楼主,我也是pe 5300dv,测玩具重金属的
雾化器压力是正常的。你的1PPm的Mn校准观测强度是多少?我的大概是8w到10w。1pm Mn标液开描光的话大概33w
还是你看看是不是雾化效果不好,要不做个钠锥看看
就是强度不高, 1ppm的锰在20w 以下, 仪器说明书 不是说10ppm 的锰 要在300w以上吗
那你的也Mn强度也不高哦,
另外钠锥是什么
Sodium Bullet Test
To run the sodium bullet test:
1. For aqueous analyses, aspirate a 1000 mg/L solution of sodium. For organic
analyses, aspirate an appropriate organic blank.
2. Examine the plasma through the viewing window in the sample compartment
door.
A yellow-orange bullet (or green, in the case of organic compounds) should be
visible in the center of the discharge, and should extend from the base of the
discharge to about 2-3 mm above the top of the RF coil. If the bullet height is
unsatisfactory, adjust the nebulizer argon flow in the Method Editor or Plasma
Control windows.
If no bullet appears or the bullet is faint:
Check that your sample does contain sodium at the required concentration.
Check that sample is being pumped to the nebulizer. Make sure that the pump
lever is engaged and that the pump tubes are connected appropriately.
Check that the drain is being pumped properly. You should see a segmented
flow of bubbles through the tubing.
10个ppm的是300w,那我1个ppm的是30w,差不多了

雾化器效果如何?
雾化效果如何看? 背压108左右 算正常。
好的, 明天我试试 多少算正常呢
信号强度低也不一定是雾化效率差的原因吧,最主要的可能还是炬管、光路入口那里脏了,反正我是洗洗就上去了

所有问题都解决了,检测器有木有问题,老化什么这类的?
我是使用仪器的 这个我还真不了解,不过 应该也差不多老化了
长期处于恶劣的环境,维护保养不到位,就有问题
诶! 你们日常维护有哪些项目呢
清洗进样系统,比如矩管,雾化器,温湿度要达到要求,防灰尘。。。。。。。。

钠锥,是看等离子体的位子吗?

有些项目不用每天这样频繁的做啊!
差不多啊,我差不多每天也是这样做的

形象化的清楚进样系统的情形,知道有没有堵
