Raman Laser Gas Analyzers (RLGA)

OEM and critical spares

ARI’s cutting edge analyzer core is the foundation that the RLGA product line is built upon. Based on Raman Spectroscopy, this laser-based analyzer core can be integrated into other products or used as a field replaceable spare for critical uptime applications.

Key Features

  • Fast Analysis: Down to 1 sec.

  • High Sensitivity: Low ppm

  • Wide Dynamic Range: ppm to 100%

  • Multi-Species: 8 Simultaneously

  • Low Maintenance: Annual PM Schedule

  • Simple: Easy to Setup & Use

IntraCavity Raman Technology

ARI’s Gas Analyzers use a novel IntraCavityTM approach, where gas samples are sent into a gas cell and exposed to laser radiation. The resulting Raman signal is then collected through 8 distinct optical filter channels, each mapped to a factory-configured gas species of interest. This approach enables superior sensitivity without complicated chemometrics software. All 8 optical channels and their corresponding gas species can be measured simultaneously with configurable averaging times, based on process requirements. Additionally, by eliminating all fiber optics, the laser is completely isolated from human exposure and well under the explosion safety threshold of 35 mW, providing superior safety.

Demonstrated Species

H₂, N₂, O₂, Cl₂, CO, CO₂, H₂O, H₂S, SO₂, SO₃, COS, NH₃, NO₂, N₂O, HCl, CH₄, C₂H₆, C₃H₈, C₄H₁₀, DME, C₂H₂O, C₃H₆O, or a general CₓHᵧ aggregate.
