An experienced SGS inspector will periodically perform on-site inspections of the analyzer and associated coal sampling system on a fixed schedule to collect reference block data and collect special samples used for on-going performance monitoring of the system. Shortly after the visit SGS provides a report detailing the calibration results, any deficiencies noted and drawing on our experience, offers recommendations for enhancements and improvements to the system and procedures. SGS also does continuous surveillance by monitoring differences between shift, daily or shipment samples against analyzer results, using optimum statistical routines for detection of analyzer drift. |
