We are currently working on a project regarding the heat treatment of low-quality gemstones. We need to fill different gas mixtures into the tube furnace. Therefore we seek a method to mix two non-reactive gases to specific ratios.
In our laboratory we use the MAP Mix 9001 device from Dansensor company to mix 2 or 3 gases at different percentages. Generally, CO2, N2 and O2 are the most common used gases in MAP (modified atmosphere packaging) technique.
