CLAY FRACTION

ISO 11277 - Clay fraction - pH - Soil

 

Brand:
Product: CLAY FRACTION

Description:

The capacity of soil to transport pollution can be influenced by a number of factors such as absorption, the ability to shrink or swell, water retention and permeability.
Most of these factors are independently correlated with the particle size of the soil.
The clay fraction, the smallest fraction (0-2 micron), is indispensable in assessing soil quality.

Skalar has automated the determination of clay fraction according to ISO 11277.

This test involves very precise timing stages, tasks much more easily performed by the robotic analyzer rather than human operators.
The analyzer provides automatic addition of sodiumpyrophosphate solution and distilled water, sample homogenizing, automatic sample pipetting, evaporation and drying of sample trays and calculation of the clay fraction.
The SP2000 has from 35 up to 105 positions for 1000 ml sedimentation cylinders and from 35 up to 105 positions for evaporation dishes or vials.
The analyzer can also provide automation of other fractions in soil.

Skalar's SP2000 platform can be configured for measurement of soil-pH in water extracts as well as in KCl, CaCl2 or other extracts.
The procedure includes automatic probe calibration, addition of extraction solution, automatic stirring, pre-defined sample settling times and measurement.
The analyzer can have a capacity of up to 792 containers of 50 ml.
For extremely large batches the analyzer can be configured with two robotic arms each with multiple electrode onfigurations, up to a total of 8 electrodes.
