Operating procedures for inspection of 1,2-hexanediol

The following are the operating procedures for 1,2-hexanediol testing: 1. Laboratory preparation: - Ensure the completeness of laboratory equipment and reagents. -Check if the instrument is working properly, such as gas chromatograph, pH meter, etc.
2. Sample preparation: - Prepare the test sample and record its relevant information, such as sample source, storage conditions, etc. -When necessary, perform pre-treatment on the sample, such as dilution, extraction, etc. -Please note that the storage and handling of samples should comply with safe operating procedures.
3. Preparation of reference material: - Prepare pure 1,2-hexanediol as a reference material. -The quality of pure products should comply with national standards or relevant regulations to ensure their purity and stability.
4. Instrument condition setting: - Set appropriate instrument conditions based on the characteristics of the sample to be tested, such as temperature program, flow rate, column type, etc. of the gas chromatograph.

It should be noted that the instrument conditions should be set in accordance with standard methods or analytical requirements.
5. Sample analysis: Inject the sample to be tested into the gas chromatograph and analyze it according to the conditions set by the instrument. -Record the analysis results, including peak area, peak height, retention time, etc.
6. Data processing: Calculate the content of 1,2-hexanediol in the sample based on standard curves or other quantitative methods. -Perform statistical analysis on the experimental results and record all data and the calculation process.
7. Result judgment: Compare the experimental results with relevant regulations, standards, or limit requirements. -Determine whether the content of 1,2-hexanediol in the sample meets the requirements and evaluate the quality of the sample.
8. Experimental safety: During the operation, follow the laboratory's safety operating regulations.

- Avoid contact with toxic, flammable or corrosive reagents, and wear personal protective equipment if necessary.
The above is the operating procedure for the inspection of 1,2-hexanediol. Before conducting experiments, it is necessary to carefully read relevant literature and methods to ensure the accuracy and reliability of the operation.
