Applied Analytics OMA Chlorine Analyzer

Overview

The Applied Analytics OMA Chlorine Analyzer is a continuous process analyzer engineered to measure chlorine (Cl2) concentration in chlor-alkali and related chemical processes using dispersive UV-Vis absorbance spectrophotometry, isolating chlorine’s distinctive absorption signature from total sample absorbance via the Beer-Lambert law. Unlike wet-chemistry chlorine analyzers that consume reagents and require frequent maintenance, the OMA Chlorine Analyzer measures continuously and can monitor up to four chemical species concurrently, while a fiber-optic sample interface keeps the toxic, corrosive sample fluid physically outside the analyzer’s electronic enclosure.

With regional stock and engineering support in Muscat, Seven Star LLC proudly supplies the OMA Chlorine Analyzer to chlor-alkali and chemical processing facilities across Oman and the wider GCC, backed by manufacturer warranty, calibration support, and locally stocked spares. Chemical producers in the Sultanate of Oman handling chlorine gas or chlorinated intermediates gain a regional partner for safe, compliant installation and ongoing technical support.

Operating Principle

The Applied Analytics OMA Chlorine Analyzer directs light from a pulsed xenon lamp with an approximately five-year average service life through the process sample and captures the full absorbance spectrum across 200-800 nm using a nova II UV-Vis diode-array spectrophotometer. Chlorine’s characteristic UV absorption signature is isolated computationally from the composite spectrum using Beer-Lambert law calculations, allowing the analyzer to report chlorine concentration accurately even when other absorbing species, such as nitrogen trichloride or vanadium compounds in titanium tetrachloride streams, are present in the same sample.

Critically, the OMA Chlorine Analyzer transmits the optical signal to and from the sample point via 600 micron-core fiber-optic cable, typically 1.8 meters in standard length, which means the sample flow cell can be mounted directly at the process point while the electronics, light source, and detector remain in a separate, safer location. This fiber-optic isolation is a major safety advantage for a toxic, corrosive gas like chlorine, removing the need to route a hazardous sample line into the analyzer’s own enclosure and reducing the consequence of any leak at the measurement point.

Engineering Design of the Applied Analytics OMA Chlorine Analyzer

The Applied Analytics OMA Chlorine Analyzer is built around a flow-cell and fiber-optic sample interface rated for sample pressures up to 206 bar (3000 psi) with the standard flow cell, and an operating temperature range of 0-35°C ambient as standard, extendable to -20 to 55°C for outdoor or extreme-climate installations. The core electronics and light source share the same rugged OMA enclosure family used across the Applied Analytics product line, with ATEX and Class I Division 1/2 hazardous-area variants available for chlor-alkali plant environments.

Power requirements are universal 85-264 VAC at 47-63 Hz, drawing only 45 watts, and the analyzer communicates through isolated 4-20 mA analog outputs with optional Modbus, HART, and RS-485 digital protocols for direct integration into a chlor-alkali plant’s distributed control system. Accuracy across the instrument’s range is rated at ±5 ppm for 0-100 ppm spans, ±2% of full scale or 5 ppm (whichever is larger) for 0-10,000 ppm spans, and ±2% of full scale at 0-100% concentration, giving plant chemists confidence in both trace-level and high-concentration chlorine measurement.

Key Features

The Applied Analytics OMA Chlorine Analyzer platform is engineered specifically around the safety and accuracy demands of continuous chlorine monitoring, and its key features include the following:

• Continuous chlorine (Cl2) measurement using dispersive UV-Vis absorbance spectrophotometry, isolating the Cl2 signature via Beer-Lambert law calculation.
• Simultaneous monitoring of up to four chemical species concurrently from a single optical measurement.
• Fiber-optic sample isolation using 600 micron-core cable, keeping toxic, corrosive sample fluid outside the analyzer’s electronic enclosure.
• Sample pressure rating up to 206 bar (3000 psi) with the standard flow cell, suiting high-pressure chlor-alkali process points.
• Accuracy of ±5 ppm at low ranges and ±2% of full scale at higher concentrations, spanning trace detection through 0-100% measurement.
• Operating temperature range of 0-35°C standard, extendable to -20 to 55°C for demanding outdoor climates.
• A pulsed xenon light source with an average five-year lifespan, minimizing lamp-replacement downtime.
• Isolated 4-20 mA analog outputs plus optional Modbus, HART, and RS-485 connectivity for DCS integration.

Industrial Applications

The Applied Analytics OMA Chlorine Analyzer is deployed across chlor-alkali production, chlorine gas handling, water treatment chlorination, and specialty chemical processes such as titanium tetrachloride and vinyl chloride monomer (VCM) manufacturing, wherever continuous chlorine monitoring is essential for both process control and personnel safety. Chemical processors across Oman and the GCC use this class of analyzer to maintain product quality specification while protecting operators from the corrosion resistance and toxicity risks inherent in chlorine gas handling.

Backed by genuine manufacturer documentation, Seven Star LLC distributes the OMA Chlorine Analyzer to chlor-alkali plants, water treatment operations, and specialty chemical producers throughout Oman and the GCC, including facilities in the Sohar and Salalah industrial and economic zones where chemical manufacturing capacity continues to grow. Regional customers gain access to genuine Applied Analytics hardware together with local calibration support, fiber-optic sample-interface spares, and application engineering, rather than depending solely on an overseas supply chain for a safety-critical chlorine measurement.
