直读光谱仪标准样品及标准化对仪器准确度的影响

Influence of standard sample and standardization of direct reading spectrometer on instrument accuracy

1、人员培训。检测精度与操作人的习惯有很重要的关系，所检测人员必须经过专业培训，熟练掌握操作方法后才可上机操作。检验人员必须有相应的资格证明，熟悉国家标准和国标的允许误差范围。

1, personnel training. Detection accuracy and operator's habits have a very important relationship, the test personnel must be trained professionally, proficient in operating methods before the machine can operate. The inspector must have the corresponding qualification certificate and be familiar with the permitted error range of the national standard and the national standard.

2、电极，适配器，橡胶圈等属于消耗品，要做到定期检查，发现不符立即更换，日常的仪器维护也很重要，它直接影响仪器分析的准确性，这点是保证仪器分析准确性的一个重要环节。

2. Electrodes, adapters, rubber rings and other consumables, to do regular inspection, found out that the inconsistency immediately replaced, daily instrument maintenance is also important, it directly affects the accuracy of instrument analysis, this is an important link to ensure the accuracy of instrument analysis.

3、每次测量结束后，一定要认真查看燃烧点是否正常，如发现扩散放电需重新检测。

3. After each measurement, we must carefully check whether the burning point is normal or not, such as diffuse discharge found to need to re-test.

4、每测量20次左右时应休息一会设备，设备在温度较高的环境下测量时因该增加休息次数，一面高温下损坏仪器，影响测量结果，在开关机时注意间隔时间应在5分钟以上。

4. Every 20 measurements should rest for a while equipment, equipment in high temperature environment measurements due to the increase of the number of breaks, one side of the high temperature damage the instrument, affecting the results of measurement, when the switch should pay attention to the interval of more than 5 minutes.

5、打磨不同基体的试样应更换砂纸，尽量避免基体时间的污染，做曲线时也要注意。

5. Sand paper should be replaced when grinding the samples with different substrates, so as to avoid the contamination of substrate time as far as possible, and attention should also be paid to curve making.

6、废气排放管路需要定期清理，清洗方法：调试氩气流量开到最大，防止清理管路时废气进入氩气管路形成污染，取下胶皮管，把废气排出，注意安装胶皮管时应用硅子封闭。

6. Waste gas discharge pipeline needs regular cleaning, cleaning methods: debugging the argon flow to the maximum, to prevent the cleaning pipeline waste gas into the argon gas pipeline pollution, take off the rubber hose, the exhaust gas discharge, pay attention to the installation of rubber hose sealed with silicon.
