Spectroscopy
Spectroscopy is quick and non-destructive.
We specialise in combining spectroscopy with advanced chemometrics, making it a reliable way to verify the integrity of almost any commodity using a non-targeted approach.
Molecular fingerprints are identified using Near-Infrared (NIR) or Fourier Transform Infrared Spectroscopy (FTIR) which detect the unique chemical bonds within molecules by producing an infrared absorption spectral waveform.
What is Spectroscopy?
Spectroscopy is the measurement of the interaction of light with matter.
All matter interacts differently to light, therefore each spectrum produced is considered a unique “fingerprint”.
When light encounters matter, some wavelengths of light will be absorbed as the molecules vibrate. Spectroscopy is used to monitor reflected or transmitted wavelengths which are then recorded in the form of a spectrum.
Spectroscopy is used to detect, identify and quantify information about atoms and molecules. Because different materials interact with light in different ways, spectroscopy can be used to verify whether a sample is what the label claims to be.
Authenticity
Identification of authenticity in products such as herbs, spices, cocoa, oils and rice.
Time
Identification of molecule changes over time, to suggest age, maturity or expiration.
Waste
The ability to verify the wrong specification or formulation before it’s used.
Quality
Spectroscopy identifies the uniformity and consistency of materials across batches.
Safety
Inconsistencies are identified very quickly, increasing the speed of decision making.
Process
Spectroscopy is available where it’s needed, either in a lab or as a handheld device.
Traceability
Spectroscopy can be used in the determination of origin by detecting molecular variations.
Variety
Sensitive enough to identify different varieties of items such as rice or coffee.
