Sampling of Carbonyls Using a Dual-Layer LpDNPH Glass Sampling Tube and HPLC Analysis with an Ascentis Express C18 Column

The dual-layer LpDNPH ORBO-555 tube is an effective sampler for measuring airborne carbonyl concentration. The low background levels in the sampler allow for accurate measurements of low concentration samples or samples collected in situations where short sampling times are needed. The results indicate that under the sampling conditions employed, there was no breakthrough of formaldehyde, acetaldehyde, acetone, or hexanal.
