Colorimeter | Principle | Part | Advantages and disadvantages | Applications

 What is a colorimeter?

A colorimeter is a piece of equipment used in colorimetry. It refers to a system that aids in the absorption of a certain wavelength of light by a specific solution. Using the beer lambert law, the colorimeter is used to determine the concentration of a specified solute in a given solution.

Principle of colorimeter:

It is a photometric technique which states that when a beam of an incident of the intensity I০ passes through a solution, the following occur:

  • A part of it is reflected which is denoted as Ir
  • A part of it is absorbed which is denoted as Ia
  • The rest of the light is transmitted and is denoted as It
Therefore Io = Ir + Ia + It

Where 

Ia  = the measurement of  Io and It is sufficient therefore Ir is eliminated. To calculate Io and It, the amount of light reflected is kept constant.

A colorimeter is based on two basic photometric rules

Beer's law:

The amount of light absorbed is proportional to the solute concentration in the solution, according to this law.

LOg10 Io/It = As * C

Where, 

As is absorbency index

C is the concentration of the solution

Lambert law:

The amount of light absorbed is proportional to the length and thickness of the solution used for analysis, according to this law.

A = log10 Io/It = As * B

Where 

A is the test absorbance of the test

As is the standard absorbance

B is the length/thickness of the solution

Part of colorimeter:

There is 5 essential part of colorimeter:

  1. Light source
  2. Monochromator
  3. Sample holder
  4. Photodetector system
  5. Measuring device
Light source: The most common source of light used in the colorimeter is a tungsten filament.

Monochromator: To pick a specific wavelength, monochromators or filters are used to split the light from the source.

Sample holder: Color solutions are kept in test tubes, which are made of glass with a visible wavelength.

Photodetector system: As light strikes the photodetector device, an electric current is produced, which is used to produce the reflected galvanometer reading.

Measuring device: The current from the detector is fed to the galvanometer, which displays a meter reading that is directly proportional to the light intensity.

Working of colorimeter:


Working of colorimeter

  • It is important to calibrate the colorimeter before beginning the experiment. It's done with the help of standard solutions containing the calculated solute concentration. Place the cuvettes in the colorimeter's cuvette holder and fill them with normal solutions.
  • In the direction of the solution is a light ray of a certain wavelength that is specific for the assay. The light is filtered through a series of lenses and filters. The colored light is guided by lenses, and the filter splits a beam of light into different wavelengths, allowing only the appropriate wavelength to pass through and enter the regular test cuvette.
  • When the light beam crosses the cuvette The solutions transmit, reflect, and absorb the light. The photodetector device tests the strength of transmitted light when the transmitter ray hits it. It transforms it into an electrical signal, which it then sends to the galvanometer.
  • The electrical signal measured by the galvanometer is displayed in digital form.
  • Formula to determine substance concentration in test solutions
                A = 𝞊cl
for standard and test solutions:

𝞊 and i are constant

AT = CT...................(1)
AS = CS...................(2)

AT * CS  = AS * CT

CT  = (AT / AS) * CS

Where,

CT = Test solution concentration

AT  = Absorbance density of test solution

CS = the standard concentration

AS = Absorbance/optical density of standard solution

Advantages and disadvantages of colorimeter:

Advantages:

  • Result available in less than 1 second
  • A handheld and pocket-sized colorimeter can make between 100 and 300 measurements of four AA batteries.
Disadvantages:
  • The colorimeter is fairly expensive.

Pros and cons of CISC

The complex instruction set computer (CISC) was created to make compiler creation easier and more straightforward. There is a form of chi that is simple to program and makes good use of memory. So, in order to better understand this subject, this article discusses the benefits and drawbacks of CISC architecture.

Pros of CISC | Advantages of CISC:

  • In CISC it is easy to add the new command into the chip without the need to change the structure of the instruction set.
  • Instructions are at a high level when compared to RISC, programmers or compilers for CISC have lesser workloads.
  • The hardware does more of the work in decoding instruction. The complexity of instruction means less memory requirement.
  • Mircoproamming is a simple and inexpensive alternative to hardwiring a control unit.
  • As a result of the architecture, you can make efficient use of main memory.
  • As in the case of CISC, the compiler should not be overly complex. The instruction sets may be written to correspond to the structure of high-level languages.

Cons of CISC | Disadvantages of CISC:

  • They are larger as they require more transistors.
  • This architecture necessitates chip hardware to be continuously reprogrammed.
  • Because of its sophistication, it is more costly to implement than RISC.
  • CISC centers on minimizing the memory requirement. Memory back then was small and expensive. This is not the case today.
  • Since the clock time taken by various instructions will never be the same, the machine's output will slow down.
  • Many functions are performed by the complexities of hardware and on-chip software used in CISC design.

Colorimeter vs Spectrophotometer

What is a colorimeter?

A colorimeter is designed to perform a type of psychophysical sample analysis, which means its measurement correlates to human perception. To put it another way, it's made to see color the way we do.

What is a spectrometer?


The spectrometer is an instrument designed for a physical sample analysis via a full spectrum color measurement. by providing wavelength by wavelength spectral analysis of a sample's reflectance, absorbance, or transmittance properties.

Difference between colorimeter and spectrometer:

  • A colorimeter is a general type, while a spectrometer is a specific type.
  • A colorimeter is limited to the visible light only with WL 400-700nm, while the spectrometer can be extended to x-ray, UV light, infrared, and radiofrequency.
  • Colorimeters 2 digit reading after the decimal point,  while the spectrometer is 4 digit reading after the decimal point.
  • The calorimeter consists of a sensor and simple data processor, while the spectrometer consists of the plus data processor or computer with software.
  • Both of them measure the color and intensity of color through light.
  • The basic method of operation is similar for all instruments.
  • the colorimeter is cheap, while the spectrometer is very costly.
  • Colorimeter utilizes three-color generally, red, green, and blue generated either color wheel with a color filter or set of specially designed LEDs. While spectrometer utilizes either a diffraction grating or prism in the sensor.
  • The calorimeter consists of a rugged and less complex instrument than a spectrometer, while the spectrometer is a more complex instrument than the colorimeter.
