The Revival of Supercritical Fluid Chromatography in Pharmaceutical Analysis

There has been a great renewal of interest in supercritical fluid chromatography (SFC) as a performing analytical tool for various types of applications recently. SFC is particularly suitable for pharmaceutical analysis, where it is required to have separation methods offering high throughput, elevated efficiency, and, importantly, sensitivity for the determination of drugs in various matrices, such as drug formulation and biological fluids. However, SFC has also been used for other applications, including food analysis, polymer analysis, and environmental analysis, as reported in a recent review.

Ultra-Fast Separations of Pharmaceutical Compounds with 10 mm Columns Packed with Sub-2 µm Particles

Very short columns filled with 1.9 µm particles were evaluated for the ultra-fast analysis of pharmaceutical formulations. Local anæsthetic, mydriatic and anti-hypertensive agents were chosen as analytes and a method was developed and validated for each of these substances, according to ICH guidelines. Excellent quantitative performance was obtained using an optimized chromatographic system that reduces the importance of extra-column effects and cuts the analysis time to less than 15 s.

Method Transfer in HPLC

Many HPLC analyses could be performed at lower expenditure. This could involve a combination of reducing the analysis time, reducing the resolution between critical peaks, and lowering the consumption of mobile phase. Successfully optimizing the method in such instances - as well as in situations where it is necessary to transfer the method to another laboratory that lacks the same selection of columns - can save the analyst time and money.
