Abstract
PURPOSE:To rapidly remove high concn. carbon dioxide remaining in a measuring means, by increasing the flow rate of inert gas when a detected value transfers from a high concn. value to a low concn. value. CONSTITUTION:The liquid specimen and reaction liquid supplied to a reactor at a constant flow rate by a pressure pump 10 react each other to form carbon dioxide. Cooling water recirculated to the pipe around an extractor 20 and carbon dioxide becomes a bubble state in the inert gas supplied from a pipe 21 to be separated from the liquid specimen supplied from the reactor 12 and sent to an infrared analyser 23 through a pipe 22. A control apparatus 31 for controlling the flow rate of the inert gas from an inert gas supply source 8 is provided to the mass flow controller 30 provided on the way of the pipe 21 and the concn. data of carbon dioxide detected by the infrared analyser 23 is appropriately inputted to the control apparatus 31. The control apparatus 31 outputs a signal for a definite time when the value of the concn. data largely lowers to increase the flow rate of the inert gas and the high concn. carbon dioxide gas is substituted with the inert gas low in the content of carbon dioxide in the infrared analyser 23.
