Advantages And Disadvantages of Friction

Some of the Advantages of Friction are:

  1. We can walk with the help of friction between our shoes and the ground.
  2. We can write with pencil or pen on the paper on the board using friction.
  3. Cars or other vehicles uses friction (Breaks)  to stop the vehicle.
  4. Friction helps in running and walking on the ground or the floor.

Some of the Disadvantages of Friction are:

  1. Sometimes friction produces heat in the machinery or its parts.
  2. Friction makes wear and tear of the machinery

Advantages and disadvantages of solid phase extraction

Solid phase extraction:Let us discuss advantages and disadvantages of solid phase extraction. Some of them are discussed below so let us check it out one by one.

Advantages:

No emulsion problems observed.

Cost is low

Accuracy is greater

Glass breakage minimal

Lower solvent consumption

Reagent consumption lower

No cross contamination

Less sample handling

Process in fewer steps

Disadvantages:

Incomplete removal of the interferences

Advantages of an Wind Power

ADVANTAGES OF WIND POWER:

The wind is free source and it can be captured very easily with modern technology.

Once turbine is built lot of energy can be produced and it is pollution freen and do not cause green house effect.

In remote areas aslo this type of energy can be produced.

In small villages energy can be generated using this wind turbine. 

It is renewable source of energy

Less air and water pollution

It also reduces consumption of fossil fuels.

Advantages and disadvantages of Chromatography

Chromatography is simple method. Chromatography can be handled by single person.

Other advantages are, Chromatography is used to separate components from complex mixture.

Different types of chromatography equipment are available for separation of different compounds.

Some of them are Gas Chromatography, Liquid Chromatography, Solid Chromatography, High performance liquid Chromatography, Solid liquid Chromatography, Liquid liquid Chromatography, Thin layer Chromatography. This method gives accurate results.

Disadvantages & Advantages of an TLC

Some Disadvantages & Advantages of an TLC.

In Thin layer Chromatography also called (TLC) is widely used method for the separation and detection of an molecule from a given mixture of compounds.

This method is used for the separation of non volatile compounds.

This is generally performed on the thin sheet of aluminum or thin sheet of glass or plastic.

This sheet are coated with different media, commonly used are silica gel, cellulose etc.

The sample is applied on this plate and it is called stationary phase.

Disadvantages & Advantages of an GC

Disadvantages & Advantages of an GC.

Gas chromatography (GC) is an analytical method which is used for the separation of an volatile substance from a give mixture of compounds which are very difficult to separate and analyse.

This type of chromatography separates the molecules based on the volatility of a substance.

The substance with more volatility will separate out quickly while the substance with less volatility will elute out slowly.
