VOC Analysis & SVOC Analysis

06 Jan VOC Analysis & SVOC Analysis

Identification & Quantification

 

VOC Analysis (volatile organic compounds) identifies and quantifies volatile compounds. VOCs are organic chemicals that can be naturally-occurring or man-made.

VOCs or volatile organic compounds are released as gases, often from consumer and industrial coating products. Government and industry standards have been put in place in order to restrict human and environmental exposure to these compounds, which are harmful. The EPA defines VOCs as:

“Any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, which participates in atmospheric photochemical reactions, except those designated by EPA as having negligible photochemical reactivity.”

Products that are commonly tested for the presence of VOCs include coatings, adhesives, paints, elastomers, and sealants.

 

VOC Analysis (Volatile Organic Compounds)

At UIS Organic Laboratory, our VOC analysis capabilities include:

  • Identification of VOCs
  • Content of VOCs
  • Analysis of volatile organic compounds in air (passive samplers)
  • VOC content of paints and coatings – ASTM D3960-05
  • Volatile content of coatings – ASTM D2369
  • Fingerprinting of volatile organic compounds
  • VOC Emissions testing
  • VOCs in plastics and polymers
  • VOCs in pesticides.

 

UIS Organic Laboratory has the capability to perform VOC Analysis on solvent-based, exempt solvent and water-based samples.

 

SVOC Analysis (Semivolatile Organic Compounds)

 

According to the EPA:

“A semivolatile organic compound is an organic compound which has a boiling point higher than water and which may vaporize when exposed to temperatures above room temperature. Semivolatile organic compounds include phenols and polynuclear aromatic hydrocarbons (PAH).”

SVOCs are incorporated into certain products to give them specific properties. Some examples include plasticisers (phthalate esters), which make plastics soft and flexible, and flame retardants (PBDEs), however there are a number of commercial uses for them. SVOCs are also used for grease-resistant food packaging, stain repellents and water repellents.

UIS Organic Laboratory is a SANAS-accredited environmental laboratory based in Pretoria, South Africa. Our testing capabilities include VOC Analysis and SVOC Analysis. For more information, please contact us:
