Institute for Chromatography has been serving chromatographers from over 55 countries since 1972 in analytical CHROMATOGRAPHY. We specialized in correct, precise, affordable analytical data by GC, HPLC, HPTLC / µ-PLC. Our top speciality is “finding and reducing qualitative and quantitative systematic errors”, a field about which only a very few experts are willing to work and report. However just the systematic error is most critical in all chromatography areas.
And this is one topic of this virtual Institute for Chromatography: Detection and Reduction of Systematic Errors. The other is: Micro Planar Liquid chromatography as the first “green” TLC technique: optimally small, very economical, very accurate and precise, as far as possible free from “bad solvents”. If you want to see a video: information is HERE .
We add proposals for elegant problem solutions, forgotten, never used or just not understood but important and most helpful details of gas-, column-liquid and thin-layer chromatography “secrets”. Now we are free to talk about.... (and invite you, to think about or just to do it. It will work).

The international language of the chromatographers family are CHROMATOGRAMS but this site shows no one single classical elution chromatogram.
We feature a NEW look onto elution chromatograms: completely quantitative, covering the whole range of concentration,

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 50 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.

Thanks to all of the hundreds of chromatography colleagues from
Germany, Slovenia, USA, Russian Federation, Belgium, The Netherlands, Hungary, United Kingdom, Sweden, Switzerland, 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-

You may try the German sister site of interchromforum.com, which contains latest papers given in as a PowerPoint presentation. Unfortunately ppt/pdf -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)

NEWS: are found there under IfC-News
www.planar-chromatography-by-kaiser.com is now as Internet-only book available in the internet.
The latest paper of the author given at the 8th BALATON Symposium on High-Performance Separation Methods and the 15th International Symposium on Separation Sciences Siofok (Hungary) Sep. 1. - 4., 2009 is now available here . Title: Drastic Reduction of the Structure Error in Quantitative Planar Chromatography. The latest issue of the OpenAccess book on µ-PLC includes first pages on water trace analysis - with unexpected results about fluorescing traces which chemisorb on silica gel of the plate layer.
There is a new critical paper in this site - see “Paper 2010”. May be you also do not like any method
(over)regulation. So you may agree with the authors proposal given in this paper (ppt/pdf type).
I have started the new site www.internet-chromatography.com - with some latest contributions of chromatographer colleagues in English, by otherwise by now mainly in German language. The English version will need some time. The first part of this new site is called ACT = Alternative Chromatography Theory, correcting some serious miss concepts in the classical theory and adding a missing but important part.
In www.internet-chromatography.com you find information about a new program
“Calibration Line Mathematics, Polynomial Interpolation and Graphical Statistics”,
written in PureBasics. This is a quite young program language with outstanding characteristics. It produces fast running programs with utmost mathematical accuracy in a remarkably small code of - as an for example: 20 KB [purebasic] versus 25 MB [KBasic] in equal tasks. It works very close to an assembler level but is fundamentally modern basic. It uses quite some C ( C++) characteristics. You may have a look into www.purebasic.com and you may be able to learn purebasic programming in a few months if you are a newcomer to programming chromatography tasks because of a very well done programmers support by on-line help.
In the Polynomial Interpolation program “PI-rek-D” (german) and “PI-rek-E” (english)” it is easy to avoid overloaded MOUSE action based on so called “industrial standard” programming but if a ‘graphics close -’ or a ‘data file - call’ or a ‘print report’ needs mouse clicks, the mouse is there with everything you are familiar with in MS Windows 2000, Windows XP or Windows 7.
The first ‘INFO VIDEO’ just for information and for nothing to buy or pay is in easy reach. No language problem because there is no word to hear. I invite you to start publishing detailed chromatography information and ‘tricks’, ‘tips’ via VIDEO !
Clicking the LINK below brings you to the first (mini) VIDEO about how µ-PLC, a most powerful COMPARE analysis technique, works. You need the proper plug-ins to see the video. It works at best under Google Chrome as browser in latest MAC’s, under WIN XP or WIN 7.
The 4.5 minutes VIDEO (over 7500 jpg’s are crunched from 150 to < 20 MB) is limited sharp and done under critical conditions of minimized light because of the heat effect on a HPTLC plate. The easiest way to have a look onto this short (soundless) video is a click onto this LINK:
