The GTA viewing/fume extraction accessory is an optional addition
to your Agilent AA instrument and can be used in conjunction with
the mirror or the Tube-CAM to give you further control over the
alignment of the graphite tube and PSD.
NOTE
The GTA viewing/fume extraction accessory is compatible with Agilent 280 AA,
240 AA and 140 AA instruments only.
The GTA viewing/fume extraction accessory has three components:
A mirror to allow you to view the workhead sample introduction
port and simplify the alignment of the dispensing capillary.
A light to illuminate the workhead for easier viewing of the
graphite tube when aligning the PSD or when viewing using the
optional Tube-CAM.
An extraction port which can be connected to the instrument
flue, enabling efficient removal of fumes and exhaust gases from
the furnace during operation.
The GTA viewing/fume extraction accessory can be used with
graphite furnace operation on either a Flame or Zeeman instrument.
