101940 Calibration Reagent

Seal 20 grams of calibration substance with 101940 calibration reagent in a plastic bag, and add one liter of pure water to 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. 101940 Calibration Reagent

1.1 Health & Safety PrecautionsHealth and Safety Measures 101940 Calibration Reagent

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.
