β¦ Synopsis
A Pirkle-concept chiral stationary phase (CSP) derived from N-(1-naphthy1)leucine was evaluated for developing methods to reduce analysis times and investigating techniques in the rapid screening of a variety of chiral compounds over a given chiral selector. The effects of reduced column lengths and elevated temperatures were studied to shorten analysis times.

Optical resolution on the analytical scale of a number of racemic pharmaceuticals and some other biologically active compounds has been studied using immobilized bovine serum albumin (BSA) as the stationary phase. For some of the compounds the elution order was determined by the use of optically enr
## Abstract Liquid chromatography of polymers is traditionally a slow technique with analysis times of typically 30 min per sample. For the application of liquid chromatographic techniques to combinatorial materials research the analysis time per sample must be reduced considerably. Analysis time i
## Abstract Cellulose tris(3,5βdimethylphenylcarbamate) (CDMPC) was synthesized and coated on aminopropylsilica to prepare a chiral stationary phase (CSP). HPLC methods were developed for the direct enantioseparation of 12 chiral triazole compounds on the CSP. The separations were made using normal
