A sample is sent to ICP-MS for quantitative analysis. How much material is needed? (There can be one or more correct answers)
The amount depends on the sample and the elements of interest
A few nanograms
A few grams
A few to a few hundred milligrams
Which of the following statements about LA-ICP-MS is correct? (There can be one or more correct answers)
Reference material with suitable composition is needed
The sample size is limited by the size of the ICP-MS
It is a non-destructive method
All sample sizes can be analysed
Why is it not possible to quantify HNO3 in a liquid with ICP-MS? (There can be one or more correct answers)
It vaporizes too fast
It is possible in theory, but it would take too much time
This method cannot analyse solids
The method cannot be used to quantify N and O
What information can be obtained with ICP-MS? (There can be one or more correct answers)
Carbon isotope ratios of the sample
The concentration of organic binders in the sample
Lead isotope ratios of the sample
The concentration of metals in the sample
How are solid samples typically analysed in ICP-MS spectrometry? (There can be one or more correct answers)
Pyrolysed into a gas prior to analysis
Preparation is not needed
Directly with the use of Laser Ablation
By dissolving in appropriate liquid prior to analysis
What are the limitations of ICP-MS analysis? (There can be one or more correct answers)
Solid samples can not be analysed
Poor sensitivity of the technique
The analysis is destructive or semi-destructive
A large sample size is required
Solid samples must usually be dissolved
Which of the following statements is correct? (There can be one or more correct answers)
ICP-MS can only be used to analyse solids that dissolve in water
The ions are separated in the mass separation device according to their mass
ICP-MS provides information about the molecular structure of the material
ICP-MS is a destructive method of analysis
