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
Measurement of PFAS in indoor air and investigation of source materials
Application Note 167
Simplifying GC–MS sample preparation for product and material testing
Webinar addressing analysts’ needs for a robust and reproducible approach to sample emissions from a wide variety of materials and products, for analysis by GC–MS, and to answer such questions as: What’s that smell? Is my product safe? Is there anything toxic in my home/car? How can I detect a harmful chemical from a material?
Key considerations when switching from solvent extraction to thermal desorption
Download this useful infographic, which compares solvent extraction and thermal desorption in terms of their cost and benefits to data quality.
Passive sampling in the workplace: Why thermal desorption is replacing solvent extraction
Discussing why solvent extraction of sorbents remains so widely used for passive monitoring of workplace atmospheres, and showing that TD is not only better from a health & safety perspective, it’s better for lab budgets too.
Why are Markes’ thermal desorption sorbent tubes better than those from other suppliers?
