What is the first step in the AAS process?

• Light emission
• Data analysis
• Atomization of the sample
• Sample preparation

In AAS, what happens during the atomization step?

• Atoms are broken down into individual particles
• The sample is dissolved in a liquid
• Light is emitted through the sample
• The concentration of elements is measured

Which of the following best describes the relationship between light absorption and element concentration in AAS?

• Higher absorption indicates higher concentration
• Lower absorption indicates higher concentration
• Absorption is unrelated to concentration
• Higher absorption indicates lower concentration

What is the primary function of the hollow cathode lamp in Atomic Absorption Spectroscopy?

• To detect the intensity of light
• To emit light at specific wavelengths
• To measure the concentration of elements
• To prepare the sample for analysis

Which component of AAS isolates the specific wavelength of light for measurement?

• Hollow Cathode Lamp
• Atomization Source
• Monochromator
• Detector

What is the purpose of the detector in AAS?

• To isolate specific wavelengths of light
• To prepare the sample for analysis
• To measure the intensity of light passing through the sample
• To emit light at specific wavelengths

In which field is AAS commonly used to measure heavy metals?

• Clinical testing
• Environmental analysis
• Pharmaceutical development
• Food safety

Which of the following statements about AAS is true?

• AAS is not sensitive to low concentrations.
• AAS is primarily used for measuring metals.
• AAS can analyze both metals and non-metals.
• AAS requires no calibration for accurate results.

What is one limitation of Atomic Absorption Spectroscopy?

• It primarily measures metals only
• It requires no calibration for accurate results
• It can analyze both metals and non-metals
• It is not sensitive to low concentrations

How does AAS compare to other analytical techniques?

• AAS is less sensitive than most techniques.
• AAS can measure a wider range of elements.
• AAS is preferred for non-metal analysis.
• AAS is highly specific for metal analysis.
