In reply to mary. AAS lamps must be used regularly. If you do not use them they will still stop working properly.

I have a multi hollow cathode lamp with six elements and recently when I want to measuring nickel sometimes I have problem?
is there problem with lamp? I don’t measuring nickel every day and recently I just used it for several times, but I used this lamp for measuring iron in my sample that it was aproximately a lot.
is there any chance to damaging the nickel cathode because iron and nickel are on the same lamp?
could you please help me?
and another question, What is the dust on the inner glass hollow cathode lamp? are there this dust on a new lamp that we purchasing from market or just second hand one?

In reply to Donatus Akao. I am in agreement with you. The sensitivity of a sinle element lamp is significantly higher than multi-element lamp for reasons already expressed by you.

Thank you for sharing your experience Dr. I must say that one of the disadvantages of using a multi element HCL is compromised intensity. I have used some at times some of these element coded in the lamp will not all emit enough intensity to optimize in preparing for analysis. These happens mostly when the shelf life is about halve. What do you have to say about this.
