Can the Existing Ion Source on the X500R QTOF System Be Converted to APCI?

For research use only. Not for use in diagnostic procedures.

Answer

The source on the X500R QTOF System can be used in atmospheric-pressure chemical ionization (APCI) mode, but a different probe with a twin electrode must be installed. In addition, a different APCI tuning solution must be used that is available for purchase from SCIEX (part number 5042915; see table below for ordering information).

The APCI probe (part number 5057681) is shipped when the instrument is shipped, so it should already be on-hand. But it is available for purchase separately if needed. (See below for a picture of the probe.)
