Derived mean count rate

WebJan 1, 2024 · Derived mean count rate as a function of sample temperature for a 1 mg/ml dispersion of BSA, recorded for a capillary sealed with clay. The onset of fluctuations in the detected scattering demonstrates the breakdown of the clay compound, most notably after 40 °C. During this experiment, the intended end temperature was 70 °C. WebNov 21, 2013 · Lochamy [4] derived count rate detection limits starting from Eq. (7), assuming that the uncertainty of the net count rate varied with the blank-count time. Derivation of a detection limit based on the blank count time different from the sample count time fails for the same reason that count time allocation fails.
