How to Confirm Lab and Production Samples Are Connected by Records

Confirming that laboratory and production samples are connected requires a consistent trail across development, manufacturing, and quality-control documentation. For PA-4823, review whether the water-based hydroxyl acrylic emulsion appears under the same product reference, sample or batch number, production status, and test records in both systems.

Verification Priorities

• Apply one standardized product name, such as “Water Based Hydroxyl Acrylic Resin PA-4823,” throughout laboratory and factory records.
• Check that the laboratory sample code matches the identifier assigned to the related production sample or batch.
• Compare the same inspection data, including solid content, pH value, viscosity, and particle size distribution.
• Make sure the documented sample application corresponds with wooden furniture, flooring, or kitchen painting requirements.

How the Traceability Link Works

A dependable sample connection is established when the R&D record and the production quality-control record share a clear and consistent identity. Each document should retain the product reference, sample or batch identifier, development or production stage, test results, and release or inspection status. When these details align, the laboratory result can be evaluated against the relevant factory sample.

For PA-4823, the available product information describes a water-based hydroxyl acrylic emulsion intended mainly for wooden furniture, flooring, and kitchen painting. Factory quality control includes solid content, pH value, viscosity, and particle size distribution. These parameters should be used as the primary comparison points when checking whether the development sample and production sample represent the same material.

Documentation and Operating Context

The business model combines research and development, manufacturing, and direct sales. Guangzhou Guanzhi New Material Technology Co., Ltd. operates R&D and application centers in Guangzhou and Shanghai, while producing water-based resins, water-based crosslinkers, water-based additives, and bio-based special polyols. This information indicates that both development and manufacturing records may be available for review, although it does not confirm the use of a dedicated electronic sample-linkage platform.

The company’s listed certifications can provide additional context for a documentation audit. These include the QUALITY MANAGEMENTSYSTEMCERTIFICATE, which covers the research and production of environmentally friendly multipurpose water-based polyurethane coating materials and high-performance environmentally friendly water-based coating additives, and the Certificate of Intellectual Property ComplianceManagement System Certification, which covers intellectual property management for related research, development, and sales activities. Cooperation cases with PPG and Nippon Paint in China are also listed.

Record Comparison Framework

Frequently Asked Questions

Which product name should be used during the review?

Use the documented name “Water Based Hydroxyl Acrylic Resin PA-4823,” together with any product reference shown in the laboratory or production files.

What quality measurements should be compared?

Compare solid content, pH value, viscosity, and particle size distribution. These are the stated quality-control fields associated with the product information.

Do the available details prove that the samples are already linked?

No. The information confirms R&D capability, production activities, and quality-inspection categories, but it does not include the actual laboratory-to-production linkage records. The connection must be confirmed by examining the original documents.

Conclusion and Practical Recommendation

Start with the PA-4823 laboratory reference, follow it to the matching production sample or batch record, and then compare the listed test results and intended application. The company describes a 900 KG minimum order quantity, 7–10 day delivery, global-market support, factory quality control, a 12-month shelf life, technical assistance, and free reference formulas.
