The integral number of acetylene purity, the value is expressed in %, based on the scale value of the liquid level of the gas burette after absorption

Take the arithmetic average of the two parallel determination results of each bottle of gas as the determination result, and the difference in volume fraction of the two parallel determination results shall not exceed 0.
