New parts like liners, O-rings, and inlet seals can carry contaminants that cause interfering peaks and high background noise. Don’t be tempted to skip conditioning the inlet after replacing these parts; it’s an easy, effective way to drive off contaminants and prevent problems during analysis.
Adding salt to your coffee may not taste as nice as pumpkin spice, but salt is a great way to shorten the SPME extraction time of just about any matrix for headspace VOC analysis. Here’s how the power of salt reduced the time it took our freshly brewed sample to reach equilibrium by 60%.
Looking for pharmaceuticals in fish or carcinogens in dried tea? These are just a few examples of how the QuEChERS approach has been adapted to meet different analytical challenges. Watch this quick video and learn what modifications work best for different applications.
Hydrophobic interaction liquid chromatography (HILIC) is a powerful LC technique that uses polar stationary phases and high-organic initial mobile phases to retain and resolve challenging polar analytes. Join us for this first video in a new series exploring the HILIC realm.
