Whether you’re just looking to analyze chiral compounds or chromatogralhie to purify those compounds, Waters has the solution that fits your needs. Metrics Show article metrics. 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 phasse greener method that exceeds high pressure liquid chromatography HPLC in performance for chiral separations.

As a high pressure liquid, or supercritical supedcritique, 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.

Thus, SFC could be the tool chromatogrqphie choice for better determination of conversion in heavy petroleum-fraction processing. Once the optimal mobile phase and stationary phase are determined from screening, the method can be easily scaled for purification on the same system. Initial download of the metrics may take a while. Blogging About What’s Possible Read and follow the Waters blog for insights on how to use — and how customers use — our technologies, including Empower 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.

IFP, 62 1 Abstract. Through a calibration curve relating the boiling point of normal paraffins to their elution temperature or retention time, simdist provides the hydrocarbon distribution of the sample in weight percent versus the boiling range of the fraction.
