I am relatively new to the business of atomic spectroscopy in general and single particle analysis in particular. Therefore I hope that I will be forgiven for asking stupid questions.
I am currently trying to set up an ICP-MS 7900 with ISIS as a Sample Introduction System for Single Particle Analysis. The method wizard asks for the inner diameter (ID) of the pump tube to calculate the sample inlet flow. Here I am unfortunately a little bit over-question, from which tube the diameter is meant. Theoretically, I would assume that the flow from the 6-way valve into the nebulizer is relevant and therefore also this tube diameter. Unfortunately, I also have no information on the diameters of the installed hoses. Do standard values exist here?
I would be happy if someone could help me here.
