The manufacturing of elastomers makes wide use of 1,3-butadiene (CAS no. 106-99-0) and isoprene (2-methyl-1,3-butadiene, CAS no. 78-79-5). Both compounds are classified as carcinogenic by the International Agency for Research on Cancer (IARC). 1,3 butadiene is listed in group 1, carcinogenic for humans, and isoprene is in group 2B, possibly carcinogenic for humans. The measurement of these compounds in workplace air requires therefore high sensitivity and also the control of explosive hazards, which are frequent in chemical plants.

The diffusive sampling followed by thermal desorption and GC-MS analysis with the new radiello Butadiene sampler represents a simple and affordable tool for this measurement, while satisfying the above requirements.


The sampler consists of a cartridge adsorbent filled with Carbopack™ X, a graphitised carbon black developed and manufactured by Supelco, that is placed in the radiello yellow diffusive body (Product No. RAD1202). After sampling, the cartridge adsorbent is placed in a TD empty tube and analyzed by thermal desorption (TD)/GC-MS.

The nominal sampling rate (@20°C, 50% RH, for 8h exposure) for 1,3-Butadiene is 30,5 +/- 0,3 ml/min 34-2960 µg/m3 , for Isoprene 41,2 +/- 4,9 mL/min @ 2-6600µg/m3.
