One of the key factors affecting laboratories’ capabilities to produce reliable test data is the availability of standard materials with property values that can be relied upon by their users. The quality of a result is dependent on the quality of standards used to validate a method, or calibrate an analytical instrument. Every day, standards are used to calibrate instruments, or validate test methods, e.g. pH meters, Conductivity Systems, Auto-titrators or Karl Fisher Titrators, If the standard is not accurate, this inaccuracy will be reflected in the test result.
