Improve Sampling and Detection of Carbonyls in Air
Leverage a Wide Range of Samplers and Accessories
Achieve sensitive and reliable results with air sampling media for a wide range of applications in various configurations for solvent desorption, thermal desorption, passive and whole air sampling from Supelco. Ensure low background for carbonyl sampling with products that are produced to the highest quality standards in a carbonyl controlled manufacturing environment that is complemented by high-purity solvents and calibration standards.
The sampling of aldehydes and ketones requires an on-site derivatization on a coated adsorbent e.g. with 2,4-dinitrophenylhydrazine (2,4-DNPH). Supelco's product range includes the low back pressure DNPH (LpDNPH) cartridges (available in 6 different configurations and 16 products) for active sampling,
which ensure longer pump operation, glass tubes (ORBO™) and DNPH coated filters as well as devices with otherwise coated adsorbents for sampling carbonyls. Our product range is suitable for OSHA, NIOSH, ASTM, EPA and CARB methods. For a complete overview on air monitoring from Sigma-Aldrich, visit SigmaAldrich.com/air-monitoring.
