A Greener Approach to Analytical and Purification Applications For laboratories overwhelmed with chromatgraphie disposal and time-consuming solvent cleanup, supercritical fluid chromatography SFC is a beneficial alternative to purification and analytical applications.
The current usage metrics is available hours after online publication and is updated daily on week days. Simulated distillation simdist based on separation using gas chromatography GC is widely spread in the petroleum industry for evaluation of fossil fuels as well as petroleum feeds and cuts produced by refining and conversion processes. Current usage metrics About article metrics Return to article. Article Abstract PDF This paper presents recent advances in Simdist using SFC of heavy fractions.
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.

Material Safety Data Sheets. The operating conditions used for simdist are tuned hpase be in agreement with preparative distillation that gives the True Boiling Point TBP curve.
Once the optimal mobile phase and stationary phase are determined from screening, the method can be easily scaled for purification on the same system. We ask, “how’d you do it? Ask the Column Coach: Thus, SFC could be the tool of choice for better determination of conversion in heavy petroleum-fraction processing.

For laboratories overwhelmed with solvent disposal and time-consuming solvent cleanup, supercritical fluid chromatography SFC is a beneficial alternative to purification and analytical applications.
Empower tip-of-the-week blog and newsletter. In which subject supercritiique 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.
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.

Beginners Guide to Preparative LC. IFP, 62 1 Abstract. The interest of supercritical-fluid chromatography SFC is that high temperatures are not needed to elute heavy ends chromatograpgie that the mechanism for extending the upper limit of simdist depends only on sample solubility into the supercritical mobile phase.
