The present invention pertains to the construction of analytic instruments and can be used for analysing natural and industrial water biological samples, geological samples and air. The purpose of this invention is to reduce substantially the power used by the atomiser and the analyser and to increase , the number of objects that can be analysed. To this end the method for the , thermionic atomisation of a sample involves carrying out an ionic sputtering of the sample from the cathode in a low-pressure discharge. The cathode is heated by the discharge to a temperature of between 800 and 1400 ~C while the , ballast gas consists of Kr or Xe under a gas pressure of 10 to 15 torrs. The …

Why it's free to use
- Filed September 21, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 21, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 21, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
