Setting The Burner Height - PerkinElmer aanalyst 200 User Manual

Setting the Burner Height

When you operate the spectrometer for the first time and every time you have disassembled the burner for
cleaning, you must check and set the burner height. You must perform this procedure to make sure that
the burner head is located just below the radiation beam.
1. Make sure that the burner system is set up properly and that the correct burner head for your intended
analyses is installed.
2. Install a suitable lamp.
Ideally you need a lamp that emits a beam of visible radiation.
3. If not already on, power up the spectrometer. Do Not Ignite The Flame.
4. Hold a piece of white card above the burner head at right angles to the burner slot. Observe the light
spot on the card. Ideally the radiation beam should pass over the length of the burner head and be
approximately centered over the burner slot.

•
If the burner is too high so that it obstructs the radiation beam, lower it with the vertical alignment
control.
•
If the radiation beam is not approximately centered over the burner slot, adjust the burner position
with the horizontal alignment control.
