HENG MEI Intelligent Manufacturing Matching Food Safety Methods to Sample Matrices

A multifunction food safety workflow begins by matching each target to its assay and food matrix. HM-GS800 supports a broad test menu using different methods. The selected assay determines extraction, reaction conditions, controls and result interpretation for that particular test.

HM-GS800 is part of the HENG MEI Intelligent Manufacturing range supplied by Shandong Hengmei Electronic Technology Co., Ltd.

How the measurement works

HM-GS800 combines colorimetric and colloidal-gold test workflows in a portable platform. Each target uses its corresponding reagent or card, extraction process and reading program. The instrument menu becomes useful when those components are matched to the food matrix and the required decision.

Set up the analytical workflow

1. Select the target, sample matrix and compatible assay procedure.
2. Prepare the sample extract using the specified materials and quantities.
3. Process blanks or controls and observe the assay reaction and reading window.
4. Save the result with the method and reagent lot, then follow the agreed review procedure.

Technical configuration

Plan consumable quantities by assay

For 24 food samples tested for three targets, the starting workload is 72 sample-assay combinations. If the procedure requires separate reactions for every target, consumable demand follows those 72 reactions plus blanks, controls and repeats. When one extract can serve several tests under the approved methods, account for extraction savings separately from reaction consumption.

Make screening decisions traceable

A result should identify the food matrix, target, method and reagent lot. An enzyme-inhibition value addresses its screening chemistry, while a target-specific card follows its own interpretation rules. Set the follow-up process before the testing visit so an unexpected finding can be retained, reviewed and confirmed through the appropriate method.

Configure a mixed food-screening workload

A screening team visiting a market may handle vegetables, meat and aquatic products in one shift. Build separate preparation and reaction sequences for each selected assay instead of treating all foods as one matrix. Identify the tools that can be shared and those that require dedicated handling or cleaning. Schedule cards and color reactions so their reading windows remain manageable. Before leaving the site, reconcile sample IDs, controls and completed tests with the original work list. Preserve any unresolved result for the defined review process. The complete workflow links the portable analyzer to sample preparation, consumable supply and a clear reporting decision.

Compare complete target-and-matrix workflows

Prepare a purchasing list that pairs every target with the food to be tested. Specify the assay format, extraction equipment, control material and expected daily sample count for each pairing. This reveals whether the same operator can manage the reaction timing and whether extra preparation tools are needed. Evaluate the configured menu and consumable supply together.

Investigate unexpected results

Keep a usable analytical record

Retain these details with the result so the preparation, measurement and subsequent review can be reconstructed.

• Food lot and sample identity
• Target and assay program
• Extraction details and reagent lot
• Controls, result and follow-up action

Technical questions from operators

Is the number of listed tests enough to compare systems?

Compare the actual configured assay menu, matrices, consumables and preparation workflow.

Can one preparation serve every food test?

Extraction requirements vary by assay and matrix. Use the corresponding test procedure.

Use the required controls and the method settings for each sample group, and preserve the original observations alongside the accepted result and review action.
