Dear Isogeochemists,

We might need to change a filament and/or clean the source of MAT 253. I 
am preparing a list of materials that we may need.  I found most 
quartz/ceramic rods came with the mass-spec.  There are couple of 
ceramic rods (0439530) and a gold gasket (055-1600) that I would like to 
have before opening up the source. 

I am wondering if anybody used any providers (SIS?) that supply those 
materials, and how it worked out (same as thermo products?).  The gold 
gasket is 115 mm OD/113mm ID and 1mm thick or so but these measurements 
are not very accurate (what I have is an used one); if anybody has 
accurate measures handy, I would appreciate it as well.

Thank you very much,

Shuhei
