Instrument calibration ensures quality in processes


When calibrating, the user reduces costs, fulfills certification and accreditation requirements and ensures quality in the analytical process

Instrument Calibration is a process that certifies that the measurement obtained by an instrument is compatible with what is expected and that it is suitable for use, in order to avoid deviations in the analysis processes and reduce costs.

In general, it consists of comparing the results obtained by the instruments with those obtained by standards (traceable to national/international reference standards), under pre-established and controlled conditions.

In a laboratory, all measuring instruments that have an influence on the accuracy or validity of tests need to be calibrated. In general, also in industries and other segments, calibration must be used in order to avoid changing properties with impacts on products or services.

By performing the Calibration, the user certifies that the instruments used in the analytical process are compatible with the expected performance. Its main benefits are:

  • Ensure quality in analytical processes;
  • Reduce analytical costs and increase productivity;
  • Comply with certification and accreditation requirements;
  • Maintain proper functioning of instruments;
  • Increase the useful life of equipment.

Calibrating avoids waste and rework, as well as preventing accidents. Remember that the instrument must be calibrated after purchase, or before starting use, before and after maintenance. And of course, at stipulated intervals.

Understand calibration in practice

In summary, the purpose of calibration is to verify if the measurement obtained by an equipment is compatible with what is expected and if it is suitable for the activity for which it is intended.

For example: a 10 uL micropipette is used during an assay where the maximum error allowed by the customer is +/- 0.5 uL (tolerance of 9.5 uL to 10.5 uL) and the calibration result shows an average result of 10.6 uL. This instrument should be considered unsuitable for this use and intended for an activity with greater tolerance, if maintenance for adjustments is not performed.

Certification and accreditation in the laboratory segment

The quality in the processes is no longer just an addition, becoming a mandatory item. Some criteria and standards are essential for the proper functioning of the laboratory. Criteria stipulated by CLSI/NCCLS, American Society for Microbiology, ABNT NBR ISO 9001, 15189 and 17034 standards and ABNT NBR ISO/IEC 17025 and 17043 standards, require the calibration of glassware, micropipettes, scales, thermometers, among others.

By contribution to the reliability of results and reduces the costs inherent to testing errors, calibration is now a requirement for certification and accreditation processes.

Ensuring the reliability and credibility of the results is being ahead, it is becoming a natural option. Quality is a determining market differential, especially when these results interfere with health and the environment, which is the case with clinical trials, on food and water, among others.

Why calibrate with Controllab?

Controllab has been accredited by the General Coordination of Accreditation (Cgcre) of Inmetro, under CAL nº 0214, since 2002.

In addition to all the accumulated competence, the delivery time is minimal, ensuring the necessary agility for the instruments to return to the users’ routine without major interruptions, with an excellent cost/benefit ratio.

An extensive scope of instruments is contemplated in the Controllab Calibration Laboratory:

  • Scale
  • Volumetric flask
  • Thermostatic bath

PRM 0009

Accreditation Cgcre/Inmetro - Certified Reference Material Producer

Controllab has been accredited as a Certified Reference Material Producer (MRC) since 2016 by Inmetro’s General Coordination for Accreditation (CGCRE), under the PMR 0009 number. The assessment of this conformity is carried out according to the requirements established in ABNT NBR standards ISO 17034 and Inmetro, thus ensuring competence for the production of MRCs, according to the Scope of Accreditation.
Cgcre is signatory to the Mutual Recognition Arrangements of the International Laboratory Accreditation Cooperation (ILAC) and Interamerican Accreditation Cooperation (IAAC).

CAL 0214

Accreditation Cgcre/Inmetro - Calibration Laboratory

In December 2002, the Calibration Laboratory was accredited by Inmetro’s General Coordination for Accreditation (CGCRE). With this recognition, it became an integral part of the Brazilian network of accredited laboratories, under nº214. Since then, it is periodically evaluated for the maintenance and/or extension of accreditation.

PEP 0003

Accreditation Cgcre/Inmetro - Proficiency Test Provider

In September 2011, Controllab was accredited by Inmetro’s General Coordination for Accreditation (CGCRE) as a proficiency test provider, under nº PEP0003. Initially as part of a pilot project by Inmetro, this accreditation was based on ILAC G13: 2007 and included several clinical and hemotherapy tests. In the periodic evaluations of this accreditation, new segments and tests are included and the evaluation is now conducted according to ABNT NBR ISO/IEC 17043.

This accreditation attests to Controllab’s technical competence to develop and conduct proficiency tests in accordance with international requirements and enables it to be recognized in other countries, in accordance with mutual recognition agreements signed by Brazil in Mercosur, the Americas and Europe.
