Detection System Parameters<br />
◗ Dynode Voltage: 15kV (fixed)<br />
◗ Electron Multiplier: 2500 Volts max.<br />
Note:<br />
– Multiplier voltage is a calibrated parameter.<br />
– For best results, the multiplier should not be set manually.<br />
<strong>Troubleshooting</strong>:<br />
No peaks on Classic: Check multiplier voltage<br />
Switch dynode polarity<br />
Check for ions<br />
No peaks on <strong>Deca</strong>/<strong>Duo</strong>: Check Multiplier and Dynode Voltages.<br />
Noisy spectra with heated capillary capped off:<br />
