Mass Spectrometry & Spectroscopy 9 New Analysis Tool Quickly Detects, Classifies and Identifies Microparticles


WITec GmbH, pioneer of Raman imaging and correlative microscopy, has introduced ParticleScout, a revolutionary particle analysis tool for the alpha300 Raman microscope series. It enables researchers to find, classify, quantify and identify particles quickly and easily.


ParticleScout delivers a greatly accelerated workflow to the researcher investigating particulate samples while making full use of confocal Raman imaging’s abilities in fast, label-free and nondestructive chemical characterisation. It begins by surveying samples with bright and dark field illumination to view the particles they contain. Image Stitching combines many measured areas for a detailed overview of large areas and Focus Stacking allows larger particles to be sharply rendered for accurate outline recognition. The optical images lead to the creation of a mask which is used to physically categorise particles of interest and arrange them in a ranked list. A Raman spectrum is then automatically acquired from each particle.


The Raman spectra are evaluated and the particles they correspond to can be identified manually or by using the seamlessly-integrated WITec TrueMatch Raman database software. This integration of a particle analysis tool with a Raman database is unique in the industry and offers a streamlined experimental environment to boost productivity.


Finally, ParticleScout generates a comprehensive report that features user-selectable combinations of filters and advanced algorithms to show the quantities of selected particles and their prevalence relative to other groups. These reports make ParticleScout the perfect tool for finding correlations between the physical and chemical attributes of particles.


From large-area imaging to high-resolution spectroscopy, the technology underlying ParticleScout provides thorough and detailed insight to the researcher in microplastics research, environmental science, pharmaceutical research, geology, food science and many other fields.


“ParticleScout expands our product range into an area that is currently experiencing an enormous boom due to the public debate on microplastics in the environment. Raman spectroscopy is an extremely powerful tool for the rapid identification of these sorts of harmful particles,” explained Dr Joachim Koenen, WITec Co-founder and Managing Director. “In addition, ParticleScout provides an unprecedented level of speed and ease of use in particle analysis with Raman microscopy. With ParticleScout, a time-consuming sequence of individual steps has been transformed into a flowing, continuous and fast process,” Koenen continued.

New Mini-Spectrometer Offering High Sensitivity Announced


Hamamatsu Photonics has recently developed their smallest grating spectrometer, the SMD series mini- spectrometer C14384MA, offering high near-infrared sensitivity, compact size, light weight and low cost. Compared to Hamamatsu’s existing range of MS series mini-spectrometers, the C14384MA is about 1/40th of the cubic size and 1/30th of the weight. It also offers sensitivity in the same near-infrared range, but around 50 times higher. This makes the C14384MA ideal for applications where real-time on-site measurement is required, for example quality inspection of food or agricultural crops and environmental analysis from quadcopters to drones.

Pellet Press Ideal for High-Quality Pellet Preparation Announced The manual, hydraulic Pellet


Press from Fritsch GmbH is ideal for the preparation of pellets with a smooth, homogeneous surface for spectral analyses such as X-ray fluorescence analysis or infrared spectroscopy for elementary analysis. It is suitable for the


manufacturing of both solid and highly permeable pellets of solid samples, fast and easy.


The pressure force is variable up


to maximum 250 kN and is automatically relieved in case of overstress. The clearly designed pressure force displays in 10 kN steps. Pressing tools for pellets with 12 mm, 32 mm, 15 mm and 40 mm diameter are available.


Operation is simple. Just fill in the sample, close the magnetically-held door and build-up the desired pressure using the hand lever. The compact yet robust instrument is easy to clean and comes with impact- resistant cladding.


For the comminution of the solid samples Fritsch recommend the Vibrating Cup Mill PULVERISETTE 9 which is ideal for extremely fast size-reduction of hard, brittle and fibrous materials down to analytical fineness.

SP014_LabTech19_Az180x125_E_RZ.indd 1 21.02.19 16:41 48632pr@reply-direct.com New NMR and EPR Explosion Protection Chamber Keeps Researchers Safe


Researchers performing pressurised NMR or EPR experiments face a danger of the tube breaking or fracturing while under pressure. The NMR & EPR Explosion Protection Chamber by Wilmad-LabGlass - SP Scienceware shields researchers from flying debris and brings a new level of safety to the laboratory.


High-pressure experiments have significantly grown in popularity over the last several years. As a result, the risk of tube explosion in the laboratory has also increased. The Explosion Protection Chamber solves this safety issue by preventing debris from projecting sideways towards the researcher should an explosion occur.


“For many years researchers have used blast shields to prepare high-pressure NMR & EPR samples, but this method leaves them exposed when transporting pressurised glass tubes to the spectrometer,” stated Susan Butch, Portfolio Manager for Wilmad-LabGlass. “Using this chamber, researchers can shield themselves throughout their entire experiment, from sample preparation, to transport, to loading.”


one-size-fits-all design allows for the chamber to be assembled in double barrel mode for Bruker spectrometers or single barrel mode for Varian / Agilent and Jeol spectrometers. modular leg array ensures that the product fits securely against the upper barrel protruding from the magnet.


The NMR & EPR Explosion Protection Chamber arrives with all accessories needed to begin using immediately.
