a Tube with an O.D. of 1/8 inches and an I.D. of 2.18 mm, and b tube with an O.D. of 1.61 mm, and an I.D. of 1.25 mm. The end of the ion transfer tube was connected to the orifice of the mass spectrometer. A heater block was attached to the tube. c Comparison of NaI cluster ion signal intensities. L and S refer to the ion transfer tubes in (a) and (b), respectively, and the numbers indicate the temperature of the tube.
