Laser - Model 5100 HD

Using tunable diode laser absorption spectroscopy (TDLAS) technology, the 5100HD can be configured with one or two absorption cells, providing dual stream analysis and/or the measurement of multiple analytes at the same time.

The tunable diode laser technique is inherently free from many problems that affect physical contact sensors, including repeated exposure to contaminants and a delayed measurement response to sudden process upsets.

Two separate lasers can be installed in the instrument, sharing a common optical path through the sample. This results in significant cost savings by eliminating the need for a second analyzer in the process.

Measuring combinations of water vapor, methane, hydrogen sulfide, carbon dioxide, acetylene and oxygen, the 5100HD is designed for applications in the hydrocarbon processing and natural gas industries.

Proven, laser-based measurement ensures that the sample never comes into contact with key optical components. This means that both the light source and the detector are unaffected by the gas stream, preventing contamination or damage.

The 5100HD uses sealed reference cells, which contain known amounts of the analyte gases measured, for referencing the emission wavelengths of the lasers. This enables the ability to line-lock the lasers and to continuously verify the optical system performance.

Housed in an IP 65/Type 4X enclosure for installation in outdoor or hazardous areas, the 5100HD can be configured with a fully integrated sample handling system and is capable of operation in a wide range of challenging environments.

The 5100HD is our extractive-type TDLAS analyzer for dual analytes, or those streams with high sample dew points. – Find out more.
