All analytical data collected from automated instruments is sent to LIMS electronically, not entered by hand. This avoids the inevitable transcription errors that can result from hand entering large amounts of data. This includes all organics, metals and even certain general chemistry tests. The only data entered by hand are tests that are completely manual and do not lend themselves to this type of automation. 2. Data processing/data approval

All data (regardless of how they enter the system) follow a tightly controlled “assembly line” of calculations, automated checks and approval steps. Both analyst and supervisor must review the data.
