  • Detection specification

Testing items such as boric acid content measurement. Scope of application Aquatic products, meat products (such as Rice-meat dumplings, fish balls), beans, pasta, Rolls of dried bean milk creams, brown seeds, cakes, soy sauce, etc. Relevant testing standards GB 5009.275-2016 National Food Safety Standard - Determination of Boric Acid in Food GB/T 21918-2008- Determination of Boric Acid in Food SN/T 4122-2015 Food Contact Materials Paper Determination of boric acid in recycled fiber materials DB22/T 1810-2013 Determination of boric acid and borate in food - Ion chromatography method SN/T 3041-2011 Determination of boric acid and sodium tetraborate in food contact materials for export - ICP-MS method - Ethylhexanediol trichloromethane extraction turmeric colorimetric method. The series of standard solutions were introduced into the instrument preparation system adjusted to the optimal conditions (see Appendix B) for determination. Draw a standard curve or calculate a regression equation using the concentration of boron as the horizontal axis and the intensity ratio of boron to internal standard elements as the vertical axis. Adjust the processed sample solution and reagent blank solution to the optimal conditions in the instrument atomization system for measurement. Compare the intensity ratio of boron element and internal standard element with the working curve or calculate the content using a surrogate equation. Precautions for testing reports: 1. The report is invalid without a "research and testing special seal" or an official seal, and the report is invalid without an anti-counterfeiting QR code; 2. The copied report is invalid without re stamping the "Research and Testing Special Seal" or official seal; 3. The report is invalid without the signature of the main inspector, reviewer, or approver; 4. The report is invalid if altered; 5. If there are any objections to the testing report, they should be raised within 15 days from the date of receiving the report, and overdue requests will not be accepted

Function of testing report:

1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report

2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms

3. Used as a sales report: issuing legally effective testing reports to make consumers more confident

4. Papers and research: Provide professional personalized testing needs

5. Judicial services: providing scientific, fair, and accurate testing data

6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problems

100% inspection and testing process:

1. Telephone communication and confirmation of requirements

2. Recommend solutions and confirm quotations

3. Mail samples and arrange testing

4. Progress tracking and result feedback

5. Provide reports and after-sales service

6. If urgent or priority processing is required

Testing and testing characteristics:
