Hello. I'm using a Shimadzu GC 14A with FID and an RTX 5 capillary column.
I have optimized all my parameters and have checked with Shimadzu and they
concur. They sent me very arcane instructions on cleaning the detector. I
am planning to replace the nozzle, but would like to avoid cleaning the
detector if possible: it seems very detailed and laborious. 
Has anyone cleaned an FID detector like this? If so would you mail or post
about your experience?
thanks!
Adam

I m an student in Spectrochemistry and my subject's trainee is the study
of an Essential Oil of Patchouly by Mass Spectrometry coupled with gas
chromatography.  So, I search for mass spectra of the Patchouly oil like
... 
   -  Patchoulenone            M=218   C15 H22 O
   -  Isopatchoulenone         M=218   C15 H22 O
   -  Norpatchoulenol          M=206   C14 H2  O
   -  Pogostol                 M=222   C15 H26 O
   -  1 alpha - 5 alpha Epoxy - alpha Guaiene    M=220 C15 H24 O
   -  1 beta - 5 beta Epoxy - alpha Guaiene      M=220 C15 H24 O
   -  1,10 Epoxy alpha Bulnesene                M=220 C15 H24 O
   -  alpha Patchoulone        M=220 C15 H24 O
   -  beta Patchoulone         M=220 C15 H24 O
   -  5 oxo Patchoulol         M=236 C15 H24 O2
   -  alpha Guaienone          M=218 C15 H22 O
   -  alpha Cedrenal           M=218 C15 H22 O
   -  beta Patchoulenone       M=218 C15 H22 O
   -  gamma Selinene           ?
   -  Pogostone          M=224 C12 H16 O4
   -  alpha Elemene      M=204 C15 H24
   -  Beta Bulnesene     M=204 C15 H24
  Thank you for your help.

i don't know 
i need a little advice on sample prep. (pH...etc.)
and the proper column and column temp.
does this help?

Do there exist alternate suppliers of ball bearing grease for Alcatel 
turbomolecular pumps?  We are finding out how costy the syringe 
refills are...
