Some drawbacks of gas chromatography include:
Difficult to reproduce, spots are often faint and not typically automated
spots are often faint, and TLC is difficult to reproduce. NOT typically automated
more points on liquid chromatography:
Gas chromatography can only be used in cases where the substances can be vaporized without decomposing and where they can be vaporized at a reasonable temperature (i.e. not so hot that it destroys the column packing).
Advantages of HPLC • Speed (minutes) • High resolution • Sensitivity (ng to fg) • Reproducibility of +/- 1% • Accuracy• Automation Disadvantages of HPLC • Cost • Complexity • Low sensitivity for some compounds • Irreversibly adsorbed compounds not detected • Co-elution difficult to detect Isaac Kiplagat, MSc
High performance liquid chromatography (HPLC) is used to separate and identify compounds based on their polarity. The advantages of HPLC is that produces results within a few minutes. The results are high resolution and easily reproduced and tested.
That mainly depends on what kind of L.C. (Liquid Chromatography) is meant:
It's expensive to buy a GC/MS machine. The tubes you use for each sample are expensive. You need a trained operator. If you don't have your own machine you'll have to send the specimen off to be tested. And it's slower than most other ways of analyzing samples.
The other thing about GC/MS is either an advantage or a disadvantage depending on who you are. GC/MS is very, very accurate. If you smoke weed, being tested on an extremely accurate machine is a disadvantage. If you're trying to catch pot smokers, it's definitely an advantage.
the draw backs is that are that they will loos money
Chromatography can not be used in quantitative analyses and it doesn't allow the separation of complex mixtures. These are the limitations of chromatography.
An advantage of column chromatography is that is has both preparative as well as analytical applications. A disadvantage is the technical skill required to properly set up the column.

There is no such thing as grass chromatography. there is only High Performance Liquid Chromatography, Gas Chomatography, and Paper Chromatography.
Chromatography is the method used to separate a mixture of dyes or inks.

Chromatography is the method used to separate a mixture of dyes or inks.
it can be used in everyday life by liquid chromatography, gas chromatography, thin-layer chromatographyand paper chromatography.
chromatography seperates substances from an object
MPLC is Medium Pressure Liquid Chromatography.
No, they are different techniques.
Journal of Chromatography A was created in 1958.
Biomedical Chromatography was created in 1986.
