PURPOSE:To stabilize chemical reaction quickly by binding a pair of metal blocks, which are arranged so as to hold the main body of the flow cell and thermoelectronic elements, by binding members which are separated from the flow cell main body and the thermoelectronic elements. CONSTITUTION:The thermoelectronic element constitutes a heating surface HP and a cooling surface CP. The metal blocks 14 and 15 are heating fins which supply heat of external air to, e.g., the cooling surface CP of said thermoelectronic element 13. A pair of throughholes 14a are provided in the heat absorbing fin 14, and a pair of female screws 15a are provided in the heat absorbing fins 15. Steel bolts 16 are inserted in the throughholes 14a, and the tips of said steel bolts 16 are tightened by the female screws 15a. Thus a unitary body is assembled so as to hold the thermoelectronic elements 13 between the flow cell main body 10 and the heat absorbing fins 14 and 15. In this constitution, the object to be measured is efficienly heated, and the chemical reaction is quickly stabilized. |
