Hi! it is me, Nayi, welcome to my blog again! 

This time I’m going to talk about a theme very interesting and important for some careers like it is for mine, Chemistry and Pharmacy: “the Chromatography”

The chromatography is a technique to separate different compounds from a mixture, in the case of my career analyzes the compounds of each drug. Also this technique is used for analysis of drugs in biological fluids such as blood, urine, etc., also can be used to perform quality control of manufactured chemicals and pharmaceuticals. In other careers like food engineering this method can be used to determine inorganic cations in food (like food diet low in sodium) and in urine samples.

There are numerous types of chromatography; one of them is the high performance liquid chromatography (HPLC). This is one of the best methods to separate because is very sensibility, is stable, has a linear response in a wide range and take short time to give an answer about the mixture. But one of the disadvantages is the price, the columns are very expensive, it is for this reason that we must handle them with great care.

That's a bit of what I can tell you about this technique. This works with very small molecules

See you!
