Applied Analytics OMA-300 Multi-Stream Process Analyzer

Overview

The Applied Analytics OMA-300 is a continuous, multi-stream process analyzer built on diode-array absorbance spectroscopy, engineered to give refineries, gas plants, and chemical facilities real-time visibility into process chemistry that was previously only available through slow, discontinuous laboratory sampling. Using a nova II diode-array spectrophotometer available in UV-Vis (200-800 nm) or SW-NIR (400-1100 nm) configurations, the OMA-300 platform can monitor up to five different chemical species simultaneously from a single optical measurement, updating every 1-5 seconds. This makes it the flagship platform behind the entire Applied Analytics OMA family, forming the base hardware on which specialized configurations for chlorine, BTX, H2S, moisture, and odorant monitoring are all built.

With fast quotation turnaround and technical support, Seven Star LLC supplies the OMA-300 process analyzer on request to industrial customers across Oman and the wider GCC, with lead time and availability confirmed at quotation. Facilities in the Sultanate of Oman running continuous gas processing, refining, or multi-stream chemical operations can specify the OMA-300 with confidence that installation, commissioning, and after-sales technical support are handled by a regionally established distributor rather than a remote overseas reseller.

Measurement Principle

The Applied Analytics OMA-300 operates on the Beer-Lambert law of absorbance spectroscopy: light from a pulsed xenon lamp with an average 5-year service life is transmitted through the sample and captured by the nova II diode-array spectrophotometer, which resolves the full absorbance spectrum across the selected wavelength range in a single pass. Because the diode array captures the entire spectrum simultaneously rather than scanning wavelength by wavelength, the OMA-300 delivers a complete chemical fingerprint of the sample every 1-5 seconds, and proprietary chemometric algorithms mathematically de-convolute the overlapping absorbance signatures of up to five target analytes from that single spectrum.

This all-optical approach carries real operational consequences for plant reliability: there are no moving parts in the optical path, no consumable reagents, and no physical contact between the electronics and the process fluid when the fiber-optic sample interface option is used. Zero drift is held to within ±0.1% after a one-hour warm-up period, meaning the analyzer holds calibration through long unattended run periods that are typical of continuous process units. The result is a measurement technology that avoids the pressure drop, sample degradation, and contamination risk associated with wet-chemistry analyzers or extractive GC systems.

Engineering Design of the Applied Analytics OMA-300

The Applied Analytics OMA-300 is available in three enclosure formats to match the installation environment: a wall-mounted indoor/outdoor enclosure rated for ATEX and Class I Division 1/2 hazardous areas, a portable suitcase enclosure for temporary or multi-point survey work, and a 19-inch rackmount chassis for control-room or analyzer-shelter integration. Explosion-proof variants are available in both purged (Type Z, Eexp) and cast-aluminum flameproof (Eexd) configurations, allowing the same core optical platform to be specified across a wide range of hazardous-area classifications without redesigning the measurement itself.

Electrically, the OMA-300 operates from universal 85-264 VAC, 47-63 Hz power at a modest 45 watts, simplifying power planning across sites with varying grid quality. Standard output is one galvanically isolated 4-20 mA analog signal per measured analyte, with optional Modbus TCP/IP, RS-232, RS-485, Fieldbus, Profibus, and HART protocols available for full integration into a plant DCS or SCADA historian. The analyzer’s ECLIPSE software platform runs on an onboard touch-screen interface, giving operators direct access to live spectra, calibration status, and diagnostic trending without needing a separate engineering workstation.

Key Features

The Applied Analytics OMA-300 platform combines optical robustness with process-grade flexibility, and its core features include the following:

• Simultaneous measurement of up to five chemical species from a single continuous optical scan, eliminating the need for multiple discrete analyzers.
• Selectable UV-Vis (200-800 nm) or SW-NIR (400-1100 nm) diode-array detector configurations to match the target application’s absorbance region.
• Response time of just 1-5 seconds, giving operators near-real-time visibility into process composition changes.
• A pulsed xenon light source rated for approximately five years of continuous service, minimizing lamp-replacement downtime.
• Zero drift held to within ±0.1% after warm-up, supporting long unattended operation between recalibrations.
• ATEX and Class I Division 1/2 certified enclosure options, including purged (Eexp) and flameproof (Eexd) explosion-proof variants for hazardous process areas.
• Flexible communications including isolated 4-20 mA analog outputs plus optional Modbus TCP/IP, RS-232, RS-485, Profibus, Fieldbus, and HART for DCS integration.
• A totally solid-state optical design with no moving parts in the measurement path, reducing mechanical maintenance and unplanned downtime.

Industrial Applications

The Applied Analytics OMA-300 is deployed across oil refining, natural gas processing, sulfur recovery units, petrochemical production, and offshore platforms wherever continuous multi-component monitoring replaces slower manual sampling or extractive gas chromatography. In Oman’s refining and gas processing corridor, and across the industrial zones of the wider GCC, the platform is used to track process gas and liquid streams in real time, supporting tighter process control, faster response to upset conditions, and compliance with environmental and product-quality reporting requirements. The Applied Analytics OMA-300 multi-stream capability also suits facilities that need to monitor several sample points from a shared analyzer house rather than installing a dedicated unit at every location.

With engineering support in Muscat, Seven Star LLC supplies the OMA-300 to petrochemical complexes, gas processing trains, and industrial utilities throughout Oman and the GCC, including facilities operating in and around the Sohar and Salalah economic zones where continuous process analytics support both operational efficiency and export-quality assurance. Regional engineering teams benefit from local access to spare parts, calibration gases, and application support rather than depending solely on manufacturer support from overseas.
