A new measurement solution that contributes to improve productivity in petrochemical plant manufacturing processes*¹.
The PLGA-1000 Process Laser Gas Analyzer is designed to measure hydrocarbons and other gases contained in process gases at petrochemical plants. The PLGA-1000 uses proprietary technology to measure low concentrations of acetylene (C2H2) and carbon dioxide (CO2) contained as impurities in high concentration methane (CH4) and ethane (C2H6) which are material gases, continuously at high speed and with high sensitivity . This contributes to improvements in productivity, cost, and quality in the manufacturing process, as well as reducing environmental impact.

Delivering New Benefits with Innovative Technology
HORIBA’s proprietary IRLAM™ *¹ (InfraRed Laser Absorption Modulation) technology realizes new solutions for specific manufacturing process that have been difficult to achieve with process gas chromatograph measurements.
Significant Improvement of Process Control With More Accurate and High-Speed Stable Continuous Gas Measurement
Significant Improvement of Process Control With More Accurate and High-Speed Stable Continuous Gas MeasurementContinuous measurement of low-concentration impurity gas in high concentration hydrocarbons accurately in a short measurement time.
– High sensitivity measurement: ppb level (Low concentration impurities in high concentration hydrocarbons are measured at ppb level.)
- Fast response time: 3 seconds (for details, see response time in specifications)
Operational Cost Reduction
A column-free gas analyzer that uses IRLAM technology. Furthermore, the frequency of replacement parts and calibration is reduced by using a laser as the light source.
Compact Installation Area
The use of a small gas cell (Herriot cell), etc. reduces the footprint of the analyzer and contributes to save your space.
