Moss Landing Air: Is there a difference between air monitoring and air sampling?

Return to: Frequently Asked Questions

Yes. Monitoring and sampling are used to accomplish different goals. Air monitoring is often used for emergencies because you get results immediately. Air sampling collects a sample over a longer period of time. The air sampling results show the average concentration over many hours, but air monitoring shows patterns and changes in real time.
