Preliminary evaluation of a standard reference material for chiral stationary phases used in liquid and supercritical fluid chromatography.
The applicability of a new Standard Reference Material (SRM) for the evaluation of chiral stationary phase (CSP) performance was demonstrated by utilizing the SRM to characterize the chromatographic behavior of eight commercially available CSPs in liquid and supercritical fluid chromatography. The SRM consists of five ethanolic solutions, each containing one chiral compound. These test mixtures can be used to assess changes in column performance over time and to evaluate lot-to-lot variability in column manufacturing. The SRM was also used to probe the effect of various parameters on column performance.
