By Scott Krepich, Food and Environmental Application Scientist Hydrophilic Interaction Chromatography (HILIC) is a variant of normal-phase liquid chromatography that partly overlaps with other chromatographic applications such as ion-chromatography and Continue Reading
How many scientists could honestly say “no” to less variability and increased reliability? Yet, time and time again, we see scientists who are content with Liquid-Liquid Extraction (LLE) as the Continue Reading
In the first GC columns, gas chromatography phases were simply coated onto the column. This was mostly the case with packed columns, but also the same with the very first capillary columns. Injecting water onto these phases dissolved the phase and caused the phase to elute from the columns.
When visiting scientists in their labs, Field Applications Scientist, Danielle Moore, is frequently asked about tuning their analytes on a mass spectrometer. More specifically, why it is so important to Continue Reading
Guest Author: Ramkumar Dhandapani, Ph.D.- Gas Chromatography Technical Manager In gas chromatography (GC), the separation of analytes is achieved primarily based on boiling point (Van der Waal’s interaction), although other intermolecular Continue Reading
Part 2: Optimizing EPA Method 610 Guest Author: Dr. Jeff Layne Welcome back! In the last article, we looked at the EPA method for the analysis of polynuclear aromatic hydrocarbons—EPA Method Continue Reading
