Shuhei:
Part# 055-1600 is the gold gasket you need. 
I never used SIS gold wires for this particular gasket before, but we
did for other places before. They work fine. We also often use the same
flattened gasket twice. In that sense, there should be a little room for
slight differences in diameter or width of your gold wire.
Good luck.

Subject: [ISOGEOCHEM] Gold gasket/ceramic rods for 253

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
