Benchtop NMR Spectrometer Used for Polymer Research at the Delft University of Technology


Magritek use of their Spinsolve Benchtop NMR spectrometer to study polymers at the Delft University of Technology. Dr Theo Dingemans is the Antoni van Leeuwenhoek Professor of Chemistry & Aerospace Engineering at the Delft University of Technology. His research in the Faculty of Aerospace Engineering focuses on the field of aerospace polymers to develop new polymeric materials which will ultimately lead to enabling technologies for the aerospace industry. His current emphasis is on tailoring and understanding the structure-property relationships of such new polymers. The research areas include liquid crystal network polymers, matrix resins for composites and ballistics applications. His all-aromatic ester-based nematic network polymers are of interest to the electronic and aerospace industry because these polymers exhibit a unique combination of thermal, physical and mechanical properties and excellent strength and elongation at break. When applied in carbon fibre based composites, these polymers perform better than current state-of-the-art high-performance polymers such as PEI or PEEK.


Dr Dingemans chose the Magritek Spinsolve system to use as a tool to check whether or not his group have synthesised the right molecule or not. In his lab, new polymers are designed and in order to do this, the team has to synthesise their own monomers. These are often aromatic/heterocyclic in nature so the spectrometer is very useful as it provides immediate information on the status of the chemistry. Once the pure compound is isolated, previously they would typically collect 1H and 13C high resolution spectra using a 500 MHz spectrometer located across the campus.


Talking about his work, Dr Dingemans said: “we use NMR to understand the structure/product confirmation of organic small molecules and polymers. Sometimes we use it to follow progress of the reactions. We chose the Spinsolve system because it’s very easy to use. It requires no cryogens and very little maintenance. When we need to use the high resolution NMR system, this requires sign-up and is on the other side of campus. Now we can do chemistry in the lab: take a sample and analyse it immediately. It improves our productivity in the lab.”

New Miniature Multispectral Photodiode Array Introduced


Pixelteq has released its PixelSensor™ 8-band multispectral photodiode array, packing eight wavelength-selective photodiodes into a compact 9mm square sensor. PixelSensor enables multispectral sensing at a smaller scale by integrating spectral filters at the sensor level, simplifying optical designs and reducing device integration costs.


The PixelSensor photodiode splits the visible spectrum into eight discrete colour bands. Its standard 20-pin LCC package can be surface or socket mounted. Common cathode operation provides low noise and fast response time. Customised OEM versions of PixelSensor are also available with user-defined spectral bands. Using Pixelteq’s exclusive micro-patterned optical filter technology, narrowband filters deliver improved sensitivity and contrast for multispectral applications from portable colour monitors to industrial and scientific instruments.


“Continuous 8-band sensing from a device that fits on your fingertip is a powerful tool for designers,” said Randel Mercer, VP Business Development of Pixelteq. “It’s exciting to see how our clients are implementing application-specific sensors that improve health, productivity, quality and safety across a wide range of devices.”


Pixelteq provides micro-patterned spectral filters, sensors, and cameras – helping users shrink multi-wavelength devices into a single package, enable new optical features and deliver application-specific sensors and cameras.
