The most commonly used stationary phases are shown Figure 2. Tony Taylor and Crawford Scientific have several online courses and they usually conduct webcast and tutorials on various topics http: Hardy, The University of Akron: In HPLC the 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.
When ionizable or ionic analytes are present, other additives such as buffers or ion pairing reagents can be added to the mobile phase to control retention and reproducibility. Chromatography An introduction given by the encyclopedia Britannica.

Calculating the pH of a Strong Acid Solution The page includes the responses to questions presented to the forum. Methods and Techniques The Nest Group: 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.

Effect of Buffers on the Analysis of Basic Analytes Reversed phase HPLC successfully separates both polar and nonpolar neutral molecules with molecular weights below Daltons. EU agrees on maximum cadmium level in fertilisers.
The IUPAC Definition of Chromatography “Chromatography is a physical method of separation, in which the components to be separated are distributed between two phases, one of which is stationary whilst the other moves in a definite direction”. An online resource for the separation science community provided by Wiley.
