Verifying the accuracy of Brix measurement with a refractometer is done with Brix standards, which are produced onsite by mixing sugar and water in a defined proportion. Occasionally, traceable Brix standards are purchased from a certified company in order to test the instrument with an external certified standard. These standards are expensive and have a limited shelf life, this is why for the "daily" routine, standards are used which are produced in-house. Being able to make the standard onsite in a traceable and guided method is a great benefit for such operations.
This white paper describes a guided workflow, using a balance and a refractometer connected to the LabX PC software to produce Brix standards onsite, increasing the accuracy and traceability and eliminating transcription errors.
