Volatile Organic Compound (Voc) Testing

Importance of VOC Testing Labs In India

Volatile Organic Compounds (VOCs) are compounds of carbons that are known for having a substantially high vapour pressure and low water solubility when they are exposed to ordinary room temperatures. VOCs can be both human-made or can occur naturally. VOCs are employed and produced in the paints, pharmaceuticals, and refrigerants manufacturing industries. But even in our daily lives, we are surrounded by VOCs without realizing it. Some of the products that expose us to VOCs are cosmetics, perfumes, air fresheners, and the smell of freshly painted walls. Not just these, in a typical household, there could be many potential sources of VOCs, such as carpets, furniture, etc. In fact, it is stated that the levels of VOCs are two to one

thousand times higher indoors than outdoors. This implies that a person is more susceptible to being exposed to VOCs indoors in comparison to outdoors. And even though some VOCs might have an odour, a lot of them are odourless and hard to detect without proper testing.

But the importance of getting these VOC concentrations tested arises from the fact that these compounds are toxic when present in high concentrations. High concentrations of VOCs can cause some serious health complications and are even associated with a condition known as ‘Sick Building Syndrome’.

What is VOC Testing

VOCs are compounds of carbon, which are toxic when consumed in high concentration or for a long period of time. These substances are regarded harmful because of their low boiling points, high toxicity, and high rate of halogenation. Despite these factors, these compounds are used in a lot of products such as solvents, cleaners, inks, paints, etc. These compounds are also found in drinking water and soil. But to ensure they do pose a threat to the health of the people around, tests are conducted to check the concentration of VOCs present in the air. These tests are essentially referred to as Volatile Organic Compounds (VOC) Testing.

The VOC testing is conductedmainly to check their presence in the air but these compounds can also be tested in drinking water, surface water, soil, and so on. Some of the common VOCs that are tested are acetone, benzene, ethylene glycol, formaldehyde, methylene chloride, perchloroethylene, toluene, xylene, 1, 3-butadiene. These compounds lead to health risks but the severity of symptoms depends on theamount and the composition of VOCs present in the air being tested. VOC tests help in finding out these answers andconsequently help in maintaining a safe concentration of these compounds in both indoor and outdoor spaces.

Testing Parameters For VOC Testing At Anacon

VOC Testing is performed to test for toxic carbon compounds one of the most common being formaldehyde. The primary parameters which are considered during VOC testing are
1. The emission rate
2. The concentration
3. The duration of emission

With the help of these three parameters, the reference parameters such as the initial emitted concentration, the diffusion coefficient, and the partition coefficient are calculated. These standard reference parameters prove useful for conducting the indoor as well as the ambient air’s VOC emissions tests.

Why Choose Anacon For VOC Testing

Anacon Laboratories provides testing solutions that facilitate the monitoring of VOCs in both indoor and ambient air samples. We perform these tests at high levels of accuracy and offer a quick result turn-over time as well. We also check for other pollutants of VOC, namely Bromodichloromethane, Bromoform, Chloroform, Dibromochloromethane, and total Trihalomethanes. To test these compounds we only use modern testing methods and equipment such as Desorption Gas chromatography / Mass spectroscopy (TD-GC/MS), High-Pressure Liquid Chromatography (HPLC), and so on.
