Regarding the Al ISO-100 knife edge seal for the Delta Plus XP, I was able to locate a vendor in CA in addition to the vendor Bruce listed below: Norcal www.n-c.com 1-800-824-4166 P/N: ISO-100-MS-A Price: $40.23 (as compared to the $87 that thermo charges) Still looking for a source for the MAT253 ion source lamp wire, in case someone had some luck locate a "cheaper" source.
