Cleaning the MiniPID Lamp
Inspection of the lamp may reveal a layer of contamination on the detection window that presents itself as a
'blue hue.' To check for contamination, hold the lamp in front of a light source and look across the window
surface
Only clean the lamp using our recommended lamp cleaning kit and detailed instructions. To avoid
contaminating the sensor and affecting accuracy, do not touch the lamp window with bare fingers. You may
touch the lamp body with clean fingers.
MiniPID lamp cleaning kit A-31063
The vial of cleaning compound contains alumina (CAS Number 1344-28-1) as a very fine powder. Cleaning
should be undertaken in a well-ventilated area. A full material safety data sheet MSDS is available on
request from Ion Science Ltd. Key safety issues are identified below:
Cleaning the Lamp
Use of MiniPID lamp cleaning kit A-31063
1. Open the container of alumina polishing compound.
2. With a clean cotton bud, collect a small amount of the
powder.
3. Use this cotton bud to polish the PID lamp window. Use a
circular action, applying light pressure to clean the lamp
window. Do not touch the lamp window with fingers.
4. Continue polishing until an audible “squeaking” is made by
the cotton bud moving over the window surface. (usually
within 15 seconds)
5. Remove the residual powder from the lamp window with a clean cotton bud. Care must be taken not to
touch the tips of cotton buds that are to be used to clean the lamps as this may contaminate them with
finger print oil.
6. Ensure the lamp is completely dry and any visible signs of contamination are removed before refitting.
Discarding the MiniPID pellet
Discard the contaminated pellet. The pellet does not have any toxic components, but if it has been
contaminated by toxic materials, then show due care when disposing.
