Norcada Inc si 3 n 4 chips
Limit of detection estimation at 8-BM using the capillary optic. We inspected histograms of low-mass concentration pixels from the Ca image of the kidney partial section of Fig. 1 ( c ) taken at per-pixel dwell time t dwell = 50 ms (thus, at an incident fluence of = 2.8 × 10 6 photons µm −2 – see Section 3 ) and of a photon statistics-corrected scan of an empty Si 3 N 4 under the assumption of no Ca presence (we increased the distribution width of the histogram of the Si 3 N 4 window scan by a factor of two for the statistics correction because we scanned it at t dwell = 200 ms). We empirically estimated a limit of detection ≃ 0.05 µg cm −2 for the kidney partial section since we did not observe that many ‘false-positive’ pixels in the empty Si 3 N 4 window scan. Our limit of detection was an estimate; a more rigorous statistical approach [see Currie (1968 ), for instance] would be needed for a more accurate determination of such a parameter. See Section 2.1 for more details about choosing to look at Ca for the kidney partial section.
