This is not easy at all. Your source of CO2 if it is a bottle will have a pressure. Your bicarb should be dry to make sure you weight it properly. If you want to measure ratios of 100 above 100ppm the home made way is decent, but for atmospheric/domestic variations that's not going to cut it. Plus as the other commenter said, CO2 creeps into plastics and leach slowly after so you have to let your system equilibrate which then opens you at the effects of porosity and diffusion. |
