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 A Greener Approach to Analytical and Purification Applications For laboratories overwhelmed with solvent disposal and time-consuming solvent cleanup, supercritical fluid chromatography SFC is a beneficial alternative to purification and analytical applications.

Chromatographie liquide en ph 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. The current usage metrics is available hours after online publication and is updated daily on week days.

Supercritical Fluid Chromatography

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.

MS Imaging for Biomedical Research Understand phsae visualization and spatial distribution of compounds. SFC is essentially a normal-phase chromatographic technique with inherent high speed and efficiency due to its mobile phase. Technique in which the mobile phase fluid is maintained at temperatures somewhat above its critical point.

Increase detection selectivity and confidence using mass detection. The principles of SFC are similar to those of liquid chromatograpjie, however SFC typically uses carbon dioxide as the main mobile phase.

The operating conditions used for simdist are tuned to be in agreement with preparative distillation that gives the True Boiling Point TBP curve.
