Spectroscopic platform

Description

The food spectroscopic platform includes a wide range of advanced instruments, such as Fourier Transform Infrared (FT-IR), Near-Infrared (NIR), Raman, Ultraviolet-Visible (UV-Vis), and Low-Field Nuclear Magnetic Resonance (NMR) spectrometers. These instruments allow for detailed analysis and characterization of food and related samples, supporting both qualitative and quantitative studies across various applications.

FT-IR VERTEX 70 with MultiRAM FT-Raman Module

The FT-IR VERTEX 70 is a Fourier Transform Infrared (FT-IR) spectrometer designed for accurate measurements in the range of 4000–30 cm⁻¹ with a high resolution of 0.5 cm⁻¹. It is a versatile instrument capable of analyzing a wide variety of food samples, including solids, liquids, and semi-liquids, making it ideal for applications in food science and technology.

It offers multiple measurement options, including:

  • Transmission mode
  • Attenuated Total Reflection (ATR) using the single-reflection diamond accessory Bruker Platinum, ideal for quick and non-destructive analysis.
  • Measurements samples in gas phase

The Multi-RAM module is a Raman spectrometer based on Fourier Transform technology. It features an Nd:YAG laser (1064 nm) and two advanced detectors: a high-sensitivity germanium detector and an InGaAs detector for extended spectral range capabilities. A computer-controlled sample stage allows for easy sample positioning. This module enables measurements in the spectral range of 3600–50 cm⁻¹ with a resolution of 0.5 cm⁻¹, ensuring precise and reliable results.

MQR-Spectra P LF-NMR

The MQR is a high-performance TD-NMR system designed for applications based on relaxation and/or diffusion measurements. The system includes a high-performance digital spectrometer, a 20 MHz (0.47T) permanent magnet, and 18 mm probes. It offers measurements in the temperature range of -20°C to 150°C.

It provides multiple measurement options, including:

  • FID and CPMG
  • Solid fat content (SFC%)
  • Droplet size distribution (DSD)
  • Diffusion measurements
  • Solid echo
  • 2D measurements
  • Kinetics

  • The sample amount depends on the sample type and the spectroscopic technique used.
  • Measurements are recorded by a superuser of the spectroscopic platform.
  • Independent operation is possible, but training is required.
  • Interpretation and analysis of results are not included in the fee.

 

 

When initiating a research collaboration with the University of Copenhagen, a cooperation agreement must be established. Different types of agreements are available depending on the nature of the collaboration. For more information, visit: collaboration.ku.dk/cooperation-agreements
