equally in size, highly flexible, quantitative even in the qualitative range.

On one page is the whole result of a chromatographic analysis concentrated as a figure with two axes: The y-axis is the QUANTITY axis giving area-%, weight-%, or mole-% in a linear or a logarithmic scale depending on the concentration range.
The X-axis is the QUALITY scale given in retention time, k-data, or index values again on a linear or logarithmic scale - see figure 1 below.

We use theoretical concepts which were developed at IfC in the last 30 years combining GC with HPLC with Planar Chromatography for most important practical reasons. It is not important how the chromatographer gets information. ONLY important is that he gets correct and complete information as all decisions based on his data are only as correct and complete as the results of his most often vital work.

Browse our Web site for more information about other - and truly better - modes to check for the quality of a column, capillary, plate. And how to check the accuracy of sample taking - sample giving - quantitation. Finally the complete and correct evaluation as well as critical comparison in gas chromatography, high pressure column liquid chromatography and high performance planar chromatography is of fundamental importance and seldom done the full range possible. Too often details are overlooked which count or may be the answer for solving an analytical problem.
 

We have developed in hard years of global check outs by our many thousand course visitors new methods or tools for quality control widely unknown in the standard literature like the “Error Detector sf4”. It finds systematic errors by simple mathematical statistics. Don’t worry: it is very easy to use “sf4” if some computer power and some specific software is available.

Figure 1 chromatogram comparison, new look. The identification run (the upside down line) represents saturated normal hydrocarbons (normal alkanes) from C₁₄ to C₃₂.  See examples for GC analyses with wide ranging quantity and quality values under  “LOG-LOG” and the basis of the whole concept under “new look” .

To make life easier for you in this hard field of ERRORS in one of the most interesting and most powerful analytical techniques CHROMATOGRAPHY we added a “where is” and “what is” page in alphabetical order of key words. Just click the X in front of the keyword you searched for and found. It will navigate you immediately to the ANSWER.

You may click ---> HERE to reach this ”where is” page.To reach the MAIN HELP PAGE named “we can help” click here on --->   HELP.

It is our policy to respect the privacy of individuals who visit the Site or provide comments to us.

Institute for Chromatography has a strict policy for handling chromatographers information. The information you may provide to Institute for Chromatography is confidential and protected to the fullest extent possible. Institute for Chromatography will not disclose or distribute your information to third parties without prior written consent by you. This is also the main reason why we DO NOT have an open FORUM, although the web title “interchromforum.com” could sound like that.
However in the section FAQ you will find your impact if IfC gets it written with the key sentence: “please make this public as asked question” and give an answer together with your eMail address. Your address is available exclusively to us - no one else gets it for whatever it may be wanted.
The author will do his best to handle the problem.
This site does NOT offer down loads of chromatography software nor has any advertisement for sales but who insists to get detailed technical and cost information is asked to use e-Mail - see in CONTACT us.

You may try the German sister site of interchromforum.com, which contains latest papers given in January 2006 as a PowerPoint presentation. Unfortunately ppt-files need a longer loading time but select
                                       www.institut-f-chromatographie.de
from where you can easily return to this main site. But have a look into the IfC-News there (in German)

The very latest NEWS: IfC has developed MPLC, the Micro Planar Liquid Chromatography. We will report about the most important details of this new very economical and ecological technique for fast comparison analysis probably later in 2007.

Thanks

to all of the hundreds of chromatography colleagues from

Germany, Slovenia, USA, Russian Federation, Belgium, The Netherlands, Hungary, United Kingdom, Sweden, Swizzerland, Canada, South Africa, Italy, Poland, Chile, Argentina, Brasilia....,
who helped me by close cooperation and years of friendly qualified discussion for understanding, doing and teaching chromatography-
