电感耦合等离子体光谱仪的保养:

The maintenance of inductively coupled plasma spectrometer:

(1)气体控制系统:ICP的气体控制系统是否稳定正常地运行,直接影响到仪器测定数据的好坏,如果气路中有水珠或其它固体杂质等都会造成气流不稳定,因此,对气体控制系统要经常进行检查和维护。首先要做气体密封试验,开启气瓶及减压阀,使气体压力指示在额定值上,然后关闭气瓶,观察减压阀上的压力表指针,应在几个小时内没有下降或下降很少,否则说明气路中有漏气现象,需要检查和排除。

(1) the gas control system: ICP gas control system is stable in normal operation, directly affect the determination of the quality of the data, if there is water or other solid impurities in the gas path will cause the flow instability, therefore, the gas control system to carry out regular inspection and maintenance. The first thing to do gas seal test, open the gas cylinder and the pressure relief valve, the gas pressure indicator in the ratings, and then close the cylinder, observe the valve on the pressure gauge pointer should not drop or fall, rarely in a few hours, otherwise the leakage phenomenon in the gas path, need to check and troubleshooting.

(2)使用环境:电感耦合等离子体光谱仪与其它大型精密仪器一样,需要在一定的环境条件下运行,否则,不仅影响仪器的性能,甚至造成损坏,缩短寿命等。根据光学仪器的特点,对环境温度和湿度有一定要求。如果温度变化太大,光学组件受温度变化的影响就会产生谱线漂移,造成测定数据不稳定;而如果环境湿度过大,仪器的光学部件,特别是光栅容易受潮损坏或性能降低

(2) the use of the environment: inductively coupled plasma atomic emission spectrometer and other large-scale precision instruments, need to run under certain environmental conditions, otherwise, not only affects the performance of the instrument, or even cause damage, shorten the life. According to the characteristics of optical instruments, the environmental temperature and humidity have certain requirements. If the temperature change is too large, the impact will be affected by temperature change of the optical components of spectral line shift caused by measured data instability; and if the humidity is too large, optics instrument, especially grating easy to damp damage or reduced performance

(3)每月用超声波清洗雾化室、炬管、样品喷射管;

(3) a month with ultrasonic cleaning spray chamber and the torch tube, sample injection pipe;

(4)每四个月更换光谱仪上的风扇过滤网;

(4) fan filter on the spectrometer for every four months;

(5)测试有机样品后用软布清洁炬室,防止有机成分沉积;

(5) test of organic samples with a soft cloth to clean the torch room, to prevent the organic components of the sediment;

(6)进样管、蠕动泵管、废液管、垫圈等消耗品根据使用情况及时更换;

(6) sampling tube and peristaltic pump tube, waste pipe, gasket and other consumables according to the use of timely replacement;

(7)每年根据仪器企业提供的日常维护条款对仪器做全面保养。

(7) in accordance with the provisions of the daily maintenance of the instrument company to do a comprehensive maintenance of the instrument.

所以使用电感耦合等离子体光谱仪一定要好好保护仪器,要合理的进行保养与注意,出现故障就不要用了,有问题就要进行修理。

So the use of inductively coupled plasma spectrometer must be a good protective equipment, to a reasonable maintenance and attention, there is no need to use the fault, there is a problem to be repaired.

电感耦合等离子体光谱仪注意事项: 送样要求:液体,来样标明名称、主要成分、待测元素大致含量。

Inductively coupled plasma spectrometer matters needing attention: sample delivery requirements: liquid, to indicate the name of the sample, the main component, the approximate content of the element to be measured.

样品要求:

Sample requirement:

(1)试液需完全澄清。

(1) solution to fully clarify.

(2)试液需pH≤7,盐酸或硝酸浓度≤10%。

(3)试液中基体元素含量不得超过待测元素一万倍。

(3) the content of matrix in the test shall not exceed ten thousand times the measured elements.

(4)试液中若含有有机物必须作硝化处理后上机测定。

(4) if the solution containing organic matter determination must operate nitrification.

(5)样品量:根据仪器要求

(5) sample size: according to the requirements of the instrument
