I have two gas source mass specs that are availalbe.
One is an ancient Nuclide 6"-60deg. It has two extraction lines. One
is designed for RF induction heating and the other for a furnace.
The other is an MAP215-50 with an CO2 and Nd/YAG laser extraction line
with x-y-z stage and video camera. It also has furnace extraction
line as well.
