If the samples were not collected by NVL Laboratories,then <br /> the accuracy of the results is limited by the methodology and acuity of the sample collector. 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.
