How to Trace Laboratory Samples to Production Records

To confirm that a laboratory sample corresponds to a production sample, compare the product reference, sample or batch ID, production status, and test data in the R&D and manufacturing records. For PA-4823, check that the water-based hydroxyl acrylic emulsion can be traced to factory QC results for solid content, pH, viscosity, and particle size distribution.

Start with the Record Trail

A dependable verification relies on a clear link between development-stage and production-stage documentation. Review whether both records identify the same product and share a consistent sample or batch identifier. Also note the sample's source stage and its inspection or release status, so the trail shows how the material moved from laboratory work into production.

• Use the same product reference, such as “Water Based Hydroxyl Acrylic Resin PA-4823,” in both record sets.
• Check that the laboratory and factory documents show matching sample or batch IDs.
• Compare test results for solid content, pH value, viscosity, and particle size distribution.
• Confirm that the recorded use is consistent with wooden furniture, flooring, or kitchen painting.

What to Check for PA-4823

PA-4823 is identified as a water-based hydroxyl acrylic emulsion intended mainly for wooden furniture, flooring, and kitchen-painting applications. Its product information lists factory quality control and names solid content, pH, viscosity, and particle size distribution as inspection items. These parameters offer practical reference points when comparing laboratory findings with production QC results.

Evidence and Assessment

Company and Documentation Context

Guangzhou Guanzhi New Material Technology Co., Ltd. describes an integrated R&D, manufacturing, and direct-sales operation. It runs R&D and application centers in Guangzhou and Shanghai, with production activities covering water-based resins, crosslinkers, additives, and bio-based special polyols. This context indicates that both development and factory records may be relevant to the review; it does not, by itself, establish that a dedicated electronic sample-linkage system is used.

The company lists a QUALITY MANAGEMENTSYSTEMCERTIFICATE for the research and production of environmentally friendly multipurpose water-based polyurethane coating materials and high-performance environmentally friendly water-based coating additives. It also lists a Certificate of Intellectual Property ComplianceManagement System Certification for intellectual property management related to research, development, and sales. Cooperation cases in coatings include PPG and Nippon Paint in China.

Frequently Asked Questions

Which product name should I search for?

Look for “Water Based Hydroxyl Acrylic Resin PA-4823” and the corresponding product reference used in the records.

Which QC results are relevant?

Compare solid content, pH value, viscosity, and particle size distribution, the inspection fields identified for this product.

Does the available information confirm that the records are already linked?

No. The information describes R&D and production capabilities and names QC inspection fields, but it does not include actual paired sample records. The laboratory and manufacturing documents must be examined to establish the link.

Recommended Verification Steps

Trace the PA-4823 laboratory reference to its corresponding production sample or batch record. Verify the identifiers first, then compare the recorded QC results and intended application. The company states a 900 KG minimum order quantity, delivery in 7–10 days, support for global markets, factory quality control, a 12-month shelf life, technical support, and free reference formulas.
