Another Hiccup

At this point I have acquired all of my materials. I have begun taking samples for the baseline level of formaldehyde for future comparison against levels with plants present. As you can see in the picture below the baseline level in my test room is only 10 ppb, (at least I know my home has relatively low formaldehyde levels), but this does not give me much room for experimentation because my detection limit is 5ppb. To address the issue I will be applying plastic resin glue made from urea formaldehyde to raise the formaldehyde levels. Ideally the test room will reach levels around 80-100 ppb.
