For MET ONE and HIAC particle counting equipment, the CoreCAL calibration system is required to make adjustments that may be needed to maintain resolution and counting accuracy to industry standards. Performing an instrument verification following calibration adjustment will confirm if your instrument is performing within manufacturer’s tolerance CoreCAL also gives an “As Received” data as part of a full calibration), to inform you as to what extent the instrument has drifted since its last calibration Audit quality CoreCAL calibrations are available through a Beckman Coulter Service Network.
