What is an E-cigarette ?
An e-cigarette is an electronic product designed to mimic the traditional cigarette, offering a similar appearance, smoke, flavor, and sensory experience.
The primary components of an e-cigarette include e-atomizing liquid (containing nicotine, flavorings, and propylene glycol), a heating system, power supply, and filter. When heated and vaporized, it produces an aerosol with specific odors for users.
Why Conduct E-cigarette Testing?
E-cigarettes pose health risks and are not a healthy alternative. They contain harmful substances like nicotine, which can lead to chronic lung diseases such as chronic obstructive pulmonary disease (COPD) and chronic bronchitis. Additionally, e-atomizing liquids contain chemicals like propylene glycol, glycerol and heavy metals, further endangering health.
Regulatory requirements: Many countries and regions strictly regulate e-cigarettes.
Key Testing Areas for E-cigarettes:
1.E-atomizing liquid Testing:
Example procedure: Nicotine testing (following the “Safety Technical Specification for E-liquids”): measure the liquid, place it in a volumetric flask, add isopropanol to reach a fixed volume, extract through oscillation, and analyze the sample.
2.Harmful E-cigarette Emissions Testing:
Example procedure (based on GB 41700-2022): collect emissions, transfer them to a container, add pyridine and acetonitrile, filter through a PTFE membrane, and perform analysis.
3.E-cigarette Device Testing:
Example procedure (for leak prevention, follow GB 41700-2022): We place an e-cigarette or cartridge filled with e-liquid on absorbent paper for at least 6 hours and observe for any signs of liquid leakage.
Why Protective Measures During Testing?
1.Inhalation Risks from Volatile Organic Gases:
During aerosol testing, preparing standard solutions and sample handling may involve volatile organic chemi cals like methanol, acetonitrile, acetone, pyridine, and isopropanol. Exposure or inhalation can cause irritation and even organ damage. In the case of device testing, inadequate e-cigarette design can lead to irritating odor release due to liquid leakage.
2.Inhalation Risks from Carcinogenic Aerosols:
During emissions testing, accidental leaks can result in harmful substances (such as formaldehyde, acetalde hyde, acrolein, and heavy metals) being released into the laboratory air, posing health risks to personnel.
3.Chemical Storage Risks:
Storing various chemicals with diverse properties requires careful management to prevent accidents.
