Quality Control sample analysis
Three levels of quality control samples are analyzed over the 24 hour period of instrument use. The normal control is usually analyzed during the first 8 hours of use. The samples are sealed in glass vials, maintained at a constant temperature, mixed thoroughly prior to use and opened carefully using a safety device. Since only one control is analyzed and evaluated at a time 95% confidence limits must be used.
