The relationship between the heating rate shown in Fig. 2 suggests that if you heat the sample faster, the total ion yield (the number of ions divided by the number of atoms in the loaded sample), shown by the area under the curve, is lower than in the case of slow heating of a similar load. So in the case of faster heating you improve the signal to noise ratio, but worsen counting statistics. How do you deal with this dilemma?
Thank you for your question. Comparing the reproducibility of measurements with the heating rate of 18, 90 and 450 mA/min, the best reproducibility was obtained with the heating rate of 450 mA/min for the measurement using 100 pg of Pb. For the reproducibility of measurements among this range of heating rates, it would suggest that the effect of the improvement of the signal to noise ratio by increasing peak intensity is greater than that of worsen counting statistics by decrease of the area under the curve.
