The Chemical Testing Laboratories receives pulverized geochemical samples from the physical testing laboratory and carry out chemical analysis as per customer request. The laboratory does a wide range of analysis in geochemical samples such as major, minor, trace and ultra-trace elements and many others.ย This laboratory also conducts borehole water analysis to determine its quality. The laboratory gives technical advice on water quality test reports basing on BOS 32:2009 for human drinking water specification and BOS 365:2010 drinking water for livestock and poultry specification.
The laboratory is implementing ISO/IEC 17025 standard, which is a general requirement for the competence of testing and calibration laboratories in order to accredit its test methods and earn international recognition.
The laboratories have implemented Laboratory Information Management System (LIMS) to monitor its technical and management processes.ย The system is the key driver in enforcing the laboratoryโs Quality Control (QC) and Quality Assurance (QA) procedures, the functionality needed to satisfy accreditation requirements as per ISO 17025.
To ensuring the validity and reliability of results, the laboratories participate in the Proficiency Testing schemes such as, South African Bureau of Standards Water Proficiency Testing Scheme (Regional), SADCMET Water Proficiency Testing Scheme (Regional) and International Geochemistry Proficiencyย Testing Scheme -U.K (international). These schemes monitor, assure quality of the results as well as checking competence of personnel.
