Attentive to the needs of the laboratory public, Controllab provides Certified Reference Materials (CRM), an important tool in the quality control of analytical routines.
Controllab has been accredited since 2016 as a Certified Reference Material Producer by the General Accreditation Coordination (Cgcre/Inmetro), under number PMR 0009, according to the scope published at www.inmetro.gov.br.
The use of CRM adds precision, accuracy and traceability to an analytical process, enabling more reliable measurements.
Here are some purposes and benefits of the CRMs:
Performance Verification
Measurement Quality Control
Validation of Analytical Methods
Equipment Calibration and Verifications
Metrological Traceability
The following tables list the quantities and respective property values available:
