We need OSHAs detection limit DL for the analysis of crystalline silica in order to apply it to the results we get from our private contract lab. Where can we obtain OSHAs DL?
As discussed above re. SAEs, contact your contract lab for the detection limit data they have determined for their analyses. The qualitative detection limit is usually defined as the amount of analyte equivalent to three times the standard deviation of the instrument response for low level spikes on sampling media using the slope of the calibration curve of low level calibration standards. The low level spikes may be made either at a single low level to obtain the standard deviation, or the standard error of estimate of the regression for several low level spikes bracketing the detection limit may be used instead of the standard deviation at a single level. Ten or more spiked samples are recommended depending on whether spikes are at a single or several levels. The quantitative detection limit is usually defined as 3.33 times the qualitative detection limit defined above.
