环境监测设备的检定/校准、结果确认及评价与期间核查探究

The exploration of environmental-monitoring-equipment’s verification/calibration,confirmation and period verification

仪器设备检定/校准、结果确认及评价与期间核查工作是环境监测仪器设施设备管理的重要组成部分,是保证仪器准确度和精密度的有效手段。依据《紫外、可见、近红外分光光度计检定规程》(JJG 178—2007)及仪器说明,并参阅相关标准,结合实验室条件和仪器特点,对TU-1901双光束紫外可见分光光度计的检定结果开展确认及评价、期间核查,以此保证设备在两次检定周期内保持检定状态的可信度及量值的稳定性,满足监测质量要求。

Verification/calibration,result confirmation and evaluation,and period verification work were an important part of the management of environmental monitoring equipment,it was an effective means to ensure the accuracy and precision of instruments.According to the JJG 178—2007“Verification Regulation of Ultraviolet,Visible,Near-infrared spectrophotometers”,the instrument description of TU-1901 UV-visible Spectrophotometer,the relevant standards,combined with laboratory conditions and instrument characteristics,the TU-1901 dual-beam UV-visible spectrophotometer was analyzed.The confirmation and evaluation of the photometer verification results,and the period verification,so as to ensure the reliability of the equipment to maintain the verification state and the stability of the value during the two verification cycles.It aims to meet the environmental monitoring quality requirements.
