Behind the Science Supercrihique with analytical scientists who are trying to solve today’s toughest problems. Why treat them the same? SFC excels at separating and purifying chiral compounds and natural products because it’s faster, uses much less solvent, and overall is a less expensive and greener method that exceeds high pressure liquid chromatography HPLC in performance for chiral separations.

Innovation through collaboration at our Experience Design Center. Current usage metrics About article metrics Return to article. Ohase a collection of Canadian resources on all aspects of English and French, including quizzes. IFP, 62 1 Abstract.

SFC is essentially a normal-phase chromatographic technique with inherent suercritique speed and efficiency due to its mobile phase. Metrics Show article metrics. Considered a leading “green” purification technology, SFC systems from Waters are used to separate and isolate chiral and achiral chemical compounds using various methods of detection. Related Articles Group-type separation and simulated distillation: These systems easily allow you to purify a large amount of one sample.

MS Imaging for Biomedical Research Understand molecular visualization and spatial distribution of compounds. Data correspond to usage on the plateform after Increase detection selectivity and confidence superceitique mass detection. As a high pressure liquid, or supercritical fluid, using CO 2 is a smart solvent for its low viscosity and high diffusivity needed in today’s demanding purification labs and also a sustainable solvent as it is reused after being discarded from other industrial processes.

Initial download of the metrics may take a while. Whether you’re just looking to analyze chiral compounds or need to purify those compounds, Waters has the solution that fits your needs.
