The colorimeter is an instrument used to measure the color of a substance, using the RGB color system. This system uses three primary colors: red, green, and blue. Similarly, it measures the intensity of each and then combines them to create a color. It has an accuracy of 0.01%. This is very useful for chemists, as they can use the colorimeter to measure small amounts of substances. The colorimeter is also used in medicine, where doctors use equipment to measure the color of blood and other body fluids to detect diseases and medical conditions. It is a very useful instrument that is used in many fields. It is precise, easy to use and available in many sizes and shapes.
That said, the Kalstein colorimeter states that the absorbance of a solution is proportional to the concentration of the solution, which consists of a light source, a filter, a detector and a reading device.
Colorimeter Performance
The light source is usually a tungsten halogen lamp or xenon lamp. The light from the source passes through the filter, allowing only a specific wavelength of the light to pass through. The detector is usually a photodiode or photomultiplier tube. The detector converts the light into electrical signals. These electrical signals are amplified and displayed on the reading device.
The filter is the most important component of the colorimeter. The filter is selected so that only a specific wavelength of light can pass through. The wavelength of light that is allowed to pass through the filter is known as the cut-off wavelength. The cut-off wavelength is selected so that it is in the absorption spectrum of the solution.
The detector converts the light into electrical signals. These electrical signals are amplified and displayed on the reading device. The reading device can be a digital or analog display. The digital display is easier to use, as it shows absorbance directly in percentage.
Use of the Water Colorimeter
The colorimeter is a highly sensitive instrument and can detect ion concentrations in solution of only a few parts per million. The colorimeter is widely used in water analysis, as it allows to determine the concentration of certain ions in solution.
Water analyzes are performed to control the quality of water intended for human consumption, as well as for chemical industries and processes. The analysis is also used to monitor water from rivers, lakes and reservoirs, as well as seawater. The colorimeter is a very sensitive instrument and can detect ion concentrations in solution of only a few parts per million.
