Click here Featured App Note Measurement of Electrophoretic Mobility of Coated Nanoparticles Using EAF4 The EAF4 system was used to measure the electrophoretic mobility and zeta potential of 50 nm Ag nanoparticles (AgNPs) coated with three different coating materials.   GC Hydrocarbon Analysis with Agilent 8890 GC Analysis of monocyclic aromatic hydrocarbons in accordance with ASTM method D7504 with the Agilent 8890 GC and DB-Heaver Wax columns. Analyses of PFOS and PFOA Precursors in Textile Products To address environmental concerns that may arise from PFOS and PFOA, two GC–MS methods—PCI-SIM and EI-MRM—were optimized for detection of PFOS and PFOA precursors.   LC Fast and Easy Injection of Large Sample Volumes in Preparative HPLC The 1290 Infinity II Preparative Binary Pump is far more than just a gradient pump. An integrated solvent valve enables high-speed injections directly onto the column. Eliminate the Impact of Instrument-Related PFAS Interferences Using a PFAS delay column is an effective way to separate target PFAS in samples from interferences caused by PFAS contamination in the LC system. Is Your Water Causing Ghost Peaks in Your HPLC? The quality of your solvent is critical to your HPLC analysis; trace contaminants can give you "ghost" or "phantom peaks". Challenging Analysis of Amyloid β Proteins Amyloid β proteins are highly hydrophobic and can form aggregates. Analysis of four Aβ using YMC-Triart Bio C4 with larger pore and lower hydrophobicity is presented. LC Analysis of Energy Drinks Eight major ingredients were successfully separated from commercial energy drinks using an ACE C18-Amide reversed-phase column and VWR Hitachi Chromaster HPLC system.   Sample Prep Automated SPE of Perfluorinated Compounds (PFCs) Learn more about automating the isolation of PFCs from tap water prior to their analysis by LC–MS systems, with results showing good reproducibility and reduced time. Enhanced Aroma Profiling of Vodka This study shows the advantages of automated immersive sorptive extraction for the GC–MS analysis of a wide range of aroma compounds in vodka. Determination of Mycotoxin Residues in Grain This application note details two UCT sample preparation approaches (SPE and QuEChERS) that can be used for the extraction and clean-up of mycotoxins from grain-based food.   LC–MS Integration of Cubis® II Premium Balances into STARLIMS™ Sartorius and Abbott Informatics have developed a complete computerized solution for a professional integration of Sartorius Cubis II lab balances into STARLIMS. Pesticide Solubility SPEX CertiPrep has compiled the common properties and solubilities for the most common pesticide groups in order to aid in your pesticide analysis.
