Removal of interferences in ICP/MS using

deuterium as a collision gas

he use of collision cell in ICP/MS has brought the

removal of isobaric interferences in Ar ACP/MS

especially for the species related to Ar background

such as Ar dimers and Ar related molecular species.

Determination of Fe or Se has been limited because of

those interferences. However, the use of collision cell can

eliminate or reduce molecular interferences. Hydrogen

or Helium has been used as a collision gas. Different

approaches such as reaction cell could be introduced

instead of collision by using more reactive gases such

as ammonia. However, the introduction of hydrogen in

the collision cell does react with sample elements and

produce molecular species to some degree. Matrix such

as Br could react with hydrogen to make BrH to interfere

on the determination of Se. The use of deuterium can

alleviate this problem. The accuracy and precision could

be improved by the use of deuterium especially for the

complex matrix samples. Details of the improvement

of complex matrixed sample such as oyster will be

discussed.
