Entry from British & World English dictionary
noun[mass noun] Electronics & Physics

- If a maximum permissible residual gas pressure is exceeded, the electron source is automatically shut down and a gettering process is activated.
- When the gettering medium becomes oxidized, it no longer removes the oxygen from the gas stream.
- Much has been written about gettering in the last 25 years or so, but in essence it all boils down to this.
