The aim of this study is to assess the efficiency of the Coriolis® μ air sampler for the active capture of volatile compounds. Formaldehyde has been chosen as a suitable model volatile due to its high volatility, low molecular weight (30 MW) and ease of detection.
● Coriolis® μ is able to detect <5 μl of a 37 % solution of formaldehyde in a very short sampling time (10 min), equivalent to 264 μg.m-3 formaldehyde at 20°C.
●Further assays on experimental parameters (i.e. sample volume) may further increase the sensitivity and extraction efficiency of the air sampler.
