Excellent Chromatographic Performance
- High capacity allows for the analysis of low-level analytes while maintaining excellent peak shape and for the injection of complex matrices without overloading the column.
- Four major quaternary ammonium cationic polar pesticides (chlormequat, mepiquat, paraquat, and diquat) were rapidly separated at trace levels from a high ionic strength matrix using an MSA gradient.
- Other cationic pesticides of interest were also separated, including diethanolamine, triethanolamine, NN-dimethylhydrazine, trimethylsulfonium, morpholine, melamine, streptomycin, and nereistoxin.
Designed for IC-MS/MS applications
- Complete resolution of similar mass species such as paraquat and diquat.
- Available in microbore formats compatible with MS flow rates.
- Selectivity allows matrix ions to be diverted to waste, resulting in a cleaner MS source.
- Compatible with solvents (up to 100% acetonitrile and 20% isopropanol).
- Fast analysis of cationic polar pesticides in food, beverage, and environmental water samples.
For use with high pressure IC systems
A high pressure IC system (such as the Scientific™ Dionex™ ICS-6000 HPIC System or Thermo Scientific™ Dionex™ Integrion™ HPIC System) is required to operate this column under standard conditions.
