There is a very high correlation between the measurement values according to JIS standards and the wastewater from various business sites.
This measurement method uses the same reaction conditions for pollutants and potassium permanganate as JIS K 0102, and the volumes of the sample and reagents are conducted at one-twentieth of the JIS method. Heating at 100°C for 30 minutes is performed using a reactor instead of a water bath, and the amount of consumed permanganate ions is determined by measuring the decrease in absorbance with a photoLab 6100 water quality meter instead of using titration, displaying the COD concentration. Since the reaction conditions of this method are exactly the same as those of the JIS method, there is a very high correlation between the measurement values obtained by the JIS method and those obtained using the photoLab 6100.

basic information
■Features ○ High correlation with JIS method The reaction conditions for all processes are identical to the JIS method, showing a very high correlation (r2=0.99) with measurement values from the JIS method for various industrial wastewater. ○ Significant reduction in waste liquid volume The volume of waste liquid is very small, only one-twentieth of that of the JIS method, greatly reducing environmental burden. ○ Very simple measurement operation After heating and decomposition treatment, the sample can be measured for COD concentration easily and quickly with the photoLab 6100 model without titration. ○ Simultaneous pretreatment of multiple samples, reducing measurement time Pretreatment of 24 samples can be done almost simultaneously, significantly shortening measurement time. ■Reactor (choose from 2 types) Seven standard decomposition programs tailored to measurement items are stored in memory and can be easily selected. Additionally, the CR3200 reactor can store up to eight user-defined decomposition programs. All reactors are designed with sufficient safety measures and excellent thermal conductivity. They include a safety hood to prevent splashing, a timer function, and a decomposition temperature display function.
