Campden BRI has invested in Fourier transform infra-red spectroscopy (FT-IR) from Agilent Technologies.
The technology has taken detection limits for results from the microgram to the nanogram range and from the parts per million (ppm) to the parts per billion (ppb) level.
The research institute has acquired an Agilent 670 FT-IR Spectrometer and 620 FTIR microscope, fitted with a Focal Plane Array Detector, said microscopist Mike Edwards.
“Individual spectra provide a ‘fingerprint’ of individual molecules, which can be used in the identification of incoming raw materials, determination of contamination, including deliberate adulteration (e.g. palm oil addition to virgin olive oil), and quality issues (such as sugar/acid ratio in tomatoes), as well as to identify the chemical composition of foreign bodies,” he said.
Campden BRI will be speaking at our Food Safety and Testing online event on September 26 which you can register for free.
