4. SOIL EXTRACTION KIT
4.1 GETTING TO KNOW YOUR SOILS KIT
The Soil extraction kit contains all the equipment and accessories required to carry out
a digestion/extraction procedure for 5 metals, Cd, Pb, Cu, As(Total) and Hg. These
require three digestants, labelled as D1, D2 and D3.
The digestants are supplied in recyclable 4ml bottles and contain the correct amount
so no measurement is required.
Each set of digestant is sufficient to provide enough extract to perform at least 3 tests.
One extract can be used for the analysis of Cd, Pb, Cu, As & Hg.
To carry out an extraction procedure you will require the mixer. The mixer is very
similar to the sonde and is connected to the hand held instrument in the same way as
follows:
The Mixer Assembly
The Mixer SAB (Sample Analysis Beaker)
In-line waterproof cable connector
Also contained within the box is a portable balance which is used to weigh the soil
samples. The balance can be used at angles up to 15º allowing it to be used in the Peli
case on uneven ground but the box should be stable and the balance zeroed once in
position and kept in that position during use.
