RapID and Vaya Portable
Raman Spectrometers
Through-container raw material verification
The portable RapID and the handheld Vaya instruments use Spatially Offset
Raman Spectroscopy (SORS) technology to identify solid and liquid materials
inside their containers. They are designed for high-throughput identification
testing of incoming raw materials. They work through opaque packaging,
such as paper sacks, FIBC, thick plastic containers, and amber glass bottles,
with a single 5 to 30 second measurement. Both instruments can verify the
identity of most active APIs, and common excipients and be used in a cGMP
warehouse for ID at receipt. They can replace existing Raman, NIR and FTIR
spectroscopy instruments being used for this purpose.
Identifying materials through the packaging allows you to:
– Avoid sampling booth, sampling booth costs, and quarantine delays
– Reduce QC lab turnaround times and expensive outsourced testing
– Maintain sterility, prevent cross-contamination
– Preserve shelf life of unopened products
– Avoid worker exposure to high potency APIs

The overlaid spectra of lactose monohydrate inside a Meggle sack and inside a polyethylene
liner show good agreement. By producing a spectrum of the raw material, free of container
interferences, the Agilent Vaya instrument can easily verify the identity of a raw material
through multilayer paper bags. Study: Rapid Identification of Raw Materials Inside Packaging
The Vaya and RapID instruments can measure
the Raman spectra of solid and liquid materials
without opening containers.
The overlaid Raman spectra of L-Alanine,
L-Phenylalanine, and Glycine amino acids.
These three amino acids can easily be
distinguished by their specific spectral markers.
