Hi. I would like to ask regarding the interference that commonly happen in Arsenic measurement. So I wanted to analyze the arsenic content in a sodium chloride sample, however as we know, there is an ArCl interference thay could lower the accuracy of the arsenic measurement. I've read several journals that used He collision reaction to combust this interference, however when I tried to applicate this method, it still gives a bad accuracy. I was wondering if there is another option to reduce this interference, beside the usage of He and coupling LC to the ICP-MS. May a precipitation method help in achieving this interference, maybe the usage of Ag, as it can help in precipitating the Cl? Thank you
