The NPD firmware in this GC (A.01.08 or higher) is
considerably different from that in earlier versions and from
the 6890 firmware. Major changes are:
• Equilibration time parameter has been removed.
• Adjust Offset feature has been changed.
• Auto Adjust on/off has been added.
• Dry Mode has been added.
• Blos/ceramic bead selector has been added.
We strongly recommend that you allow the firmware to
perform Auto Adjust and set the Bead Voltage.
This discussion assumes that the following
firmware/software is installed:

Software/firmware with numbers less than shown in the
table can cause reduced bead lifetime. See the Agilent web
site (www.agilent.com) for firmware and software updates.
The NPD passes sample and carrier through a hydrogen/air
plasma. A heated ceramic or glass source, called the bead, is just
above the jet. The low hydrogen/air ratio cannot sustain a flame,
