本次偏差由于文件规定不够详细和人员疏忽引起。于 2020.01.19纠

This deviation was caused by insufficient detail in the documents and negligence of personnel. Re-calibration after correction on 2020.01.19, the result is qualified, and there is no risk for product testing. The last cleaning time of the atomizer and combustion head of this equipment is 2020.12.23. It is necessary to review the samples tested by the flame method after this time. The results show that there is no risk for sample testing. In order to better guide the daily calibration operations of metrology personnel, it is planned to upgrade the program H0-TM-21336 "PinAAcle 900T Atomic Absorption Spectrometer Calibration Program", add relevant regulations for cleaning and maintenance of the instrument before annual calibration, and provide training for personnel . In order to better maintain the instrument, plan to upgrade the program H0-TM-22132 "PinAAcle 900T atomic absorption spectrometer operation and maintenance procedures", refine the cleaning method of the combustion head and increase the atomizer cleaning method and cleaning cycle, etc., and carry out the relevant personnel Training.

The deviation is caused by the lack of detailed documents and negligence of personnel. Re check after rectification on January 19, 2020, the results are qualified and there is no risk for product detection. The last cleaning time of atomizer and combustion head of this equipment is December 23, 2020. It is necessary to review the samples detected by flame method after this time of the instrument. The results show that there is no risk for sample detection. In order to better guide the daily calibration operation of Metrology personnel, it is planned to upgrade the version of h0-tm-21336 "calibration procedure of pinaacl 900t atomic absorption spectrometer", and add relevant regulations on cleaning and maintenance of instruments before annual verification, and train personnel. In order to better maintain the instrument, the updated program h0-tm-22132 "operation and maintenance procedure of pinaacl 900t atomic absorption spectrometer" is planned, the cleaning method of combustion head is refined, and the cleaning method and cleaning cycle of atomizer are added, and relevant personnel are trained.<br>

This deviation is caused by the lack of detailed documents and negligence of personnel. After correction on January 19, 2020, it was re-checked, and the result was qualified, which had no risk to product inspection. The last cleaning time of atomizer and burner of this equipment is December 23rd, 2020. It is necessary to review the samples detected by flame method after this time, and the results show that there is no risk for sample detection. In order to better guide the daily calibration operation of metrological personnel, it is planned to upgrade the program H0-TM-21336 "Calibration Procedure for PINAACLE 900T Atomic Absorption Spectrometer", add relevant regulations such as cleaning and maintenance of instruments before annual calibration, and train personnel. In order to better maintain the instrument, it is planned to upgrade the program H0-TM-22132 "Operation and Maintenance Procedures of PINAACLE 900T Atomic Absorption Spectrometer", refine the cleaning methods of the combustion head, increase the cleaning methods and cleaning cycles of the atomizer, and train relevant personnel.
