basic information
The inspection and analysis of unknown samples is generally referred to as qualitative testing. Qualitative testing can be divided into several patterns as follows: 1. Simultaneous qualitative analysis of elements dissolved in water → ICP/MS, GC/MS, IC, etc. 2. Qualitative analysis of foreign substances suspended or precipitated in water → After moisture removal, FT-IR or EPMA, etc. 3. Qualitative analysis of so-called solids that do not contain moisture → FT-IR or EPMA, etc. 4. Estimation of leakage → To be considered according to the condition of the sample. 5. Other simple qualitative tests, such as acid decomposition treatment tests, combustion tests, etc.
