The chemicals used when following this procedure are harmful, therefore the correct
safety precautions must be carried out. During handling, avoid inhalation and contact
with the eyes or skin.Wash hands thoroughly after use.Refer to the data sheets for
further details of the chemicals used.
The process of using this chemical substance is harmful, therefore correct safety and preventive measures must be taken. Avoid inhaling particles during use, avoid contact with skin and eyes, and wash hands carefully after use.
1.2 Method of Preparation 101940 Calibration Reagent
The Fuller's Earth is supplied in a sealed 20g package, the package contains sufficient
to make a ) solution when combined with 1 litre of water. Alternate solutions can be obtained by increasing the amount of water used as shown in the table below.
Sealing 20 grams of calibration substance in a plastic bag and adding one liter of pure water can prepare a calibration solution of 20000 mg/l (20 g/l). Preparing calibration solutions of other ratios can be achieved by increasing the capacity of pure water.

The following points should be observed when preparing and using Fullers Earth
solutions:
• The water used should be freshly distilled or de-mineralised
• Ensure the container used for the solution is clean
• During preparation and use, keep the solution covered to prevent contamination
• When using the solution it must be continually stirred to ensure accurate and
consistent measurements and to prevent settling
When preparing calibration solutions, the following points should be noted:
Pure water is freshly distilled mineral free water
Ensure that the vessels used for the solution are clean
During the preparation of the solution, it is necessary to cover the container to prevent contamination
Continuous stirring is required during use to prevent sedimentation and ensure the accuracy and consistency of the calibration solution.
