The performance of a new mass spectrometer is being evaluated for the analysis of uranium in well water. Replicate measurements of a blank provided a mean and standard deviation of 0.104 mV and 0.040 mV, respectively. The slope of the linear regression line was 2.78 (mV/nM). What are the signal limit of detection and the concentration detection limit, respectively (to 2 s.f. each)?
