Rothamsted Research

where knowledge grows

The Analytical Unit is based within the Sustainable Soil and Grassland Systems Department (SSGS), and provides extraction, digestion and analysis procedures as a service in support of the research programmes of the Institute.

We use some of the most advanced instrumentation available, providing high level performance in terms of speed, accuracy, precision and reliability. Our service encompasses initial discussions with research staff at the project proposal stage, quotes for costing purposes, sample registration (the Analytical Batch System), preparation, processing and measurement.

We also undertake some external work for other Research Institutes and Universities. If you would like to know more about the services available please contact Adrian Crosland (email) or Wendy Wilmer (email)  for more information.

Quality Assurance

Quality Assurance is an essential part of sound laboratory practise, to achieve optimal performance the Unit follows the Joint Code of Practice (JCoPR) and participates in European Quality Assurance programmes. The International Soil Exchange (ISE) and International Plant Exchange (IPE) programmes both based in Wageningen in the Netherlands send test samples 4 times a year.

Performance is strictly monitored using certified external standards alongside our own in-house standard materials. Standards and check samples are monitored and recorded using Shewhart Control Graphs and computer based quality control packages.

External quality control programmes and sample exchanges are frequently carried out with collaborators and we have close links with the Analytical laboratory at North Wyke.

Analytical Staff

Analytical Unit Facilities

Solid samples submitted for analysis are prepared by drying, grinding and fine milling in the Jenkinson Building Sample preparation facility here at Rothamsted. Within the Analytical Chemistry Unit samples are tracked through the system using a computer controlled booking in system for traceability and archiving purposes.

Analytical Instrumentation

The Analytical Chemistry Unit has a suite of air conditioned instrument laboratories equipped with the most advanced instrumentation available, providing high level performance in terms of speed, accuracy, precision and reliability.
