Description
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.
