Hello, readers welcome to the new tutorial. we will discuss Difference Between a Colorimeter and Spectrophotometer. these two are instruments that used for measuring the light-absorbing capacity of different materials. A spectrophotometer is used to measure the light transmitted and reflected when passes through any solution. While colorimeter is used to measure the quantity of solute in solution by measuring the light absorbed by the solution when passed to it.
In this post, we will discuss these meters working and other basic parameters to find differences. So let’s get started.
Difference Between Colorimeter and Spectrophotometer
What is Colorimeter
- It is a device that is used to find the value of light rays absorbed by the solution.
- It is used to find the quantity of solute existing in the solution through use of Beer-Lambert Law which says solute concentration is directly proportional to light absorbance.
Colorimeter Working
- The working principle of the colorimeter is based on the Beer-Ambert Law which states that light absorption and solute in the solution are directly proportional to each other.
- For measuring the color over the given standard colorimeter transit light through the liquid
- The lens of a calorimeter and tristimulus absorption filter converts the light rays into a single wavelength
- Photocell shows light absorbed and modules shows outputs at the screen
- This meter is used for making a comparison between the new and old results.
- Its common uses are for measuring yeast growth, asses beverage color, and the quantity of ink used in printers.
- Its sensitivity is less and low cost
- It is a static meter
- It is used for Psychophysical analysis and is less sensitive
- Its cost is less and its structure is less complicated
What is Spectrophotometer
- The branch of electromagnetic spectroscopy that deals with quantitative measurements of reflecting features of material of light waves is called spectrophotometry.
- Spectrometry uses photometers that are called spectrophotometers can measure the intensity of light rays having different wavelengths
- Spectrometry is used for UV, visible, and IR radiations but modern techniques are also applicable for electromagnetic spectrum like X-ray microwaves
- It is a device that is used to measure the light absorbed by the colored compounds.
- It is mainly used for measuring the transmittance and reflection of the solution of opaque and transparent objects.
- It is used for physical analyses of substances.
- Its sensitivity is larger than the colorimeter.
- Expensive than the calorimeter
- The structure is more complicated than the calorimeter.
- This meter is used in different fields, such as microbiology, biochemistry, physics, etc.
- Different particles used in drugs and medicines can be found whether they are helpful for use or not.
- Used for measuring bacterial growth and used for measuring the uric acid in urine
- For the progress of the reaction, scientists used this meter.
What is the difference between calorimetry and spectrophotometry?
- Clorometery and spectrophotometry are different in the sense that colorimetry uses fixed wavelengths that are observable in the visible spectrum, and spectrophotometry can use a larger range of wavelengths.
What is the principle of a spectrophotometer and colorimeter?
- Spectrophotometers are used for measuring the color-absorbing features of materials. The basic difference between them is that spectrophotometers find the value of transmittance and reluctance for function wavelength, and colorimeters measure the absorbance of specific colors.
What is colorimetry and spectroscopy?
- Colorimetry measures the wavelength and intensity of electromagnetic radiation for the visible region of the spectrum. It is used mostly for the identification and determination of the concentration of materials that absorb light.
What is a colorimeter used for?
- The colorimeter is used for measuring the concentration of chemicals in solution if a chemical has features of color of solution. The colorimeter optical system separated narrow wavebands of light for the selected absorption peak of the chemical measured.
What is the basic principle of colorimetry?
- When a beam of monochromatic light passes through the colored solution, coloring materials absorb part of the light and the remaining is transmitted. Light absorption is based on color intensity.
What are the disadvantages of a spectrophotometer?
- The limitation of spectrophotometry comes with relatively low sensitivity and selectivity. It can be difficult to check low concentrations of analytes or differentiate analytes from other materials that absorb light with the same wavelength.
That is all about the. Difference Between Colorimeter and Spectrophotometer all details has been explained. If you have any further queries ask in the comments. Thanks for reading have a good day see you in next post
