Question
Select all of the following statements that are TRUE.
Answer
1.
The primary combustion region of a flame atomization source is generally the most useful region for atomic absorbance measurements.
2.
Electrothermal atomizers use less sample than a flame atomization source.
3.
Electrothermal atomizers have better precision than flame and plasma atomization sources.
4.
Atomization by hydride generation works by bubbling hydrogen gas through the sample solution to create volatile hydride species.
5.
In glow-discharge atomization, neutral sample atoms are ejected from the cathode surface by accelerated gas ions.
6.
Arc, spark, and laser ablation all require the sample to be conductive, or mixed with a conductive material prior to atomization.
7.
In an inductively coupled plasma (ICP) source, an induction coil powered by a radio-frequency generator generates a fluctuating magnetic field. The field interacts with the electrons and ions and cause them to flow in closed annular paths to generate current.
