Evaluation of Measurement<br />
Calculate 1,1,1-trichloroethane concentration:<br />
Y [mg/L] = A • B • (X [ppm] + C)<br />
Cross Sensitivity<br />
Perchloroethylene, carbon tetrachloride, dichloromethane and<br />
trichloroethylene are indicated with lower sensitivity. Petroleum<br />
hydrocarbons are not indicated.<br />
