气密性检测设备长假后开机使用要注意什么?

1. 在ICP开机前和过程中,务必翻开空调保证室温固定在22℃,以免光学元件受温度变化影响产生谱线漂移,形成测定数据不稳定。
1. Before and during the start-up of ICP, it is necessary to turn on the air-conditioner to ensure that the room temperature is fixed at 22 C, so as to avoid the spectral drift of optical elements affected by temperature changes and unstable measurement data.
2.在ICP开机前和过程中,视状况翻开抽湿机,确保室内湿度控制在45%~60%之间,以免过大的湿度影响高频发射器,轻则等离子体不易点燃,重则高压击毁元件,损坏高频发射器及电路主板。
2. Turn on the dehumidifier according to the condition before and during the start-up of ICP to ensure that the indoor humidity is controlled between 45% and 60%, so as to avoid excessive humidity affecting the high-frequency transmitter, light plasma is not easy to ignite, heavy high-voltage destroys components and damages the high-frequency transmitter and circuit motherboard.
3.在ICP开机前和过程中要翻开抽风系统,扫除工作时产生的有毒气体,防止有毒气体留在室内,对人员安康形成危害。

3. Before and during the start-up of ICP, the exhaust system should be turned on to clean up the toxic gases produced during the work, so as to prevent the toxic gases from remaining indoors and causing harm to people's health.
4.要经常除尘和防尘。在断开电源的状况下,用枯燥干净的纱布或者小毛刷或者吸尘器将各个部位的积尘清算洁净。
4. Dust removal and prevention should be frequent. When the power supply is disconnected, the dust deposits in various parts are cleaned by dry and clean gauze or small brush or vacuum cleaner.
5.ICP要运用高纯氩气,纯度请求99.99%以上,以免形成点不着火或者ICP熄灭。
5. ICP should use high purity argon with purity over 99.99% to avoid ignition or ICP extinguishing.
6.ICP工作中确保气流稳定。留意不要让管子弯曲太凶猛,以免载气流量不稳定形成脉动,影响测定。并且在ICP工作中经常察看减压阀,保证氩气压力在0.6~0.7MPa。
6. Ensure airflow stability in ICP work. Be careful not to bend the pipe too fiercely, so as to avoid the fluctuation of carrier gas flow and influence the measurement. In ICP work, pressure relief valves are often inspected to ensure that the argon pressure is between 0.6 and 0.7 MPa.
7.要定期清洗雾化器和炬管。特别是测定高盐溶液之后,不及时清洗,会形成 雾化器梗塞,炬管喷嘴积有的盐分会形成气溶胶通道不正常。要定期用稀硝酸、去离子水洗。
7. Clean atomizer and torch tube regularly. Especially after the determination of high salt solution, if it is not cleaned in time, the atomizer obstruction will be formed, and the aerosol channel will be abnormal if the salt accumulated in the nozzle of the torch tube. Wash regularly with dilute nitric acid and deionized water.
8.开机测定前,要事前布置好各项准备工作,切忌短暂的时间距离里开开停 停,防止仪器频繁开启形成损坏。由于仪器每次开机时,瞬时电流大大高于正常工作电流,瞬时的脉冲冲击容易形成功率灯丝断丝,碰及短路等。
8. Before startup test, all preparatory work should be arranged beforehand. Do not start or stop in a short time interval to prevent damage caused by frequent opening of the instrument. Because the instantaneous current is much higher than the normal working current when the instrument is turned on each time, the instantaneous impulse impulse is easy to cause the power filament to break, touch and short circuit.
9.每次完成实验,确保样品溶液、规范溶液远离仪器,减少挥发对仪器的腐蚀。
9. Complete the experiment every time to ensure that the sample solution and standard solution are far away from the instrument and reduce the corrosion of volatilization to the instrument.
10.循环冷却水要用蒸馏水,避免结垢。
10. Distilled water should be used for circulating cooling water to avoid scaling.
11.长时间不运用时,每周要开机一次,每次至少到达30min以上。
11. When not in use for a long time, turn on the machine once a week, at least 30 minutes at a time.
