Vinyl Chloride Determination: Monitoring a Carcinogenic Substance

Why Determination of Vinyl Chloride?

What is Vinyl Chloride?

Vinyl chloride (VC) is a colorless, toxic gas with a sweet odor used in the production of polyvinyl chloride (PVC) plastics. Vinyl chloride with the chemical formula C₂H₃Cl is used in the plastics industry as PVC raw material and in industrial solvents.

Vinyl chloride is both an important environmental and health pollutant, and exposure to high levels can lead to serious diseases such as cancer.

Why Determine Vinyl Chloride?

1. Health Risks: Long-term exposure to vinyl chloride increases the risk of liver cancer (angiosarcoma) in particular. It affects respiratory tract disorders and neurological disorders.
2. Legal Regulations: Limits for residues of vinyl chloride are regulated in the European Union, USA and other countries. Especially in food packaging, the maximum value is generally set at 1 µg/kg.
3. PVC Product Safety: Vinyl chloride residues should be monitored in food packaging or piping systems made of PVC.

What are the Methods for Determination of Vinyl Chloride?

1. Gas Chromatography (GC): Vinyl chloride in the sample is separated in gas chromatography and measured with a detector. It provides precise and accurate results. Widely used in industry standards.
2. Combination with Mass Spectrometry (GC-MS): Vinyl chloride separated by GC is detected by mass spectrometry. Effective in detecting low concentrations. Provides reliable results.
3. Fourier Transform Infrared Spectroscopy (FTIR): Analysis is based on the characteristic IR spectrum of vinyl chloride. Provides fast analysis. Can be measured directly in the gas phase.
4. Thermal Desorption Method: Vinyl chloride in the sample is desorbed by heating and analyzed by gas chromatography. It is especially suitable for low amounts of gases.

Vinyl Chloride Determination Application Areas

1. Food Packaging Testing: Vinyl chloride migration from PVC-based packaging into food is analyzed.
2. Industrial Products: Vinyl chloride residues are monitored in PVC pipes and other building materials.
3. Environmental Monitoring: Analyzes the environmental impact of industrial facilities that emit vinyl chloride.
