These options are global and will be always be applied to the instrument.

Enable Polychromator Boost Purge on Connection

  1. Open ICP Expert.
  2. Click File > Options > Instrument.
  3. Select or deselect to either turn on or off the Polychromator Boost purge when the instrument and ICP Expert software are connected.

The Polychromator Boost is typically used if analyzing wavelengths below 189 nm. If the instrument was turned on after more than a few hours of being unpowered the polychromator can take several hours to stabilize the temperature and to purge.

Plasma Auto-extinguish Idle Timeout

  1. Open ICP Expert.
  2. Click File > Options > Instrument.
  3. Select to enable this feature and then enter the length of time in minutes for the instrument to be idle before the plasma is automatically turned off.

Enable Neb Alert

Blocked nebulizers are the source of many instrument performance issues including loss of sensitivity and poor precision, especially when running organics, high solids, or high salt concentration solutions. Neb Alert will monitor the nebulizer pressure and alert you if the pressure moves out of the set range, indicating a potentially blocked nebulizer.

It is recommended to set the upper and lower limits to those corresponding with the typical operating range of the nebulizer. When back pressure increases, a blockage is suspected and the nebulizer should be evaluated. When pressure decreases, a leakage is suspected and the gas/sample lines should be inspected. The table below lists the recommended upper and lower limits for the top three most common nebulizers.

Nebulizer

Lower Limit

Upper Limit

Seaspray

225 kpa

315 kpa

OneNeb 2

180 kpa

250 kpa

Conikal

225 kpa

315 kpa

To Enable Neb Alert

  1. Open ICP Expert.
  2. Click File > Options > Instrument.
  3. Select Neb Alert.
  4. Enter the lower and upper pressure limits in kPa.
  5. Select 'Stop analysis if pressure falls outside limits' if desired. It is recommended to select this to be notified of a potential blocked nebulizer before it happens and to avoid ruined analysis and torch melts.

Enable Reminders on Plasma Ignition

  1. Open ICP Expert.
  2. Click File > Options > Instrument.
