5. Using the appropriate combustor extractor tool (Part #280719 for 2-mm I.D.
combustor; Part #280727 for 3-mm I.D. combustor) (see Figure 4.9) and
Teflon-coated forceps, carefully remove the combustor from the detector
body. Invert the combustor extractor tool, immediately reinsert it into its
protective sheath, and stand it on end. Make sure that it is placed where it will
not be accidentally knocked over.
6. After the combustor has been placed within the protective sheath, carefully
examine the combustor for signs of contamination. If the combustor does not
appear to be contaminated, place it in the plastic receptacle in which it was
supplied or in a clean, sealable plastic bag, and store it in a safe place. If only
changing the combustor, go to “Installing the Combustor” in this chapter.
Examining the Column Tip
1. Verify that the combustor has been removed.
2. Remove the detector body mounting screws (Part #295295C) using a U/yr"
Allen wrench. Place the screws on a clean lab tissue.
3. Gently lift the detector body straight up and off of the detector base, taking
care not to crush the column extending beyond the top of the combustor
support. Place the detector body on its side on a clean lab tissue.
