Chapter 5 Optimizing Instrument Settings
5-66 PerSeptive Biosystems
5
If you cannot obtain the resolution listed for the mass range of
interest, consider the following possible causes:
Laser intensity is too high
Sample oxidized, fresh sample needed
Sample does not ionize well in the matrix
Sample is too dilute or too concentrated
Impurities are suppressing ionization of sample
There are heterogeneous components in the peak
5.4.3.3 Optimizing Guide Wire Voltage%
Start with the .BIC file in which you optimized Delay Time or
Grid Voltage%.
Use the following Guide Wire% settings to optimize resolution:
NOTE: Decreasing Guide Wire% to these suggested values
may decrease signal-to-noise ratio.
