目前火焰原子吸收分光光度计,虽然在电路、光路设计、工艺加工上颇赞一翻心思,尽量减少仪器在测量过程中读数的漂移,以提高仪器的测量精度。但是在实际测量过程中,仪器测量的条件仍然不可能是一成不变的,其中除乙炔,空气流量的变化易产生读数的漂移外,燃烧器的热平衡和电路、光路系统受温度的影响等,都可能造成读数的漂移。这就给测试者在测定的时候,尤其是大批试样测定时带来麻烦。我们沿用先测标准系列,继而测定一批试样,然后再抽查2、3个标准点是否与起始测量的数据相符,以保证测
Flame atomic absorption spectrophotometer, although in the circuit, optical design, process processing quite like overwhelmed, try to reduce the drift of the instrument readings in the measurement process to improve the measurement accuracy of the instrument. However, in the actual measurement process, the instrument measurement conditions still can not be static, in addition to acetylene, the change of air flow is easy to produce reading drift, the heat balance of the burner and the circuit, the optical system affected by the temperature, etc., may Cause the reading drift. This gives the tester trouble at the time of measurement, especially when a large number of samples are measured. We follow the first test series of standards, and then determine a number of samples, and then spot check 2,3 standard points consistent with the initial measurement data to ensure that test
