HI
I am a 11th grade student an I need everyones help on the subject of chromatography. I need to know when it was started how,why,and where. I would like you all to help me list 4 types of chromatography. Please help me!

Type in the word "chromatography" on a search enginge, it's all there

Gas chromatography
Paper chromatography
DNA chromatography

That is all I know! Go to Mr Sketch Ink(The website about chromatography). It is very informative.

Try using the library. Find a book on chromatography or just look in an encyclopedia. Use something that you can reference. The lessons learned in your English comp class should not be forgotten when you enter a science class. Websites like this can be very useful in the right context, but you never know when someone is giving you false information. You should really be wary of this happening since professionals are getting tired of lazy high school students expecting us to do their work for them.

I am very happy when contact with lady or gentle man!
I would like to know Why the ion chromatography be variable after 2 hours mesure anion in tap water samples?
Please teach me how to solve this problem.
Thank you very much.

My name is Rachel
I would like for someone to explain
in simple words what is Chromatography.
how does it work
what is the difference between
gas and thin layer Chromatography.
thanks
my e-mail is oded@kesher-yashir.co.il

The chromatography science was based on mosseley demonstration and the 4 types chromatography are
1.liquid chromatography
2. Gas chromatography
3. Ion -pair chromatography
4. capillary electropoisis

Hi! I'm a 7th grader doing a science fair project on Paper Chromatography. Right now im doing my reach paper it is on the spectrum and properties of a color, and i am totally lost!! if you could give me some info on this it would be great!!
you can email me at soccerstopper36@aol.com

Oh, this is an easy one! Just walk over to your brick and mortar library and pick up an encyclopedia. You will be sure to find at least a couple of good pages explaining this in a concise and easy to understand format. Or, pick up one of those science books like you would find at the "Nature Store" or any major bookstore. These should also be available in the library.

Nothing in life is more valuable and CAN'T be taken away from you, are good research, reasoning, and problem solving skills. Learn them and you will be a very successful person.

can anyone tell me a website on chromatography?


I am in sixth grade and i'm doing this as my science project

Hi, i'm a french student who have to write a report.
The subject is "detecting alcohols in wines and spirits". I would like to know if the chromatography is a good way to do it, and which kind is the best way. if you have any information, could you send me a message on my e-mail cecile_martin_bx@hotmail.com, thanks

Cécile,

Jette un oeil sur ce site : http://www.chem.agilent.com/cag/cabu/cgramfood.htm

Hi Cécile,
the best way to detect alcohols in wine and spitit is gas-chromatography. Due to the high resolution of gc-columns you get a signal for each homologue alcohol. Enzymatic determination of alcohol (like in boehringer-ingelheim kits) gives you only a summary, because the enzyme alcoholdehydrogenase reacts not only with the ethanole but also with methanole and other homologues.
Hope this helps you.

why we need ethanole mhene we extract DNA????? PLEASE HELP ME ..... I CAN'T FIND IT... THANKS
