A few more types of chromatography can be found in practice like gas and ion-exchange. In short, we can say that the techniques are almost the same in every kind, but their mobile and stationary phase differs. What Is a Chromatogram?
aInject a known quantity of the test gas into the gas chromatograph using a syringe or gas sampler. Determine the area of the peak in the chromatogram corresponding to the gas of interest. Repeat the above measurements with at least three different levels of concentration and prepare a calibrati...

How are DNA sequence chromatograms generated? How is DNA replicated? What is the process and how does this affect the DNA chain? Explain fully how DNA is replicated. How is DNA information transferred to RNA? Describe how the process of DNA transcription occurs. ...
Bio-autography localizes antimicrobial activity on a chromatogram using three approaches: (a) direct bio-autography, where the micro-organism grows directly on the thin-layer-chromatographic (TLC) plate, (b) contact bio-autography, where the antimicrobial compounds are transferred from the TLC plate...
Cloned DNA (cDNA) libraries are produced from the mRNA present in a cell. Complementary DNA sequences can be made and inserted into new cells. These fragments are typically spliced into a plasmid and inserted into a live cell. Knowing the sequence of the plasmid is very helpful in studying ...

Typically the substance comes out of the gas and is absorbed on to a solid or liquid, which is then analyzed by a detector. When the sample is analyzed, the retention time is reported or plotted to create a chromatogram. Standard samples of drugs are run, as well as the urine/blood ...
