All of the Following Are Background Correction Techniques for Atomic

question 5

Multiple Choice

All of the following are background correction techniques for atomic spectroscopy,except:

• A)subtraction of adjacent pixel height from signal pixel height for a charge injection detector.
• B)a rotating beam chopper periodically blocks the analyte signal,allowing for a background measurement.
• C)the absorbance and scattering of the light from a D₂ lamp is measured and subtracted from the absorbance and scattering of light from a hollow-cathode tube.
• D)the analyte sample is spiked with a compound to absorb all background signal.
• E)a strong magnetic field is pulsed on and off.The sample and background is observed when field off.Only the background is observed when the field is on.The absorbance difference is the analyte signal.

Definitions:

Instinctive Drift

The tendency of an animal's learned behavior to revert to its instinctual behaviors over time, interfering with conditioned responses.

Operant Behavior

Operant behavior is a type of learning where behavior is controlled by consequences, including reinforcements and punishments.

Continual Reinforcement

A reinforcement schedule in which a behavior is reinforced every time it occurs, leading to rapid learning.

Flavor Aversions

The learned avoidance of a particular food or taste after a negative experience, associating it with illness or discomfort.
