Thank you very much for your iolite support. Yes, laser Thermo is used with the Icap device. I will try to solve the problem by examining your suggestion.
I want to get information about another subject. What could have happened to cause IVA failure? Because the laser system, which was working without any problems the day before, gave such an error the next day despite starting it with the same steps. I use sulfide and floating stage for my samples, and in this stage I manually adjust the heights of the samples so that the surfaces are flat and place them in the laser cell. The reason I ask this question is that even the slightest mistake in laser costs me months. If I can minimize the problems, the time I spend using laser will be shortened and I will focus on the remaining parts of my work. Another reason is that I want to share the reason for this error with the lab coordinator and my own PI so that the same mistakes do not occur again in the future and this does not cause financial and time loss.
