Analytical catalogue selection

Since a large proportion of refrigeration and air-conditioning equipment will be bought on the basis of catalogue data, an analytical approach should be adopted to ensure correct selection. The principles to be applied are those of value analysis — to start with the basic need and no preconceived method, to consider all the different methods of satisfying the need, and to evaluate each of these objectively before moving towards a choice. 

It would be easier to describe those classes of compounds not normally separated by RPLC than to catalogue the applications to which RPLC has been turned. Applications for reversed phase can be found in virtually every area of analysis and are reviewed regularly in the journal Analytical Chemistry. RPLC has not been in general use for the analysis of inorganic ions, which are readily separated by ion exchange chromatography polysaccharides, which tend to be too hydrophilic to separate by RPLC polynucleotides, which tend to adsorb irreversibly to the reversed phase packing and compounds which are so hydrophobic that reversed phase offers little selectivity.
