A technical paper by Olympian Water Testing specialists
Understanding VOCs and why it is important to test for them
The chemicals volatile organic compounds (VOCs) are a class of chemicals that are often present in the air we breathe and can have major effects on the quality of the air and on health. Here is a subtopic that will tell you all about VOCs science and why they are important for indoor air quality testing.
VOCs are organic compounds that quickly evaporate at room temperature and get into the air from paints, cleaners, and construction materials [1]. Most VOCs are quite odourous and smelly but others are inodorless and might not be detected [2].
VOCs with very high concentrations of the pollutants can be harmful to human health in the form of eye, nose and throat irritation; headaches; dizziness; and nausea [3]. Exposure to some VOCs in the long-term has also been associated with more serious diseases, including cancer and brain damage [4].
As VOCs have health effects, you should be testing the indoor air for their presence to detect sources of exposure and take measures to control air quality. There are different water VOCs test kits out there, with different strengths and weaknesses. Choose a suitable kit according to the VOCs you want to test for, accuracy and precision desired, and so on [5].
Finally, VOCs are a group of chemicals that can have massive effects on indoor air quality and human health. VOC testing can be used to pinpoint the potential sources of exposure and mitigate indoor air quality issues. There are many different VOC testing kits available in the market and you have to make sure you get the right kit for your situation.

Different types of VOC testing kits
VOC testing kits — There are different types of VOC testing kits on the market that are strong and weak. We’ll discuss in this subtopic about what VOC testing kits are available in the form of passive sampling kits, active sampling kits and continuous monitoring systems.
Passive sampling kits: A VOC test kit that is activated carbon or polymer sorbent that captures and separates VOCs from the air over a predetermined period of time [1]. — Passive sampling kits are simple to use, do not require external power or pumps, but results are not as precise as other VOC testing kits and can be sensitive to moisture and temperature [2].
Active sampling kits — are another type of VOC testing kit, in which a pump actively draws in a certain amount of air and flows it through a sorbent or other filter [3]. Active sampling kits tend to be more accurate than passive sampling kits and less affected by environmental factors, but need an external power supply and can be more expensive [4].
Continuous monitoring systems are a kind of VOC testing kit that continuously monitors VOCs in the air using sensors or other analyses [5]. Continuous monitoring systems can give you real-time VOC measurements, can track long term trends or detect VOC sources, but may be more expensive and cumbersome to use than other VOC testing kits [6].
Final Thought: There are various VOC testing kits on the market, such as passive sampling kits, active sampling kits, and continuous monitoring systems. Each kit comes with advantages and disadvantages and you should decide which kit to use depending on the VOCs being analyzed, the level of accuracy required, and your application.

Factors to consider when choosing a VOC testing kit
There are many things you should consider before buying a VOC testing kit: what VOCs you are testing for, how sensitive and accurate the kit is, and how easy to use. We will take these factors a little closer in this subtopic.
What kind of VOCs do you want to test for is another thing to consider when buying a VOC test kit. The different VOC testing kits cover a variety of VOC ranges and the best kit to use for the relevant VOC is also critical [1]. For instance, some kits can be used to identify a general set of VOCs and others are more specific and only work with a small set of VOCs [2].
There’s also the sensitivity and precision of the VOC test kit. The kit’s sensitivity tells you how sensitive it is to detect VOCs in the low-level range, while accuracy tells you how close the kit measurements are to the actual concentration of VOCs in the air [3]. Pick a kit that’s sensitive and accurate enough for your application, as well as any applicable regulations [4].
The convenience of the VOC testing kit is another thing. The more user friendly and easiest to operate kits tend to be better quality for users who don’t know much about VOC testing [5]. Ease of use can refer to things like how easy the kit is to build, if there are instructions and guides that are clear, or technical support or other sources [6].
So, in short, there are several things to take into account when choosing a VOC testing kit, like what VOCs you’re testing for, the sensitivity and accuracy of the kit, and the user friendliness. You can use all these things to select the best VOC test kit for your purpose.

How to use a VOC testing kit
An accurate and precise result from a VOC test kit requires proper application of a VOC test kit. We will dive into the specifics of this subtopic to show you how to use a VOC testing kit properly: setup, sample collection and analysis, interpretation of results.
VOC Testing Site Preparation Before the testing of VOC, make sure to prepare the test site. This may be done by having the area well ventilated, switching off any possible VOC sources, and leaving the area vacated for a sufficient amount of time [1]. – follow any specific preparation instructions issued by the VOC testing kit manufacturer [2] also.
: Once the test site has been prepared, the samples can be taken and analysed. What the actual sampling and analysis will look like depends on what VOC test kit you’re using, but generally you’ll use the kit to get a sample of the air and then you’ll analyze the sample with the kit’s analytical tools or sensors [3]. Important: Follow the manufacturer’s instructions exactly and take precautions to avoid contamination of the samples [4].
After collecting and analysing samples, the last thing you have to do is read the results. This can include comparison of measured VOCs to any corresponding regulatory criteria or standards, and any other relevant factors such as the health effects of VOCs present [5]. Retrospective analysis of the findings is warranted and considerations for sources of error or bias affecting the precision of the measurements [6].
To sum up, testing for VOCs in a manner that’s appropriate involves a process whereby setting up the test field, sampling and analysis of samples, and interpretation of the results. With good care, referring to manufacturer’s instructions and considering things like regulations and error-prone areas, you can get the correct and reliable results from VOC testing kit.

Interpreting VOC testing results
Accurately interpreting VOC testing results is an important step in understanding the quality of indoor air. In this subtopic, we will explore the various ways in which VOC testing results can be interpreted and what they can tell us about indoor air quality.
One way to interpret VOC testing results is by comparing the measured concentrations of VOCs to any relevant regulatory guidelines or standards. For example, in the United States, the Safe Drinking Water Act (SDWA) establishes maximum contaminant levels (MCLs) for certain VOCs in drinking water [1]. In the case of indoor air quality, there are also a variety of guidelines and standards that can be used to evaluate the presence of VOCs, such as those published by the World Health Organization (WHO) or the Environmental Protection Agency (EPA) [2]. By comparing the measured concentrations of VOCs to these guidelines or standards, it is possible to determine whether the levels of VOCs in the air are safe or potentially harmful.
Another way to interpret VOC testing results is by considering the potential health impacts of the VOCs present. Many VOCs can have negative effects on human health, including eye, nose, and throat irritation; headaches; dizziness; and nausea [3]. Long-term exposure to certain VOCs has also been linked to more serious health problems, such as cancer and neurological disorders [4]. By considering the potential health impacts of the VOCs present, it is possible to determine the potential risks of exposure and to take steps to improve indoor air quality as needed.
In conclusion, there are a variety of ways in which VOC testing results can be interpreted, including comparing the measured concentrations to regulatory guidelines or standards and considering the potential health impacts of the VOCs present. By carefully interpreting VOC testing results, it is possible to gain a better understanding of indoor air quality and to take appropriate steps to improve it as needed.
