As an example1, to demonstrate the possible impact of some of these different preparations, we can compare the arsenic concentration in a soil, utilising three pre-treatment methods: 1. Sieving and analysing the < 2 mm fraction 66.6 mg/kg 2. Sieving and analysing the < 10 mm fraction 30.6 mg/kg 3. Analysing the whole sample 20.0 mg/kg.

Read MoreSoil Sample Preparation 1 DATE: May 2005 Soil Sample Preparation 1. Application Soil samples are dried, ground and sieved prior to analysis. The grinding and sieving operations should ensure a homogeneous mixture for analysis. 2. Summary of Methods Soil samples are dried at 50°C in cardboard boxes. The dried soil is ground in a mechanical
Read Moresample preparation form. Drying the samples is critical because even slightly damp soil will clog the screen openings rather than flowing through them. 8. Transfer the dried sample into the 10-mesh sieve of a sieve stack, then weigh the aluminum foil by itself and record the weight of the aluminum foil in the appropriate column of the sample ...
