HENG MEI Intelligent Manufacturing Automated Portable Raman Analysis for Food Screening

Automated portable Raman analysis combines a spectrometer, application software and the required sample method. HM-TLM1 uses Raman measurements with application-specific enhancement reagents and preparation for food screening. Automation supports the analytical sequence when the target and matrix are covered by the configured method.

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.

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.

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.

Put the selected method into practice

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.

Plan support for common operating issues

Plan the complete working configuration

Create a target-by-food-matrix menu and identify the required preparation materials and enhancement reagents. Assess who prepares samples, how controls are run and how spectra and reports are retained. Compare the actual configured methods and consumable costs. Treat automated analysis as one part of the workflow, with sample preparation and result review included.

Define the acceptance and reporting requirements

Agree on the following items when configuring HM-TLM1. They connect the equipment and consumables to the intended measurement and provide a basis for operator training and result review.

• Food matrix and target method
• Extraction and enhancement reagent lot
• Spectrum and software method version
• Controls and screening follow-up

Questions from buyers and laboratory teams

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.

For a HM-TLM1 configuration enquiry, provide the sample type, required measurements, expected workload and reporting requirements. Include the consumables, preparation equipment and support arrangements needed at the installation site.
