Which component of a spectrophotometer converts electromagnetic radiation into an electrical signal?
A. Recorder
B. Sample holder
C. Monochromator
D. Detector
Detector
What is a detector?
The sample holder holds the sample, while the detector in a spectrophotometer converts radiation into an electrical signal for analysis. It plays a crucial role in measuring light intensity.
Which term describes the state where an individual experiences physical discomfort and distress upon reducing or stopping drug use after prolonged exposure?
A. Relapse Prevention
B. Tolerance Development
C. Withdrawal Sickness
D. Addiction Cycle
C. Withdrawal Sickness
What is relapse prevention?
Relapse Prevention focuses on avoiding returning to drug use.
What is withdrawal sickness.
Withdrawal Sickness refers to the physical discomfort when reducing or stopping drug use after prolonged exposure.
What is the purpose of a detector in gas chromatography?
A. To separate components in the column
B. To develop signals that activate the recorder for making a permanent record of separation
C. To introduce the sample into the column
D. To heat the injection chamber
B. To develop signals that activate the recorder for making a permanent record of separation
Which regulatory body in the United States is responsible for enforcing the Controlled Substances Act and regulating the manufacturing, distribution, and dispensing of controlled substances?
A. National Institutes of Health (NIH)
B. Centers for Disease Control and Prevention (CDC)
C. Food and Drug Administration (FDA)
D. Drug Enforcement Administration (DEA)
Drug Enforcement Administration (DEA)
What is the DEA?
The Food and Drug Administration (FDA) focuses on drug safety and approval, not enforcement of controlled substances. The Drug Enforcement Administration (DEA) enforces the Controlled Substances Act.
What allows gas chromatography to rapidly separate complex mixtures into individual compounds?
A. Nitrogen gas flow through the injector
B. Heated injection chamber
C. Carrier gas
D. Thin film of liquid in the column
Thin film of liquid in the column
What is gas chromotography?
Nitrogen gas flow through the injector helps vaporize samples, not separate compounds. Gas chromatography separates mixtures using a thin film of liquid in the column, allowing for rapid separation.
Under which legislation does Canada regulate the possession, production, and distribution of controlled substances?
A. Health Canada Regulations Act
B. Controlled Drugs and Substances Act
C. Canadian Food and Drugs Act

A. Hallucinogens
B. Club Drugs
C. Synthetic Opiates
D. Narcotics
Hallucinogens
In gas chromatography, what role does the recorder play in the analysis process?
A. It makes a permanent record of the separation by tracing peaks on the chromatograph
B. It separates the components of the sample
C. It identifies the concentration of each compound
D. It introduces the sample into the column
It makes a permanent record of the separation by tracing peaks on the chromatograph
What does the recorder do in GC?
The recorder in gas chromatography does not identify compound concentrations. Its role is to create a permanent record by tracing peaks on the chromatograph for analysis.
Which category of drugs acts to slow down the central nervous system and reduce brain activity?
A. Stimulants
B. Hallucinogens
C. Anabolic Steroids
D. Depressants
D. Depressants
