The Research Analytical Laboratory uses a number of techniques to provide the customer with superior Quality Control/Quality Assurance, including:
- careful sample preparation
- state-of-the-science instruments and techniques
- reporting of sample duplicate results
- analysis of multiple blank solutions
- use of in-house checks and certified reference materials with each analytical run
- routine and frequent instrument calibration and verification
- sample spiking for new matrices
We also participate in a number of round-robin laboratory proficiency programs for water, soil and plant materials.
