The basic characteristics of inductively coupled plasma source mass spectrometry (ICP-MS) were investigated and operating parameters were optimized.
For the determination of trace elements in high-purity iron, a rapid and precise method was developed. After dissolution of a small amount of sample in a PFA test tube, 4-methyl-2-pentanone extraction technique was applied for the separation of the analytes from Fe matrix. Consumption of reagent was supressed and all procedure from dissolution to extraction was carried out in the same test tube to give a low blank value.
The use of the relationship between intensity and ionization potential enables a semiquantitative analysis without a calibration curve.
