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.

Figure 1 chromatogram comparison, new look. The identification run (the upside down line) represents saturated normal hydrocarbons (normal alkanes) from C₁₄ to C₃₂. Useful for GC analyses with wide ranging quantity and quality values

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 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 - by now only in German. The English version will need some time. The first part of this new site is called ACT = Alternative Chromatography Theory, correcting some serious misconcepts in the classical theory and adding a missing but important part.
