Abstract: As the sample of N 2H 4,MMH and UDMH mixture gas in air is collected by sampling tube for concentration MMH,the concentration of N 2H 4,MMH and UDMH is measured simultaneously by spectrophotometer.The experimental results show that the relative error of measurement is less than 17%,and recovery rate of every components is greater than 80% by comparison with the check of standard mixture gas.This method is suitable for detection of low concentration hydrazine fuel waste gas in air
