement. The MLT continuously measures up to five components in a single analyzer using a combination of non-dispersive infrared (NDIR), ultraviolet (UV), and/or visible (VIS) spectroscopy and electochemical or paramagnetic oxygen sensors. In addition, utilizing the MLT as the interface for a flame ionization (FID) analyzer module for total hydrocarbon measurements and/or a chemiluminescence (CLD) analyzer module for NOx measurements allows the GMP 1000M to monitor many components. The MLT's capability to selectively measure multiple components in a compact enclosure is achieved by the use of a unique dual optical bench design. Depending on the application, any two combinations of NDIR/UV or VIS channels can be combined on a single chopper motor/dual source assembly. Other application-dependent options include a wide range of sample cell materials optical filters and solid state detectors. The NDIR micro-flow detector consists of two chambers (measurement and reference) with an interconnected path in which an ultra low flow filament sensor is mounted. During operation, a pulsating flow occurs between the two chambers which is dependent upon sample gas absorption, modulation by the chopper motor and the fill gas of the detector chambers. The gas flow/sensor output is proportional to the measured gas concentration. The MLT contains a unique eddy current drive chopper motor and source assembly. This design incorporates on board intelligence to provide continuous self-test diagnostics. The brushless motor, long-life bearings, and ultra high rotation speed (120 Hz) ensures long-term reliability, stability, and immunity from power and frequency variations. Incorporated into the chopper wheel assembly is the patented Proof-Peak automatic detector signal compensation feature. This unique feature, operating at 30 times per second, continuously adjusts the detector signal. In addition to providing long term stability, accuracy, and drift free operation this feature facilitates very fast warm-up. Measuring in the VIS/UV region avoids cross interferences which might occur using IR measurements for some gas mixtures and background components, offering the opportunity for enhanced selectivity and sensitivity. The determination of oxygen is based on measurement of the magnetic susceptibility of the sample gas. Oxygen is strongly paramagnetic, while other common gases are weakly diamagnetic. The detector used in the MLT is compact, has fast response and a wide dynamic range. The long-life cell is corrosion-resistant, heated and may be easily cleaned as it has rugged self-tensioning suspension and uses a welded "non-glued" construction. When sample gas is passed over a selective gas diffusion membrane, the oxygen present diffuses into an electrolyte. The oxygen is absorbed and is reduced to water. Lead oxide is developed at the anode. Electrons generated at the anode flow to the cathode of the cell producing a current that is proportional to the oxygen concentration. The principle offers a cost-effective analysis with negligible interference, ease of maintenance and immunity from vibration. The NGA 2000 CLD uses the chemiluminescence method of detection for NOx. First, all NOx is reduced to NO, then ozone, which is internally generated and is reacted with the NO to form nitrogen dioxide in an electronically excited state. The excited molecule immediately reverts to the ground state emitting photons (essentially red light). The light is measured by a photodiode. The intensity of the chemiluminescence is directly proportional to the NOx concentration. The NGA 2000 CLD has user-selectable full-scale ranges from 0 - 10.0 ppm to 0 - 10,000 ppm. The NGA 2000 FID uses the flame ionization method of detection. The sensor is a burner in which a regulated flow of sample gas passes through a flame sustained by regulated flows of fuel gas and air. Within the flame, the hydrocarbon sample stream undergoes a complex ionization that produces electrons and positive ions which are collected by an electrode causing current to flow through a measuring circuit. The ionization current is proportional to the rate at which carbon atoms enter the burner and is therefore a measure of the concentration of hydrocarbons in the sample. The NGA 2000 FID has user-selectable, full-scale ranges from 0 - 1.0 ppm to 0 - 10%. The OPM 20001 Opacity/Dust Density Transmitter meets EPA 40 CFR, Part 60, Appendix B Performance Specifications. The HART® protocol allows operators to interface with the OMP 2000R from any location where the signal wires terminate and permits single-person calibration. It is the only opacity monitor on the market to utilize a single source, single detector, double pass principle of measurement with no moving parts. Measurement ranges are field adjustable. The Model SP 110A Gas Sampling Probe extracts a representative sample from a gas stream for analysis. The probe's external filter reduces particulate in the sample, eliminating blockage of the heated sample line. An optional backpurge feature is designed to rapidly clean the filter and sample tube reducing maintenance. Sample probe problems are typically caused by corrosive condensate. The SP 110A probe and sample line are heated, maintaining an elevated sample temperature to prevent condensation. The SP 110A Gas Sampling Probe can extract a representative sample in temperatures up to 1850°F (1010°C).
