2. 6 points My Notes This question deals with conception about Atomic Absorption. Read Chapter 21 in Harris and the Atomic Absorption lab before attempting this question What is the primary requirement for a sample to be used in Atomic Absorption? The sample must be clear The sample must be a solid The sample must be atomized during the analysis The sample must be colored What types of analytes are detected using Atomic Absorption? Room Temperature Gases Molecules OOrganic Molecules Non-metals Metals What type of light source is used for Atomic Absorption Spectroscopy? Tungsten Lamp Deuterium Lamp Hollow Cathode Tube Halogen Lamp Laser Submit Answer Save Progress

Explanation / Answer

1. during the atomic absoption analysis, sample must be atomized and then exited. For this exitation energy is absorbed.

so answer is the sample must be atomized during the analysis.

2. in AAS, we can detect the Metal percent in ppm or ppb in sample.

so Metals is the answer.

3. Hollow cathode lamps (HCL) are the most common radiation source in AAS.

Inside the sealed lamp, filled with argon or neon gas at low pressure.

so Hollow cathode tube is the answer.
