FIELD: methods of impurities concentration in gasses to increase capability of their detection. SUBSTANCE: apparatus for realization of method is made in the form of tube with layer of sorbent particles and provided with heater. Layer is made of inert nozzle, on surface of which sorbent particles are located. Members of nozzle are pieces of wire spirals. Sorbent heating is exercised by heater motion along tube. Main distinguishing feature of apparatus is the fact, that it uses fine dispersed sorbent with low resistance to air flow in narrow tube. It improves kinetics of sorption and that is more important kinetics of desorption. Apparatus is used as permanent part of detector. As a version it is used separately from detector to take samples. EFFECT: apparatus allows to improve main operational characteristics of concentrators with solid sorbents. |
