Quadruple Mass Spectrometer (QMS)

We recommend QMS especially in conjunction with our Fluidized Bed Reactor (FBR) option. It allows analysis of composition of gases exiting the reactor. With this information, the correct length of the ALD pulses can be accurately determined. 

In developing new ALD processes, QMS is very helpful and can speed up the development work tremendously. Again, by analysing the composition of gases exiting the reactor, we can determine if the desired reactions have taken place in the reactor, and we can adjust the process parameters accordingly.

QMS can also be used as a residual gas analyser to make sure that the ALD system is leak-tight, removing the need for an additional He-leak tester.
