Liquid Chromatography Mass Spectrometry LCMS-A11 features a flow rate range of 1 to 4000 µL/min, adjustable in 1.0 µL/min steps for precise control. It uses a triple quadrupole tandem mass spectrometer for accurate analysis. The system supports full loop, semi-loop, and microliter injection modes to suit various sample needs. It is equipped with E Spray biorthogonal electrospray ion source technology, offering high ionic yield and strong resistance to matrix effects. Our liquid chromatography mass spectrometry delivers high sensitivity in detecting sulfonamides in pork, pesticides in water, environmental pollutants, neonatal diseases, and vitamin D in serum.
