Sulfite Control

Sulfite (I and II) Control is a synthetic liquid material that contains stabilized sulfite at adequate concentrations for quality control in laboratories. It does not contain preservatives that could interfere with the measurements.

The concentration values assigned to each level are shown in the attached tables. The values are traceable to the unit of mass. Traceability is ensured only by using the measurement reagents and procedures recommended by BioSystems. The acceptable ranges suggested have been prepared based on prior experience in interlaboratory variability and are provided only as a guideline, as each laboratory should establish its own precision parameters.
