Agilent Jet Stream Technology enhances analyte desolvation by
collimating the nebulizer spray and creating a dramatically
"brighter signal." The addition of a collinear, concentric,
super-heated nitrogen sheath gas (Figure 22) to the inlet
assembly significantly improves ion drying from the
electrospray plume and leads to increased mass spectrometer
signal to noise allowing the triple quadrupole to surpass the
femtogram limit of detection.
