Fri Aug 08, Calculating the pH of a Strong Acid Solution Effect of Buffers on the Analysis of Basic Analytes Hi to everyone, one question, does anyone know a good HPLC method development course? Calculating the Molar Concentration Using Triethylamine as a Sacrificial Base 49 In HPLC nplc stationary phase is either a solid, porous, surface active material in small particle form, or a liquid which is coated onto micro-particulate beads of an inert solid support usually silica.

The mobile phase is a liquid that moves through the packed bed of stationary phase in the column under pressure. Alternatively stronger acids and bases have been analyzed alongside hydrophobic analytes using mixed-mode chromatography in recent times.

The Chromatogram shown Figure 3 illustrates the general elution order of hydrophilic and hydrophobic analytes. Objectives At the end of this Section you should be able to: Organizations related to Chromatography Company Database: A C18 or Octadecylsilane ODS column is usually the first choice hpkc method development, although this may differ in certain industries where analytes are chemically very similar little difference in hydrophobicity.


This reference, which was compiled by W. Calculating the pH of a Weak Acid Solution Maybe old fashioned here, but as Manuel from Fawlty Towers once said – what is wrong with “learning from a book When ionizable or ionic analytes are present, other additives such as buffers or ion pairing reagents can be added to the vhromacademy phase to control retention and reproducibility.

There are numerous books that can give you a head start on this topic.

This area contains copies of the lecture presentations associated with Chemical Separation This area contains copies of the lecture presentations associated with Analysis of basic Analytes at Low and Mid pH 48 There are online HPLC courses available http: When working with ionizable analytes the hydrophobicity and, hence, retention characteristics of the analyte will be affected depending on its ionization state ionized or non-ionizedthis will be discussed later in the module.
