Are You Optimizing Your Solid-Phase Extraction? (Part 2)
I have dedicated this issue to answering the questions that we posed regarding the solid-phase extraction of propranolol from a plasma extract.
As promised in the last instalment I have dedicated this issue to answering the questions that we posed regarding the solid-phase extraction of propranolol from a plasma extract. This builds on the information given last time on choosing sorbents and protocol solvents for optimum selectivity.
Identifying and Rectifying the Misuse of Retention Indices in GC
December 10th 2024LCGC International spoke to Phil Marriott and Humberto Bizzo about a recent paper they published identifying the incorrect use of retention indices in gas chromatography and how this problem can be rectified in practice.
Overcoming Common Challenges to Determine Residual Impurities Using IC in APIs with Limited Water
December 10th 2024Organic solvents are generally not compatible with ion chromatography (IC) systems. The approach presented here assists the use of organic solvents for sample preparation and provides a mechanism for the removal of the organic solvents from the chromatographic flow path.
