SPECTRAL DEVICE HOLDING CONSTANT TEMPERATURE CIRCULATION CELL AND PELTIER ELEMENT CELL IN COMMON

摘要

PURPOSE:To recheck easily measurement data by disposing and installing a constant temp. circulation cell vessel and Peltier element cell vessel in a spectroscope sample chamber on the optical axis and changing over a square cell and flow cell with a finger-tip operation. CONSTITUTION:The constant temp. circulating water system cell holder vessel and Peltier element flow cell vessel are commonly provided in the spectroscope sample chamber. Measuring samples are introduced through a sample intake tube 6 into the flow cell 1 in the stage of measuring the multiple samples. The samples are maintained at the specified temp. by the Peltier element 3 and is prevented of the intrusion of external heat by a heat insulating block 2 so as to make stable coloration. After the absorbancy, etc. thereof are measured, the samples are discharged from a discharge tube 7. The square cell 9 is inserted into the constant temp. circulating water block 8 and a cell fitting 4 is glided to deviate the Peltier element vessel from the optical axis. The variance in the measured values and abnormal values in the measurement of the multiple samples are measured and checked again by the square cell 9.
