Soil Sampler for Solution Sampling

Q1: What is a soil sampler for solution sampling used for?
A1: It is designed to collect soil pore water (soil solution) for chemical analysis, such as testing for nutrients (e.g., nitrates, phosphates), pH, salinity, or contaminants. The sampler can be left in place for long-term monitoring or removed and relocated. Repeated use requires proper cleaning to avoid cross-contamination.

Q2: What is the ideal depth range for sampling?
A2: Most models allow sampling from 15 cm to 90 cm depth, depending on probe length and soil conditions. Deep samplers can access root zone solutions effectively. Sampling frequency depends on the application. For nutrient monitoring, weekly or bi-weekly sampling may be appropriate. Environmental studies may follow different intervals.

Q3: How does this type of soil sampler for solution sampling work?
A3: The sampler is inserted into the soil at the desired depth. A vacuum is applied to draw soil solution through a porous ceramic tip or membrane into a collection chamber or tube. Collected samples are not sterile. If sterile or particle-free samples are required, additional filtration or sterilization steps must be performed after collection.

Tips: Instructions for using the soil sampler for solution sampling:

1. The suction-type soil solution sampler can be buried at any location, with a maximum depth of up to 15 meters.
2. Choose appropriate sampler lengths as needed and possible, typically 15 cm, 30 cm, 45 cm, 60 cm, 90 cm, and 120 cm.
3. The ceramic head has a diameter of 31 millimeters and a length of about 7 cm. Drill a hole with a diameter of 32 mm and a suitable depth at the location where the soil solution needs to be extracted, and insert the sampler vertically into the hole, paying attention to leaving a surface height.
4. Use a water stop (gas) ring to clamp the water outlet rubber pipe and seal it.
5. When extracting the solution, insert the manual air pump interface into the air pressure pipe port and release the water stop ring of the water outlet pipe. Inject positive air pressure into the air pressure pipe and place a pre-prepared container below the water outlet rubber pipe. When the air pressure reaches a certain level, the solution will automatically flow out.
