Inner temp. calibration gas generator vessel located inside outer vessel

摘要

A calibrating gas generator (1) incorporates two vessels (2,3) through which a carrier gas flows in series and which holds a calibrated solution (4,5) below calibrating gas (6,7) chambers. The carrier gas passes via a tube (8) through the calibrating gas solution (4) in the first vessel (2) through the first gas chamber (6) via a tube (9) through the calibration solution (5) in the second vessel (3) to an outlet (10). The temperature of the calibrating solution is held constant by a heater (11) and thermostate (12). The novelty is that the second (3) vessel is located partly or totally inside the first (2), and that the outer vessel serves as a heat-insulating mantle for the inner vessel.
