OMA-300 Process Analyser

The OMA is an industrial device which measures a high-resolution absorbance spectrum in a continuously drawn sample from a liquid or gas process stream. Harvesting this rich data, the OMA process analyzer provides real-time analytics for the process stream, including chemical concentrations, purity, and color.

Chemical Concentrations:

The OMA can simultaneously monitor up to 5 chemicals in the sample stream. All analytes must have distinct absorbance curves in the 200-1100nm UV-Vis/SW-NIR wavelength range to be measurable by the OMA.

Chemical Purity:

By measuring a high-resolution transmittance spectrum, the OMA can very precisely detect impurities in the sample fluid by sudden changes in the spectral structure.

Physical Properties:

Various properties such as the heating value of a fuel or the octane of a gasoline blend can be powerfully correlated to the absorbance spectrum of the sample.

Specialized OMA Solutions:

Ammonia Analyzer

BTX Analyzer

Chlorine Analyzer

Clean-in-Place Analyzer

Color Analyzer

Continuous Emissions Analyzer

  • carbon dioxide | CO2
  • ethylene | C2H4
  • methane equivalency | CH4
  • water | H2O


Mix-2000 Digital Gas Mixer

The automated gas mixing system from Applied Analytics utilizes cutting-edge mass flow controllers to achieve the precision and repeatability required for demanding applications like research and instrument calibration.


Headspace Sample Conditioners

When a liquid is too opaque or dirty to transmit a light signal, direct optical analysis may be impossible. In this case, the composition of the liquid can be measured by heating the sample and analyzing the vaporous 'headspace' gas. The headspace sampling system design uses Henry's Law to provide a highly effective analytical solution for opaque liquids, including: crude oil, dirty wastewater and amine solution.



SERVOFLEX Micro i.s (5100 i.s)

The SERVOFLEX Micro i.s is a single component Intrinsically Safe Portable Gas Analyser that is certified to zone 0 and zone 1.

Technology Used

Oxygen – a choice of two Servomex paramagnetic transducers (standard or high accuracy) both offering fast selective measurement of oxygen without the disadvantages of electrochemical or zirconia cells.
Carbon Dioxide and Carbon Monoxide – Single beam, single wavelength infrared technology using Servomex patented long life source gives a highly stable, selective and low maintenance measurement.
