• Pt Co platinum cobalt chromaticity

Prepare platinum cobalt standard solution using potassium chloroplatinate and cobalt chloride in different proportions. The standard liquid color value that best matches the color of the tested sample is the platinum cobalt chromaticity value of the sample.

Application scope: Platinum cobalt chromaticity is suitable for colorless or light colored liquids, such as water used in the petrochemical, chemical, biochemical and electronic industries, new energy and new materials fields.

Color range: 0-500 Pt Co, the larger the value, the darker the color.

measurement method

Traditional colorimetric method: Place transparent electrolyte into a white colorimetric dish or tube that matches the quantitative standard, and directly observe the clarity and color depth with the eyes.

Visual colorimeter method: Using a visual colorimeter to compare with a colorimetric disc to obtain the platinum cobalt color of the electrolyte, this is a more simple and accurate measurement method.

Automatic colorimeter method: Using an automatic colorimeter and spectrophotometry to directly measure the platinum cobalt chromaticity of liquids, it is currently the fastest and most accurate measurement method.
