VA-5000-Siloxane
Total Siloxane Analyzer
The VA-5000 Total Siloxane Analyzer delivers high-sensitivity, continuous monitoring of siloxane in gas streams, with optional simultaneous measurement of methane (CH₄) and carbon dioxide (CO₂). Customizable to the type of cyclic siloxane being tested, this analyzer is ideal for durability testing, biogas fuel quality control, and preventing siloxane-related wear in gas engines.
Why Choose VA-5000-Siloxane
Sensitive, Real-Time Siloxane Detection – Measures siloxane concentrations continuously with high accuracy.
-
Optional Multi-Gas Capability – Can concurrently monitor CO₂ and CH₄ for comprehensive fuel assessment.
-
Supports Durability Testing – Useful in relays, motors, and contact parts to prevent siloxane-induced failures.
-
Protects Biogas Engines – Prevents damage by tracking siloxane levels in biogas before combustion.
