ATR3000FD Raman Food Safety Analyser
Portable SERS-Raman screening for application-specific trace residues, additives and food contaminants
Description
The ATR3000FD is a specialised portable Raman analyser designed for food-safety screening methods that use Raman spectroscopy together with surface-enhanced Raman scattering (SERS). SERS substrates or reagents can increase Raman signal dramatically for selected molecules, allowing application-specific trace analysis that conventional direct Raman may not achieve. The instrument combines a cooled Raman system, touchscreen computer, camera and dedicated analytical workflows for targeted food contaminants, residues and additives.
Product Overview
Ordinary Raman spectroscopy works very well for many concentrated materials but is not inherently a trace-analysis technique for every molecule.
SERS changes this by placing target molecules close to nanostructured metallic surfaces that amplify the Raman electromagnetic field.
For the right target and validated preparation procedure, this can reduce detection limits substantially.
ATR3000FD combines the Raman hardware with application-specific SERS workflows, automated spectrum recognition and a portable case-based interface.
How SERS Measurement Works
A typical SERS method involves:
- sampling the food or extract
- preparing or extracting the target compound
- mixing or depositing the sample onto a SERS reagent/substrate
- acquiring the Raman spectrum
- processing characteristic SERS peaks
- comparing the result against a calibration or identification model
Because extraction efficiency and substrate behaviour matter, method validation is essential.

Applications
Depending on the validated SERS method, applications may include screening for selected:
- pesticide residues
- veterinary-drug residues
- illegal additives
- adulterants
- food contaminants
- pharmaceutical or health-product compounds
- research trace-analysis methods
The manufacturer describes ppb-level capability for selected developed methods. This must not be interpreted as a universal ppb detection limit.
Compatibility and Selection Guidance
The most important purchasing question is not simply the spectrometer specification; it is whether a validated SERS method exists for the desired analyte and sample matrix.
Before ordering, confirm:
- target analytes
- food/sample matrix
- extraction method
- SERS reagent
- calibration range
- required detection limit
- qualitative versus quantitative result
- consumable/reagent requirements

Frequently Asked Questions
What is SERS?
Surface-enhanced Raman scattering uses nanostructured metallic surfaces or particles to amplify Raman signals from molecules close to the surface.
Does ATR3000FD detect every pesticide?
No. Detection is method and analyte specific.
Is ppb sensitivity guaranteed?
No. Detection limit depends on analyte, matrix, preparation, SERS substrate and calibration.
Does food need sample preparation?
Many trace SERS methods require extraction or preparation even though conventional Raman itself may require little preparation.
Can the instrument perform normal Raman measurements?
The hardware is Raman-based, but ATR3000FD is specifically configured around food-safety/SERS workflows.
Are SERS reagents reusable?
This depends on the specific reagent/substrate; many SERS assays use consumable substrates or reagents.
