All analytical measurements, including conductivity measurements, must be of suitable accuracy and must be proven correct if they are to be fit for purpose. This paper, The Application of Good Laboratory Practice in the Selection and Use of Accurate, Traceable Conductivity Standards, describes how these requirements are achieved through the application of good laboratory practice in the selection and use of calibration and control standards. For high quality analytical measurements, establishing measurement traceability and quantifying the Uncertainty of Measurement are essential. This paper describes how these factors can be established and the critical role that standards play in determining these factors and thus ensuring the quality of conductivity test measurements. As well as giving specific information on conductivity standards, this paper gives details relevant to the selection and use of all analytical standards.
Reagecon produces a wide variety of conductivity standards ranging from 1.3μS/cm to as high as 500,000μS/cm and have vast knowledge on this subject. There are several other papers available on conductivity such as Equipment – A Guide to Choosing a pH or Conductivity Meter and The Selection and Use of Instruments for Accurate Conductivity Measurement.
