Your Autosampler Can Make Mixtures and Calibration Standards
Merlin K. L. Bicking, PhD, President and Senior Analytical Scientist, ACCTA, Inc.
We have automated or improved nearly every step in most chromatography methods, except for the preparation of calibration standards. High precision and accuracy methods still require Class A pipets and volumetric flasks, and large volumes of high purity solvents. This presentation will describe a simple procedure that uses a typical HPLC autosampler to prepare single or as multi-component mixtures of calibration standards at multiple levels. The method is most efficient when you have the ability to program the autosampler directly, but there are simple variations that can be developed without such programming. Multiple applications will be shown that demonstrate the ability to prepare standards that match manual preparations. This on-demand procedure has been successfully validated for GMP use and is an excellent alternative for high-cost standards.
