Accurate and reliable BTEX testing is crucial for producers of uncountable products, from paints and adhesives to leather products and plastics. Not only is accruate analysis a critical step in preventing exposure and contamination that can affect human health and the environment, but it is a necessary part of complying with EPA guidelines and the Florida Administrative Code. Partnering with a knowledgeable and competent environmental services laboratory is key to staying on top of your BTEX emissions.
Methods of BTEX testing
There are several methods of testing for BTEX compounds, including gas chromatography (GC) or with photo-ionization detector. Samples can come from air, water, or soil.
When undergoing a GC analysis, headspace sampling allows the VOCs to be analyzed without first undergoing a sample extraction. The sample is placed in a sealed vessel before being warmed. The heat brings the compounds into a state between liquid and gas. A sample is then removed from the atmosphere and introduced into the port of the GC. This static headspace method is ideal for aromatic samples, pharmaceuticals, resins, and petroleum.
A photo-ionization analysis detector (PID) is a a simple, straightforward, and less expensive method of measuring BTEX compounds. It is a non-destructive method that responds differently to aromatic hydrocarbons than to other gas components.
To perform a PID analysis, the BTEX compounds are separated from the remaining compounds with a trap and purge that takes advantage of their differences in solubility and volatility.
By identifying BTEX contamination, the producer can take the critical steps needed for remediation.
Main sources of BTEX contamination
BTEX – Benzene, Toluene, Ethylbenzene, and Xylene – occur naturally but these petroleum derivatives have toxic effects that are exacerbated by their water solubility and polarity parameters. Contamination occurs when these VOCs are released in an expected way, like through emissions, or leaked accidentally, such as through underground storage tank ruptures, oil spills, or refinery leaks.
BTEX emissions can be prevalent in seemingly unlikely trades – even nail salons release amounts of toluene through high-volume use of polish. But the compounds are released in significantly greater volumes in industries including:
- Industrial manufacturing
- Oil refining
- Paints and adhesives
Consulting with a dedicated environmental services laboratory allows a producer, manufacturer, or handler of BTEX compounds to gain a complete and accurate picture of their exposure and emissions.
