The OMA is a scalable, solid state emissions monitoring technology with the detection limits needed for the EPA regulations of tomorrow.Request a Quote
All OMA models are equivalent in function and performance with identical electronic configurations. The models vary by form factor and materials of construction, each intended for a unique use case.

The OMA-300 is offered in two explosion-proof formats:
Eexp systems are purged and pressurized using a certified air-purging device. This method ensures that toxic/explosive gas is not allowed to accumulate inside the enclosure, and is ideal when instrument air is available.
Eexd systems are contained within certified explosion-proof cast-aluminum enclosures. This method is more practical if the installation is remote or utilities are unreliable.
Modern industrial plants are typically required by law to measure and report the quantities of certain chemicals that they release to the atmosphere. As environmental regulations become increasingly stringent and ubiquitous, more plants worldwide will need adequate process analysis to guarantee compliance.
Government agencies such as the EPA and EEA have rigid criteria for Continuous Emissions Monitoring (CEM) systems. Stipulations include the mandatory monitoring of emissions of SO2, NOX (generic term for nitrogen oxides including NO and NO2), CO, CO2, and O2, as well as strictly regulated reporting of these chemicals’ concentrations.
While reducing emissions is a pressing environmental issue, it typically poses no direct financial benefit for the plant yet requires purchasing and servicing expensive equipment. Clearly, an ideal CEM system provides reliable compliance at minimal cost. The OMA CEMS is a fully integrated powerhouse, monitoring dynamic concentrations of various emitted chemicals with a single system.
While this solution leads its class in multi-component accuracy, it remains cost-effective by virtue of low-maintenance solid state design, competitive pricing, and high scalability for your exact analysis needs. The painless, economical route to environmental compliance and public social responsibility begins as soon as your OMA emissions monitoring solution is installed.
To analyze the chemical composition of the sample, the OMA uses an analysis method known as ultraviolet-visible (UV-Vis) spectroscopy. The system measures absorbance from 200nm to 800nm and quantifies the amount of light absorbed by the sample at each integer wavlength; the OMA plots this raw data to visualize a high-resolution absorbance spectrum.

The OMA uses a long-life xenon light source to transmit a signal through the sample fluid in the flow cell. The signal is carried by fiber optic cables from the analyzer to the flow cell, where the chemical mixture of the sample has unique interactions with the light based on its current composition.

Our proprietary ECLIPSE software processes the raw spectral data to provide real-time concentration readings. The operator can easily navigate between views (trendgraph, spectrum, and more) using intuitive touch-screen navigation. You can also configure alarms, data logging, and outputs. Learn more
Most analyzers draw the process sample directly into the analyzer enclosure for analysis, which is dangerous if the sample fluid is toxic, explosive, or corrosive. The OMA design is unique: we bring the light to the sample, not the other way around. The sample circulates through the external flow cell, which receives the signal via fiber optic cables.

The OMA is built for direct analysis of the hot/wet sample, thus simplifying the scope of the sample system and retaining high sample integrity. From our vast experience in sampling design, we know that applications can be similar but are rarely identical. For this reason, we design and build sample conditioning systems on a project basis, working from the process to the drawing board.
Note: All performance specifications are subject to the assumption that the sample conditioning system and unit installation are approved by Applied Analytics. For any other arrangement, please inquire directly with Sales.
