VA-5000 (Siloxane)

Total Siloxane Analyzer

VA-5000 Series Total Siloxane Analyzer continuously measures siloxane concentration in gases with high sensitivity. It is tunable according to the type of cyclic siloxane to be measured. It is also available to measure carbon dioxide and methane at the same time as siloxane. The system can be used for siloxane durability testing of contact parts such as relays and motors, impurity monitoring and fuel quality control in biogas power generation facilities, and many other needs.

Segment: Process And Environmental

Division: Process Gas

Stable continuous measurement with high sensitivity

Available for simultaneous measurement of CO₂, CH₄, and siloxane

Applications

Concentration monitoring of siloxane in siloxane durability tests and simulation tests of contact parts such as relays and motors

Total Siloxane Analyzer continuously and with high sensitivity measures the siloxane concentration during R&D and investigation, such as the siloxane durability tests and the simulation tests of contact failure due to siloxane adhesion.

Impurity monitoring and fuel quality control in biogas power generation facilities

Continuous monitoring of siloxane for prevention of gas engine damage due to siloxane adhesion to the inside of the gas engine. Methane (CH₄) and carbon dioxide (CO₂) measurement is also available for fuel quality control of gas engines.

Option

Preprocessing Cooler Unit for Total Siloxane Analyzer
PS-300S

When sample gas to be measured contains more than 5°C saturation moisture, please use Cooler Unit for dehumidifying and preparation of sample gas to be introduced to Total Siloxane analyzer.
