FAQs About  Spectrocolorimeter

The principle of colorimetry is the law of Beer-Lambert, which says that the intensity of light absorbed by a colored solution is proportional to the concentration of the absorbing species and the path length. It measures the extent of light that is absorbed at certain wavelengths.


A colorimeter sends light through a solution and measures the amount that is absorbed. It computes the absorbance by comparing the intensity of light before and after passing through. The greater the concentration of the color, the greater is the absorption of the light. It is also possible to quantify the color of the solution.


The various colors can be measured by the way a surface reflects, absorbs, or transmits light at different wavelengths. These responses may be measured using instruments such as colorimeters or spectrophotometers to give numeric values in a standardized color space such as L *a*b*.


Record the L*a*b values of the sample and the reference with a calibrated spectrophotometer or colorimeter. Compute the difference in the color by use of ΔE. The lower the Delta E, the more accurate the result. The difference in energy, ΔE < 1, is generally assumed to be invisible to the eye.


The concentration of colored compounds in a solution is determined by the use of a colorimeter test. It can be used to measure the quality of the product. The colorimeter test determines the presence of contamination or observes chemical reactions by measuring the extent to which a solution absorbs light at a given wavelength.
