Measuring iodine in 1% TMAH on ICP-MS 8900. We have the Sapphire PFA Inert Kit (not sure if 2.5 or 1.5 mm), platinum cones and brass base plate. Will our kit work with 1% TMAH or be degraded? I've noticed other kits for organic solvents have used quartz or platinum. Colleagues have said to run on no-gas mode but Shikamori et al. on 8800 used O2 cell gas on MS/MS mode to eliminate Xe contamination signal, any guidance?
