Hydrogen Selenide can be diluted with argon, helium,
hydrogen or nitrogen in order to provide concentrations of less than
100%. Using Hydrogen Selenide in this form can add an additional degree
of control to the process, particularly when relatively small amounts
of selenium are to be deposited. Mixtures are analyzed prior to shipment
to ensure that the concentration is in the range requested. Hydrogen
Selenide mixtures are prepared as ordered. Concentrations other than
those listed below are available upon request.
