Agilent 6495 Instrument

Weck laboratories has two LCMS and two GCMS triple quadupole mass spectrometers. We are retiring our original LCMS instrument (purchased in April 2005) and replacing it with the latest offering from Agilent Technologies, the 6495 LCMS triple quadrupole mass spectrometer, for use with applications requiring the highest sensitivity and robustness. This system is designed for both routine laboratory analysis and for the most challenging quantitation in environmental and food safety applications.

N-N-bis(2- hydroxyethyl)glycineAs a degradation product of alkanolamine and alkylalkanolamine solutions, , also known as bicine, is commonly found in gas treating amine solutions. The proposed pathways for the formation of bicine in amine solutions are all from alkanolamines and alkylalkanolamines such as DEA and MDEA. For example, some possible pathways are by either reacting DEA with glyoxal or through direct oxidation of DEA, MDEA, or TEA by O2 or SO2. Studies have shown...
