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 information can be obtained with ICP-MS? (There can be one or more correct answers)
Lead isotope ratios of the sample
The concentration of organic binders in the sample
The concentration of metals in the sample
Carbon isotope ratios of the sample
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 to a few hundred milligrams
A few grams
What are the limitations of ICP-MS analysis? (There can be one or more correct answers)
Solid samples must usually be dissolved
Poor sensitivity of the technique
Solid samples can not be analysed
A large sample size is required
The analysis is destructive or semi-destructive
Which of the following statements about LA-ICP-MS is correct? (There can be one or more correct answers)
It is a non-destructive method
The sample size is limited by the size of the ICP-MS
Reference material with suitable composition is needed
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)
The method cannot be used to quantify N and O
This method cannot analyse solids
It vaporizes too fast
It is possible in theory, but it would take too much time
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
