MEKC Separation of Gold Nanoparticles
A researcher from the National University of Kaohsiung (Kaohsiung, Taiwan) used micellar electrokinetic chromatography (MEKC) to preconcentrate and separate gold nanoparticles.
A researcher from the National University of Kaohsiung (Kaohsiung, Taiwan) used micellar electrokinetic chromatography (MEKC) to preconcentrate and separate gold nanoparticles. A reversed electrode polarity stacking mode approach was used for the on-line enhancement and separation. Parameters affecting the separation included the sodium dodecyl sulfate surfactant concentration, salts in the nanoparticle solution, the running electrolyte pH, and the capillary temperature. The researcher obtained enhanced detection sensitivities for the gold nanoparticles compared with those obtained using standard MEKC analysis conditions.

December 20th 2024This collection of technical articles, interviews, and news pieces delves into the latest innovations in LC methods, including advance in high performance liquid chromatography (HPLC), ultrahigh-pressure liquid chromatography (UHPLC), liquid chromatography–mass spectrometry (LC–MS), and multidimensional LC.
Using LC-MS/MS to Measure Testosterone in Dried Blood Spots
December 19th 2024Testosterone measurements are typically performed using serum or plasma, but this presents several logistical challenges, especially for sample collection, storage, and transport. In a recently published article, Yehudah Gruenstein of the University of Miami explored key insights gained from dried blood spot assay validation for testosterone measurement.
