2.NOTE 1For safety reasons it is recommended to acidify the test portion under a hood as volatile toxic substances can begenerated.NOTE 2In cases where high contents of soluble solids are leached, acidification of the eluates can lead to precipitation of salts.This can be avoided by dilution prior to acidification.5 Blank determinationThe blank contribution of the analysing procedures shall be determined as described in the analytical standardsand considered in the calculation of the results when appropriate.6 InterferenceSeveral types of interference effects can contribute to inaccuracies in the determination of the various parameters,especially at low concentrations. These potential interference effects are listed in the individual standards and shallbe considered separately for each analytical technique.Chemical interference is characterized by molecular compound formation, ionization effects, solute vaporization,precipitation and effects of decomposition of organic matter. Addition of buffer and/or preservation methods mayreduce these effects.Physical interference can be caused by changes of viscosity and surface tension. They can cause significantinaccuracies especially in eluate samples containing high concentrations of acids and/or dissolved components.The colour or turbidity of eluates can cause interference in spectrometric determination.Standard addition may be used to visualise and correct for interference effects (see ISO 8466-3).SIST EN 12506:2004
