FAQs About  Spectrocolorimeter

A calorimeter is used to measure heat that is gained or lost during a chemical or physical reaction. A sample is taken in an insulated container, and a temperature change is measured. This assists in computing the alterations in energy by the equation Q = mcΔT, where Q is heat.


To quantify color change, take the original L*a*b* values of a sample, and reread after exposure or processing. Compute the difference as 1/2(Emut1 Emut2). The larger the value of ΔE, the more obvious the change of color is, which can be used in quality or stability testing.


The most important equation is A = 2εcl, where A is the absorbance, 2 is a constant, ε is the molar absorptivity (L/mol cm), c is the concentration (molL-11), and l is the path length (cm). This can be used to relate the absorbance to the concentration, allowing quantification through colorimetric assays.


L*a*b* is an L*a*b* color space. The L* is a measure of lightness (as 0 = black, 100 = white), a* indicates the green to red axis, and b* indicates the blue to yellow axis. It is also common in color measurement in terms of precision and reliability.


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*.
