Abstract:
1. An inductively coupled plasma mass spectroscopy apparatus, comprising: a sample input configured to introduce a sample to be measured; an ionizer configured to ionize an element in the sample; an ion lens into which the ionized element is provided, wherein the ion lens is configured to focus the ionized element; a mass analyzer configured to segregate the ionized element; an ion measuring part configured to measure a signal intensity corresponding to a number of ions having a mass number segregated by the mass analyzer as a pulse count value and an analog current value; and an operation processor configured to determine a pulse-to-analog (P/A) coefficient for converting the analog current value into the pulse count value from the analog current value measured by the ion measuring part and the corresponding pulse count value, wherein the operation processor is configured to determine the P/A coefficient of the mass number from the analog current value and the pulse count value corresponding to the signal intensity of the mass number.
