DISPOSITIVO E PROCESSO DE MEDIÇÃO DE MODO CONTÍNUO DA CONCENTRAÇÃO TOTAL EM ALCATRÕES DE UM GÁS

摘要

The device has two measurement lines (B1, B2) respectively equipped with detectors (32, 26) e.g. photo-ionization detector. An extraction unit is formed by a thermostatically controlled sampling shell (12) and solid phase micro extraction fiber (13) and extracts samples from gas. A capillary column (25) is placed upstream of the detector (26) and separates tar components from the gas. The fiber is made of polydimethylsiloxane. A processor (36) is connected to the detectors and synchronizes the detectors.
