Abstract

In this work, SBA-16 and HKUST-1 have been investigated as alternative adsorbents for benzene and toluene preconcentration and compared with Carbopack B, the reference material for VOC sampling. They have been fully characterized and assessed in terms of preconcentration performances. For both materials, preconcentration tests shown higher preconcentration factors than the ones obtained with Carbopack B. Using these sorbents in a preconcentrator device, the detection limit of our miniaturized GC prototype was calculated to be 0.2 ppb for both compounds. Both adsorbents are promising for environmental applications in BTEX monitoring.
