Our chemical analysis facility provides a comprehensive range of standard and specialist composition tests for inorganic analysis. Our expert staff handle samples from plants, trees, soil and water following strict quality assurance protocols.
Quality assurance
Our chemical analysis facility is among the top performers in Europe for plant, water and soil analysis. We have ranked No.1 in the most recent EU-wide Interlaboratory comparisons:
3rd in 2018 out of 30 European laboratories for soil analysis (European Soil Survey –ICP Forests)
1st out of 59 European laboratories for plant analysis (ICP Forests)
3rd in 2019 out of 40 European laboratories for water analysis (ICP Forests)
The laboratory operates under the Joint Code of Practice for Research as our benchmark on quality assurance. We are also a member of a number of proficiency schemes to ensure our work remains of a high standard. These include:
Yearly water proficiency test under the European Monitoring on Environmental Pollution project (EMEP) (No ranking available)
Water (every other year) and plant (yearly) proficiency tests under the EU programme (ICP Forests)
Every 3 years soil proficiency tests under the European Soil Survey programme (ICP Forests).
We also use:
Certified Reference Materials (plant, soil or water) are run in every batch of analysis with matrix matching to maintain the quality of our data which is paramount in research and long term monitoring.
Reference standards used through out every batch of analysis to assess any significant drift or change in sensitivity.
Experienced staff some educated to BSc, MSc and PhD level.
Expertise
We have supported forestry-related research projects for more than 50 years. Through this active participation in research we have acquired significant expertise in testing a wide range of materials and developing protocols.
Our clients include research organisations and university research groups from across Europe as well as environmental consultants, forestry contractors and private woodland owners.
The Chemical Analysis Laboratory provides a wide range of inorganic analyses for plant, soil and water samples; including composts, effluents, sludges and even animal tissues (e.g. invertebrates).
We have a modern, well equipped laboratory with analytical instruments such as:
2 Elemental Analysers (Carbon and Nitrogen in water and soil/plant)
GC (Gas Chromatography) for gas analysis
Automated pH and Alkalinity meter.
We also have specialised equipment for sample homogenisation and preparation such as:
Jaw crusher, grinder and ball mill
High accuracy 6 digit weighing balance
Sample heating blocks
Microwave digestion system
Centrifuge.
Our new dual view (axial and radial) ICP-OES (optical Emission Spectrophotometer) allow much lower limits of detection than conventional ICP-OES and gives us great accuracy at trace levels.
Elemental analyser recently purchased for the European Soil Survey (BioSoil) project for measuring nitrogen and carbon (both organic and inorganic forms) in soils. This instrument can also be used for analysing other solid media such as plant samples.
High Performance Liquid Chromatography for analysing anions in water or other aqueous extracts (plant and soil).
The Chemical Analysis Laboratory is based at Alice Holt Lodge in Farnham, Surrey.
