they would cause flicker and consequent imprecision, and generally the bulk of droplets are of the order
of 2-5 µm in diameter when the aerosol exits the spray chamber. One consequence of this is that the
sample transport system is inefficient, of the order of 1-2%. On exiting the spray chamber, the gas
stream containing the aerosol is directed through the injector tube which forms part of the quartz torch,
and thence into the base of the ICP. The injector tube has an internal diameter of ca 2 mm, so the 0.6-
