Good separation of quaternary surfactants by HPLC with suppressed conductivity detection
Instrument Type: HPLCThe Thermo Scientific HPLC system is applied for the analysis of quaternary surfactants. The separation is performed on a Thermo Scientific Acclaim Surfactant column, with suppressed conductivity detection.
Quaternary surfactant analysis of a cosmetic formulation using HPLC-CAD
Instrument Type: HPLC-CADThis method provides an effective analysis of quaternary surfactants in a cosmetic formulation using a Thermo Scientific Dionex UltiMate 3000 HPLC system with charged aerosol detection (CAD). A Thermo Scientific Acclaim Surfactant Plus column is used, which provides improved results as this group of surfactants tends to tail on conventional silica-based reversed-phase columns. The Thermo Scientific Corona charged aerosol detector is an effective choice since the two active ingredients in this formulation are unsuited to UV detection.
High resolution analysis of the major benzalkonium homologs in nasal spray using HPLC-CAD
Instrument Type: HPLC-CADThe Thermo Scientific UltiMate 3000 HPLC system is applied for the analysis benzalkonium in nasal spray. The separation is performed using a Thermo Scientific Acclaim Surfactant Plus column, with charged aerosol detection.
Simultaneous separation of cationic, nonionic, amphoteric and anionic surfactants
Instrument Type: HPLC-CADThe Thermo Scientific UltiMate 3000 RSLC system is applied for the analysis of cationic, nonionic, amphoteric and anionic surfactants. The separation is performed using a Thermo Scientific Acclaim Surfactant Plus column, with charged aerosol detection. The Thermo Scientific Acclaim Surfactant Plus column, based on novel mixed mode chromatography technology and advanced surface chemistry, provides both reversed-phase and anion-exchange retention mechanisms.
