Request information Nov 03 Read Times Capillary electrophoresis CE is a widely used technique in biosciences. Some of the main uses of CE include: Separation can be at a resolution of one base pair and individual nucleotides can be identified so allowing a high resolution map of the DNA to be created.
It is a very similar technique to column chromatography. Gas Chromatography is now a days widely used technique for the separation of gaseous and volatile substance which are difficult to separate and analyse. Gas Chromatography have many applications for separation of volatile sample. Advantages of Gas Chromatography are as follows: This technique has a high resolution power compared to others.
Sensitivity in detection is very high with thermal conductivity detectors.
One can detect upto ppm, while flame detectors, electron capture and phosphorus detectors can detect ppm, parts per billion or picograms respectively.
It gives relatively good precision and accuracy. It is a micromethod hence very small size is required hence micro litre of sample is sufficient for complete analysis. The speed of analysis is very fast. The use of a gas as the moving phase has the advantage of rapid equilibrium between the moving and stationary phases and allows use of high carrier gas velocities, leading to fast analysis in seconds, minutes or in hours.
It involves relatively simple instrumentation operation of gas chromatography and related calculations don not require highly skilled personnel and thus the technique is suitable for routine analysis.
Qualitative as well as quantitative analysis at a time is possible. The area produced for each peak is proportional to that concentration.
The cost of gas chromatography is very low as compared to the data obtained. These are some of the advantages of Gas chromatography.Advantages and disadvantages of paper chromatography Paper chromatography is the oldest technique of separation of analytes from the sample; it is applied particularly in the analysis of lipid samples and chemical compounds.
Disadvantages of Paper Chromatography:Like all analytical methods, paper chromatography has its limitations. Some mixtures are very difficult to separate by paper chromatography; and any species that is not coloured is difficult to .
GC Advantages and Disadvantages. Gas chromatography has several important advantages which are listed opposite.
GC techniques produce fast analyses because of the highly efficient nature of the separations achieved – this will be studied further in the Band Broadening Section.
The Essence of Modern HPLC: Advantages, Limitations, Fundamentals, and Opportunities. Jun 01, By This article reexamines the fundamental concepts of high performance liquid chromatography (HPLC) to bring fresh insights to how we perform HPLC today.
It reviews the prominent advantages that render HPLC .
Advantages and Disadvantages of Capillary Electrophoresis Request information. Nov 03 Read Times. Capillary electrophoresis (CE) is a widely used technique in biosciences. The advantages of using capillary tubes are that lateral diffusion effects are reduced and temperature differences across the tube are reduced.
. ADVANTAGES OF PAPER CHROMATOGRAPHY 1. One of the major advantages of paper chromatography is the sensitivity with which compounds can be located after separation.
Amounts as little as microgram (one micrograms is one millionth of a gram) of some compounds can be detected with routine reagents. 2. The operation time.
