82 New Affordable Raman Microscope for QA/QC Labs


Horiba Scientific announces the launch of its new XploRA ONE Raman microscope. XploRA ONE offers simplicity, exceptional sensitivity and reliability for budget-conscious QA/QC and analytical labs in the industrial and routine analytical sectors.


XploRA ONE offers ‘One-Shot’ full spectral analysis and programmable measurement templates for the Raman analysis and identification of samples. This translates to simple operation from acquisition to reporting.


XploRA ONE has a simplified and easy-to-use configuration and user interface, powered by new LabSpec 6 software suite. The intuitive interface enables a logical experiment workflow, from sample acquisition and visualisation, measurement set up, data interpretation and final reports. The end result is a Raman microscope designed to optimise productivity and efficiency at the push of a button, without compromising features or results.


XploRA ONE provides an affordable entry into full confocal Raman microscopy, with an option for our SWIFT technology which provides Raman imaging up to 10X faster. The system includes auto-calibration and validation software to ensure data accuracy with ‘one shot’ operation. Spectral databases are also included for simple interpretation of results. Laser options are integrated internally (532nm or 785nm CLS high brightness) for optimised sub micron-resolved measurements.


“XploRA One is ideally suited to routine and QC measurements of a host of applications, including polymers, pharmaceuticals, carbon nanotubes and coatings, graphene, semiconductors, geological and forensic samples,” said Andrew Whitley, VP of Sales for Horiba Scientific. “As both a high performing microscope and Raman micro-spectrometer, the price tag makes it an especially attractive instrument for QA/QC chemists and analytical scientists who previously were not able to access this attractive technique.”

Report on the use of AFM and the Tip Assisted Optics Module to Study Individual Nanotubes and Fibrils


JPK Instruments reports on the research studies of Dr Ioan Notingher, associate professor in the faculty of science at the University of Nottingham. With a research interest in the development of new optical and spectroscopic methods for studying biomaterials, he is applying JPK's atomic force microscope (AFM) system, the NanoWizard®


, and tip assisted optics module (TAO).


Dr Ioan Notingher is interested in the development of new optical and spectroscopic methods for studying biological materials at a nano and micro-scale. The main aim of his research is to understand the supramolecular architecture of self-assembled peptide and protein nanostructures. Understanding the interactions between the molecules is crucial for optimising the physical, chemical and biological properties of these unique materials for biomedical applications such as advanced drug delivery, tissue engineering or biosensing. At the same time, nanoscale investigations of the molecular properties of self-assembled peptide nanotubes will advance the understanding of intermolecular interactions which lead to neurogenerative diseases. Such fundamental understanding at the molecular level is required for developing new therapies and preventive strategies.


The addition of AFM and TAO from JPK allows Dr Notingher and his colleagues to focus their investigations on individual nanotubes or fibrils. This is very important because these nano materials have a high heterogeneity in terms of size and shape.


Therefore, techniques which require a large number of tubes cannot be used as they provide averaged results which cannot be extrapolated to individual nanotubes. Other techniques such as electron microscopy were limited to morphological studies. Complementary is the information brought by AFM and the optical spectroscopy techniques which allow more detailed investigations at a molecular level, such as studies of hydrogen bonding and molecular orientation.


Speaking of the benefits of the JPK NanoWizard AFM, Dr Notingher said "It allows us to integrate with optical spectroscopy. This means the size/shape and mechanical properties can be measured by AFM and vibrational spectroscopy can be performed on the same nano- or micro-tube. The TAO allows full control over AFM tip. For example, in the case of tip-enhanced Raman spectroscopy, the tip can be aligned accurately in the laser spot then the sample is scanned laterally to build images."
