TurboIonSpray Probe Parameters
The following table shows the recommended operating conditions for the TurboIonSpray probe
at three different flow rates. For each flow rate, the flow rate of the gas for the Curtain Gas
interface should be as high as possible. The solvent composition used for optimization was 1:1
water:acetonitrile. These conditions represent a starting point from which to optimize the probe.
Using an iterative process, optimize the parameters using flow injection analysis to achieve the
best signal or signal-to-noise for the compound of interest.

Optimum temperature values depend on the compound and mobile phase composition. Higher aqueous
content requires a higher temperature. Zero (0) means no temperature is applied.
