Описание: The precious metal catalyst (PMC) market world wide is approximately 15.8 billion per annum and estimated to increase to 22.3 billion by 2027, with a GACR of 5.1%. Profitability of reclaiming these precious metals is very dependent on the accuracy of the determination. 0.5% accuracy or tighter is a typical requirement.. Achieving this on an ICP is not trivial with typical uncertainties of 1% for the technique. The following work will highlight Pt, Pd, and Au stability and accuracy. Also, HCL and Nitic Acid need to be kept consistent and is typically not quantified using ICP. However, data is presented by analyzing both chlorine and nitrogen to ensure consistent digestions.
The newly designed Agilent 5800 ICP was used for this project. Focus and resolution have improved dramatically leading to less interferences and tighter % R.S.D. per measurement due to increased sensitivity. Deconvolution techniques have improved signal to noise ratios and eliminated interferences. Using confidential drift correction techniques and up to 16 wavelengths per analyte will show accuracy improvements to less than 0.5 % and precision improvements to less than 0.3 %.
