Thermo/Finnigan MAT Copper and Silver Lead Wire



Both copper and silver wire are available for use on Finnigan mass spec sources. Finnigan has routinely used 0.020" diameter copper in the past for this purpose. Silver however, is a better conductor and is used by most other instrument manufacturers. In addition, silver is not as reactive with gases, such as ammonia, when used in CI operations. The silver wire being offered is pure silver and the copper is bare, uncoated OFHC hard copper.
