我们曾在本刊1987年第二期上叙述了我所 ICAP-9000型等离子体光谱仪器四年中使用的情况和一些粗浅感受。文中指出随着仪器使用时间的增长,由于使用环境和条件的限制,仪器的性能逐渐下降。因此,对国内无维修站的仪器,操作者若能进行某些简单维修,是保证仪器正常工作的重要一环。本文将叙述减缓标准化后元素标准曲线斜率和截距变大采取的一些措施。 In our second issue, 1987, we described the conditions and some superficial feelings that have been used in our ICAP-9000 plasma spectrometer for four years. The article pointed out that as the use of equipment, the growth of time, due to the use of the environment and conditions, the performance of the instrument gradually declined. Therefore, the domestic non-maintenance station equipment, the operator if some simple maintenance, is to ensure the normal operation of an important part of the instrument. This article describes some of the measures taken to slow the normalization of the slope and intercept of the standard curve.
