TO-15A: Is your pre-concentrator system up to the task?
On-demand webinar. Discover how to reach method detection limits for 20 ppt for all environmental 'air toxics' compounds as laid out in USA EPA Method TO-15A.
Monitoring of ozone-depleting substances (ODS) with pre-concentration and GC–MS
Watch this webinar to learn (i) how monitoring of ozone depleting substances is carried out at the global scale through networks such as AGAGE, (ii) about the MEDUSA system and the data it generates, and (iii) how Markes’ TD systems are being used for monitoring of ODS.
Balancing lab sustainability and expanding VOC monitoring requirements for air analysis
Air monitoring lists are growing in complexity, such as in ozone precursor monitoring, air toxics, and organic ozone-depleting substances. This webinar investigates how the methodology can meet the requirements of monitoring, while considering how the method can be made more sustainable, reducing running costs
