Basic steps of analysis
Thread Content
For general sample analysis, the basic steps of analysis are: sampling — sample preprocessing — analysis and measurement — data recording and processing — obtaining results, right? This post was last edited by zjs0536 on 2009-3-4 12:33.]
It’s basically like this: sample – preparation before sample analysis – analysis and measurement – results.
The process is as follows: sampling—preparing the analysis sample—sample pretreatment—analysis and measurement—analysis results. It should include an analysis of the sample preparation process. For unknown samples, when using wet analysis, qualitative analysis must be conducted before quantitative analysis.
Sampling, sample preparation, sample testing, result analysis
The original poster is basically correct. There are different opinions upstairs, but they all essentially mean the same thing. Personal opinion: For a specific object of analysis, there are specific methods. 1. Sampling, 2. Sample preparation (pre-treatment of samples), 3. Analysis and testing, 4. Data recording, 5. Providing analysis results and making judgments.
Supports the view from Floor 5: victory:
It’s not very complete: sampling, sample weighing, sample decomposition, selection of analysis methods, separation of interfering impurities, analysis and determination, and result calculation.
The original poster is basically correct. In my personal opinion, the analysis of a sample should involve: 1. Sampling, 2. Sample preparation (pre-treatment of the sample), 3. Analysis and testing, 4. Recording data, 5. Providing analysis results and making judgments. However, attention should be paid to the correctness of sampling during the process (solid samples are different from liquid or gas samples) ； The same applies to the sample preparation process; attention should be paid to various dry and wet methods, as well as other techniques such as screening and reduction
