Isothermal Kováts retention indices may be used in GC for identification purposes, but they are also useful in characterisation of stationary phases and for studying structural and physico-chemical properties of both the analyte and the stationary phase. They are currently reported as whole numbers
On the other hand, nitrofluoren-9-ones are n-acids and form charge transfer complexes with polyalkylbenzenes (n-bases). Alumina supports are basic. Acid-base interaction (interaction between acid and base) can be considered when separation is performed on an alumina plate. The order of strength of n
## Abstract __n__‐Alkanes and fatty acid methyl esters have been chromatographed on four capillary columns of different polarity (LM‐1 (100% polydimethylsiloxane), CB‐225 (25% cyanopropyl, 25% phenyl polysiloxane), LM‐100 (immobilized polyethylene glycol), and BPX‐70 (70% cyanopropyl polysiloxane))
As part of our effort at defining a set of standard stationary phases for gas chromatography we have previously reported specific retention volumes Vt [l] and retention indices I [2] of high accuracy [3-61 for upwards of 60 hydrocarbon solutes with poly(dimethylsi1oxane) solvents (PDMS), including O
