What do I measure?

Different analysis can be conducted on the collected soil solution : ionic content, pesticides, etc.

Groundwater pollution is now a well known problem around the world. The danger occurs when polluting molecules leach through the soil and into a water sheet supplying a drinkable water tank.

The SPS 200 soil solution sampling system is a simple equipment built to help environmental scientists study the movements of molecules in the soil. It can extract water coming out of cultivated soils or any other type of soil.

The principle on which the SPS 200 works happens to be cheap, quick and most of all efficient. The soil water is drawn into the porous ceramic cup.

It will only take two days to collect enough solution in order to have it analysed (nitrate, pesticide or other molecule's concentrations, measuring out fertilizers ...).

Key Advantages


Not chemically inert with all elements or molecules


This system collects the soil water which is freely moving in the soil. The system works as long as the soil water potential is in the 0 / -850 mbar range.

Working principle :
A porous ceramic cup is fixed on the bottom of an empty PVC tube.
The tube is introduced into the soil in order to collect the soil solution.
After creating a depression inside the tube (with vacuum pump ref. SPS 400), the soil solution is drawn out of the soil trough the porous ceramic cup and into the tube.
After a few days, a vacuum pump (ref. SPS 400 or PAV 2000 ) and collection flask are used to collect the soil solution contained in the SPS tube.
The soil solution is then transfered into a sampling flask which is brought into the laboratory to have its content analysed.
The solution can also be analysed in the field with a field analyser, reflectometer (ref. 169700001).
The porous ceramic cup used for the SPS 200 system exists in two different diameters (31mm and 63mm).
This enables you to work eventually with different volumes of collected solutions.
The 63mm ceramic cup (SPS 200-63) will collect twice as much soil solution as the 31 mm ceramic cup (SPS 200-31).

The standard set

Each SPS lysimeter is delivered complete with a top stopper, porous ceramic glued on the tube and stainless steel clamp.

You also need

. An auger to install the lysimeters into the soil.
. A vacuum pump to prepare the lysimeters and collect the soil solution, either manual, ref. SPS 400or electric, ref. PAV 2000
. A collection bottle, ref. SPS 300 (complete with 2m of Ø4mm PA tubing).

Can the collected solution be used for trace metals measurements ?

For trace metals analysis in soil solution, we recommend the use of a more inert material than a porous ceramic or stainless steel cell to collect the solution, such as the PTFE lysimeters or the RHIZON M.O.M micro sampler if you need to sample in soil columns.

Can the collected solution be used for pesticide measurements ?

The porous ceramic on this type of equipment is suitable for pesticides analysis.
