The LOQ, Limits of Quantification,are the fiber <br /> concentrations,for the given volume of the sampled air,above and below which the results may be unreliable. The RL,Reporting Limit defined in <br /> Method 7400 as LOD,is the fibers/cc below which the results may not be confidently distinguished from background levels.
