Thermo Scientific Orion 2110XP Ammonia Analyzer

General InformationOffline CalibrationThe offline calibration feature of the 2110XP analyzer allows the operatorto adjust the analyzer to values determined by alternate methods used intheir laboratory such as elemental spectroscopy and ion chromatography.The offline calibration is essentially a one point calibration. To perform anoffline calibration, a sample is taken from the bypass of the analyzer; thesample concentration value is stored in memory; the sample is analyzedby an alternate method of choice; the previously stored reading is adjustedto the lab method result; and the analyzer is then returned to the analysismode. The term “offline calibration” refers only to the fact that a samplefrom 2110XP analyzer bypass is taken “offline” for laboratory analysis; infact, no downtime is experienced during the procedure and the analyzerremains online throughout.Thermo Scientific Orion 2110XP Ammonia Analyzer User GuideI-6
