Abstract
PURPOSE: To enable to measure the degree of deterioration quickly and simply, by measuring the intensity or induction period of chemical light emission of fat and oil.
CONSTITUTION: The sample such as food oil and lubricant oil is contained in the vessel 11 and N2 gas is fed from the inlet 15 to the vessel via the flowmeter 16. The vessel 11 is heated with the heater 14 and temperature can arbitrarily set from room temperature to 250°C with the thermocouple 12 and the temperature controller 13. The intensity of chemical light emission or its induction period in wavelengths 400W600nm is displayed and recorded on the digital display unit 18 and the recorder 19 by using the unit consisting of photo electron multiplier 1, preamplifier 2, pulse amplifier 3 and peak discriminator 4, pulse counter 5 and gate signal generator 6. The high voltage source 20 is used for the power supply. The heat isolation cooling section 7 and the shutter 8 are provided at the photo detection side of the multiplier, the filter wheel 10 of the 18 holes mounting the cut-off filter 9 is provided in front of it, and the entire sample vessel is sealed optically with the light shield box 17. The analytical value can be obtained by using this unit and comparing it with the measurement curve of the standard sample measured in advance.
