Garantía de calidad

Addista

Prerequisite for precise and accurate results is a permanent quality assurance. Only analytical quality assurance turns your measured values into reliable analysis results. addista is the system with which you can check the precision and accuracy at any time. Regular checks safe guard the long-term reliabilty of your measuring system, of your handling and the materials you use (pipette, reagent, photometer, etc.).

Standard solutions
Standard solutions are used to the equipment (photometer, pipettes, cuvette tests, etc.) and the user’s working procedures.

Spiking solutions
Spiking solutions give assurance as whether the sample contains spurious ingredients that could falsify the result.

Ring test solutions
Ring test solutions of unknown concentration are analysed by the user and the result is sent in. Working procedures and materials are tested in the ring test. Participation is confirmed by means of an inter-laboratory test certificate.

A participation of the user in round-robin tests is often a prerequisite for the acceptance of equivalence of operational analysis methods. Upon successful participation in the HACH round robin test, the student will receive a full test evaluation plus certificate.

Analysis and quality assurance measures are inseparably interlinked. There is much more to ensuring high quality measurement results than simply the type of analytical method (standard/norm vs. operational analysis) that is used. The care taken over the individual work steps and the quality assurance measures that are implemented, play a much greater role. Hach® supports users of LCK Cuvette Tests by carrying out a substantial part of the quality assurance measures on their behalf. This means that the relevant quality and batch certificates are always available.
