Steps To Using The Colorimeter Effectively

In the past, color played an important role in defining the purity of any item

, whether it was fruits, vegetables, grains or water. Soon, this manual attempt at deciding quality was taken up on a scienticifc level and converted into a full fledged principle knows as Colorimetry.

Colorimetry is a unique technique that is used for checking the concentration of colored compounds in a solution. A handy device used for this purpose is known as a pocket colorimeter. It determines the absorbance of light by various colors in different environments. This write-up will explain exactly how this device works.

The pocket colorimeter II and its previous counterpart are used widely for testing and work on the Beer-Lambart law, which states that concentration of a particular color in the solution is based on the absorption of light by the shade. While there are several different types in this device, their working is more or less similar.

When measuring, know the requirements of a particular device and ensure that same is used every time for accurate results. The main thing to observe in any colorimeter is to look for the difference in shade and hues. Hence, you may often find a change from clear to a colored solution, one color to another depending on the turbidity as well as colored to clear.

While this transition of colors speak a lot about the water quality, it is possible that some shades maybe more crucial than the others. This is because it may reflect serious pollutants or contaminants in the water. This is why you may need to use multi parameter colorimeters. Lets understand how these devices work.

You may start using this device by first allowing it to stabilize for five to ten minutes after you switch it on. Next, comes the crucial part of picking an appropriate filter. These are mainly utilized for isolating parts of visible light spectrum, which are most absorbed by liquid. While it depends from one device to another, here are a few predictable wavelengths of different colors:

Red filter: 630-750nm

Green filter: 510-570nm

Blue filter: 360-480nm

Once you have fixed on a filter you may insert in the light path. After this procedure, you may get the sample solution or water and place it in the cuvette. Ensure that while doing this, the clear faces of the cuvette are in the light path. Now, you need to read the absorbance of the solution. If it is above the range, which is usually less than 2.0, then you must dilute the solution that matches the limits of device. Dont forget to check sample so that there is no drift in the zero value.
