✦ Synopsis
A newly commercialized fluorinated silica, Fluofix 120N
[1H71H,2H,2H,3H,3H-tridecafluord4,4-dimethy1hepty1)si1y1 bonded spherical microporous silica gel], was used as a packing material for supercritical fluid chromatography (SFC). The performance and stability of this fluorinated phase were examined under different experimental conditions. The SFC behavior of this phase was compared with a conventional C,, bonded reversed phase. The excellent separation power of the Fluofix 120N phase for fluorinated compounds was demonstrated by high-resolution separations of different perfluorinated polymers.

A versatile system with a slurry-packed capillary column was developed for supercritical fluid chromatography, which is capable of programming both inlet and outlet pressure independently, as well as using a restrictor to apply back pressure. This system revealed the relationships between pressure d

## Abstract Selective stationary phases are of crucial importance in packed column supercritical fluid chromatography (SFC), and a potentially powerful selective stationary phase, silica‐bonded 8‐quinolinol, has been evaluated. Its performance was compared with that of an aminopropyl modified silic
Strongly basic polyethylenimines (PEI) were coated on both untreated and diol-bonded silica particles. The resultant basic surface was found suitable for the separation of strongly basic alkylamines such as a-phenylethylamines with a pK, of ca. 4, under supercritical fluid chromatography (SFC) condi
