Here are some chromatography links that I have found somewhat useful, please add other useful links below. I am especially interested in a useful column comparison site, comparing columns with a standard test mix with chromatograms.

Thanks, Tom! Very useful. For those looking for more basic links (courses, manufacturers, discussion groups), I put one together for the "Getting Started in HPLC" web cours. You can find it at:

http://www.lcresources.com/courses/getting_started/additional%20links.htm

Any other suggestions?

Some more, hope they work:

The biggest links compilation I know (many in spanish), about chromatography and other chemical resources

http://matematicas.udea.edu.co/~carlopez/chromatography/

Hope it helps

I have checked the link I gave, and it has problems. Try

http://matematicas.udea.edu.co/~carlopez/

and then, chromatography

Hi everyone,

I am wondering would you know of some links (method development, trial and error, discussion groups, etc.) that are related to LC-MS instead of just LC?

Thank you!

Try www.lcms.com

any web site is ther were i can find out method fo analysis for formulation s and active drugs by chromatography.

Applications Library and Applications Note Books with printable methods available for different applications:

A good Application-source is:

Thanks, Tom! Quite useful. For those looking for more good sites regarding the new monolithic HPLC column techonology (Chromolith columns) check out the following source which I found very helpful:

Lots of information regarding this technology including applications and literature

Presentation of a new quality of chromatography

Dear Sirs,

I present to your attention:

A new technology of chromatography with pressure programming of the carrier gas has been investigated and for the first in the world been proposed, based on the gradient pressure movement along the column performing the function pressure - location - time and keeping Dp constant at the ends of the chromatographic column during the whole process of analysis. (Russia patent N 1658083 Chromatograph of A.S.Hayrapetyan).

Provision of optional conditions by means of keeping the constancy of the linear rate of an imaginary point - the sample zone undergoing analysis being transferred from the injection point to the chromatographic column outlet, with which a maximum column efficiency ( Hayrapetyan's Effect ) is attained.

The newest technology chromatography - Chromabarography, that protects its flight , at the beginning of XXI century, and retardation at the beginning is baneful not only in sport, but in science and economics as well.

KNOW - HOW and ENGINEERING in the creation of new modifications of CHROMABAROGRAPHY with effective synergism.

Realization of best ideas related with the expansion of the possibilities of CHROMABAROGRAPHY as an alternative to CHROMATHERMOGRAPHY and TEMPERATURE - PROGRAMMED CHROMATOGRAPHY, working out of means for their combined application with a patent defense, joint patenting of new technical solutions with leading firms in USA, Great Britain, Germany, Italy, France, Japan, China, Canada, Russia, the Netherlands, Czechia and others interested in this field.

I would be happy if you considered it convenient to express your opinion
and your interest in concluding a joint patenting in the countries chosen by you.

Awaiting forward to your response,

Respectfully,

Aram Hayrapetyan.

NIST SRM 870:

Hi there
Could someone add any link on GC or HPLC softwares

http://www.zirchrom.com
Chromatographers Enzyclopedia
contains some files about solvents,buffers and for those working with acidic or basic compounds
a table of dissociation constants.

I'm searching for some links about HPLC columns and their characteristics (eg %carbon, selectivity,...).

There exists an expensive commercial data bank (comparison of more than 60 HPLC-Columns): info@kromidas.de

PETER

The next Journal of Separation Science will have some articles dedicated to the selectivity of stationary phases. I have a collection of data. Contact me!

Hi Anon 03-02-21,
for physical properties vendors are the best place to look. some mor phases are listet here:
http://www.phenomenex.com/Phen/Doc/group%20files/zhtec374.pdf
Column comparison data depends very much on how you define seletivity. Again vendors that sell different brands are useful:
http://www.alltechweb.com/Literature/catalog500/374.pdf and
http://www.alltechweb.com/Literature/catalog500/375.pdf or
http://www.mac-mod.com/pdf/CCGuide.pdf or the waters selectivity chart:
http://www.forumsci.co.il/HPLC/columns.pdf (there is somewhere else a version that includes YMC-Columns as well)
Hope that halps
