一、分析仪器要不要制订规程理化分析仪器中,有许多仪器均从测得量值为目的,毫无疑问,测得的量值结果,既存意义于量值的大小,同时也离不开量值的可信赖程度——准确度。分析仪器测得结果的准确程度,一方面取决于标定(或校准)仪器所用的标准物质有关参数标准值的准确程度;另一方面也取决于仪器的计量性能。当标准物质有关参数的标准值的误差远小于仪器测得结果的误差时,测得结
First, the analysis of equipment to develop procedures Physical and chemical analysis equipment, there are many instruments from the measured value for the purpose, no doubt, the measured value results, both existing in the magnitude of the magnitude of value, but also inseparable from the amount Reliability of value - accuracy. Analytical instruments to determine the accuracy of the results, on the one hand, depends on the calibration (or calibration) of the standard material used for the accuracy of the standard value of the relevant parameters; the other hand, also depends on the measurement performance of the instrument. When the error of the standard value of the relevant standard of the standard material is far less than the error of the measured result of the instrument, the measured knot
