| The sample with a surface area of 1 square meter was placed in the test chamber with a certain value of temperature, relative humidity, air velocity and air replacement rate.VOC is released from the sample and mixed with the air in the box. Periodically, the air in the box is extracted. The extracted air is absorbed through the adsorption tube.Calculate the amount of TVOC per cubic meter of air.The sampling is periodic until the TVOC concentration in the test chamber reaches equilibrium. | ||
