NeIon™ Technologies

NeIon™ Products

NeIon™ technologies use specifically designed organo-trifluoroborates compounds to label analytes of interest and improve their detection sensitivities in the negative ion mode in Mass Spectrometry (MS). NeIon™ technologies also offer a way to quantitate trace amounts of analytes of interest.

Organo trifluoroborates are stable, negatively charged molecules that can be used as MS tags.

  • Permanent negative charge (pH independent) unlike –PO3−, –SO3−, –COO− groups (Enhanced sensitivity)
  • Produce (or induce) predictable fragmentation in MS/MS mode (Selectivity)

Negative Mode Analysis

  • Very few MS analyses are performed in negative ion mode
  • Only a handful of molecules are negatively charged
  • Selectively labeling with a negative ion MS tag can significantly enhance (100 to 1000 fold) sensitivity (enhanced signal/noise)
  • To the best of our knowledge, no sensitivity/selectivity enhancing MS tag has been reported for negative ion mode analysis

Positive Ion Mode Analysis

  • Majority of MS analyses are performed in this mode
  • Most of the molecules (small or big) ionize in positive mode
  • High probability of interference and background noise
  • Sensitivity-enhancing mass tags have been developed for positive mode analysis
  • Crowded IP landscape
