What is the minimum mass load per cartridge for Sep-Pak tC18 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 37-55 µm (WAT036815)? - WKB223969
Article number: 223969
ENVIRONMENT
- Sep-Pak
- Solid-phase extraction (SPE)
- Sample preparation
- Silica-based packing
- Trifunctionally bonded C18 (tC18)
- Mass load
ANSWER
This needs to be determined experimentally for each analyte.
ADDITIONAL INFORMATION
Due to the wide variety of analyte properties, minimum mass load for any given SPE device must be determined experimentally.
Make serial dilutions of your sample down to and even below the lowest expected concentration.
Then, perform SPE on at least three replicates of each diluted sample to determine %RSD for your recovery.
