Certification
Wheal Jane Laboratory is certified to ISO 9001 and ISO 14001. Precision is controlled by the use of appropriate reference materials, quality control samples and blanks, and by varying the numbers of duplicates analysed as appropriate in each batch. Small batches of individual samples are carried out in duplicate by different technicians or analysts as required. In addition, the laboratory operates an internal and external checking system for all routine analysis methods, including regular international round robin proficiency testing.
