tracergastesten
Tracergastesten is a testing approach that uses tracer gases to characterize transport processes, such as flows, mixing, or leakage, within a system. The basic idea is to introduce a known amount of a safe tracer gas and monitor its concentration at strategic locations to infer rates or pathways of transport.
Common tracer gases include inert gases such as helium or sulfur hexafluoride (SF6) in small quantities, or
Applications include evaluating ventilation effectiveness in buildings (air exchange rates and airflow patterns), locating leaks in
Advantages include the ability to study transport dynamics noninvasively and with high sensitivity; limitations include the
Regulatory and safety considerations emphasize containment, appropriate tracer selection, and proper disposal. Tracergastesten is typically conducted
