Considerations of bias and precision associated with ISE based measurements of sediment ‘free’ sulfide / F.H. Page and D.K.H. Wong.Fs70-5/2025-017E-PDF

"This document utilizes literature and new data to examine the bias (systematic error), precision (non-systematic or random error; indicated by standard deviations and coefficients of variation (CV)) and total uncertainty or accuracy (includes bias and precision) associated with aspects of Ion Selective Electrode (ISE) measurements as applied to the determination of “free” sulfide in marine surficial sediment associated with aquaculture operations. The examination concludes that a careful and experienced analyst should be able to routinely achieve ISE sulfide measurements that have a total uncertainty of 10% or less when standard solutions, electrodes and samples are not stored, standard solutions are titrated and millivolt readings are made within 2 minutes of electrode insertion into a sample and electrodes are regularly checked and calibrated (at least once every 3 h)"--Abstract, page v.
