HENG MEI Intelligent Manufacturing Raman Food Screening from Extraction to Report

A food Raman screening workflow can include extraction, enhancement chemistry, spectral acquisition and software interpretation. HM-TLM1 integrates Raman hardware and analysis software in a portable case. Assess the complete assay sequence when planning field work.

HM-TLM1 is part of the HENG MEI Intelligent Manufacturing range supplied by Shandong Hengmei Electronic Technology Co., Ltd.

How the measurement works

HM-TLM1 integrates portable Raman acquisition and application software for configured food-screening methods. Enhancement reagents and sample preparation provide the assay-specific chemistry. Target coverage and performance depend on the complete method for the food matrix.

Set up the analytical workflow

1. Select the configured target method and prepare the sample extract.
2. Process enhancement reagents and controls according to that application procedure.
3. Acquire the Raman spectrum and run the corresponding software analysis.
4. Review control performance and spectral quality, then retain the method and reagent information with the report.

Technical configuration

Schedule the whole assay sequence

For a workflow requiring 15 minutes of preparation and reaction followed by one minute of acquisition and review, the sequential time is 16 minutes per sample. Batch preparation can change the schedule when the method permits parallel handling. Use the actual assay stages and reaction windows to estimate throughput for the intended menu.

Connect software interpretation to the prepared sample

Keep the target method, food matrix and enhancement reagent lot with the spectrum. Evaluate controls and signal quality before accepting an automatically generated conclusion. For a screening finding that triggers follow-up, retain sufficient material and the preparation record to support the next analytical step.

Manage a food Raman screening batch

Group samples by the configured target method and prepare the required controls with the batch. Track extraction quantities, enhancement reagent handling and reaction timing through to spectral acquisition. Arrange the sequence so operators can complete each reading within the assay conditions. Retain the original spectrum and the software result together. When screening identifies a sample for follow-up, keep its identity and preparation details linked to the retained material. This turns automated spectral analysis into an organized food-testing workflow with a clear path from sample receipt to the next analytical decision.

Configure automation around each target assay

List target-and-food combinations and the preparation needed for each. Determine which stages the software controls and which require operator handling. Plan enhancement reagent storage, controls and timing with the expected sample workload. Review spectra and reports with representative food samples when introducing a new application.

Investigate unexpected results

Keep a usable analytical record

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

Technical questions from operators

Does automated analysis remove manual preparation?

The food testing workflow includes enhancement reagents and sample preparation where required.

Can one detection limit be applied to the full menu?

Performance depends on the target, matrix and validated application 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.
