The software for the mass spectrometer identifies the installed probe and enables the
corresponding user controls. All of the data acquired using the ion source is identified with an
abbreviation representing the probe used to acquire the data (TIS for the TurboIonSpray probe
and HN for the APCI probe).
TurboIonSpray Probe
The TurboIonSpray probe consists of 300 μm outer diameter (o.d.) (0.012 inch) stainless steel
tubing. It is located centrally with the two turbo heaters placed at a 45 degree angle to each
side. Samples introduced through the TurboIonSpray probe are ionized within the tubing, by the
application of high voltage (
IonSpray Voltage
). Then they are nebulized by a jet of hot, dry,
Zero-grade air from the turbo heaters, creating a mist of small, highly-charged droplets. The
