Graphite is all around us. The mineral can be used to accessorize as diamonds, write in school as a pencil, and was even used to write the drafts of this Continue Reading
What is Microelution and What are the Best Strategies When Using It?
Microelution Solid Phase Extraction(SPE) is essentially miniaturized SPE. The technique is ideal for analysts that have small or limited sample volumes or for those that want to save time by Continue Reading
Technical Tip: Bulk HPLC Sorbent Storage and Cleaning for Reuse
In the spirit of frugality, process chromatographers often want to save and store their media for future use. There are steps one can take to store bulk resins for short term and long term use, though it’s worth noting that the media will not last forever.
Poor Sample Recovery? You May Be Over-Drying
For most reversed-phase solid phase extraction applications using a silica-based SPE media, cartridges are initially conditioned using an organic solvent such as methanol, followed by rinsing with water or a buffer.
Technical Tip: Optimizing Wash and Elution Protocols in SPE Method Development
Scientists aren’t perfect. Nobody is. In our Technical Tips, we can solve your most debilitating issues—from mechanics to methodology—together.
