The New GRAMS/AI™ Version 7 Thermo Galactic is proud to announce the release of GRAMS/AI version 7, the latest version of our renowned spectroscopy software. Compliance with 21 CFR Part 11, the FDA’s ruling on electronic signatures and records, has become a major issue for many analytical laboratories. Always the leader in desktop ...
Edible oils are not only a major source of nutrition but also a key basic material in the food industry. Vegetable oils are increasingly important because of their high content in mono- and polyunsaturated fatty acids in comparison with animal fats. In this application note, the main ingredients of olive oil, camellia oil, arachis oil, sunflower seed oil, and colza oil are analyzed using a ...

With the increasing demand for precision in livestock nutrition, accurate feed analysis has never been more essential. Near-infrared (NIR) spectroscopy has enhanced quality assessment, providing rapid, non-destructive analysis of key parameters such as moisture, protein, fat, and ash content. ...
Infrared Spectroscopy (IR) is a powerful experimental technique often used in the fields of analytical chemistry and biology, especially in the study of biomolecular structure and function. It offers detailed information about molecular vibrations, which are related to the formation, length, and type of specific chemical bonds in molecules.Infrared spectroscopy ...
Once near-infrared spectroscopy (NIRS, or NIR spectroscopy) has been successfully integrated in your analysis workflow, your lab will profit from a fast, accurate, and non-destructive method for routine analysis. But how should you proceed to implement NIR spectroscopy in your laboratory ...

Nuritas has recently published the results of two clinical studies on their next-generation ingredient PeptiStong™. Identified within fava beans, with self-affirmed GRAS and Health Canada approval, Peptistrong™ contains cell-signalling peptides which, when compared against milk proteins, were found to improve the rate of muscle protein synthesis during recovery. In this New Protein ...
April 23rd marks World Laboratory Day, a day to celebrate laboratories across the globe where scientists conduct valuable research and make new discoveries to improve our everyday lives. Although the origins of world Laboratory Day are still unclear, it gives us a chance to reflect on the great achievements and breakthroughs in scientific ...
For this reason, we have created a Glossary of some frequently used Spectroscopy Acronyms that you might find on our website or in the laboratory. Browse our frequently used spectroscopy acronyms: CCD: Charge-Coupled Device CNT: Carbon Nano Tubes CW: Continuous Wave EEM: Excitation-Emission Maps EPL: Picosecond Pulsed Diode Laser EPLED: Pulsed ...
In the first part of this series, a brief historical overview was given for both infrared (IR) and near-infrared (NIR) spectroscopy, as well as for Fourier transformation (FT) and dispersive spectroscopy. A few myths were discussed and put to rest, and we showed that Fourier transformation spectroscopy (FT-NIR) is not necessarily the only nor the best way to integrate reproducible spectroscopic ...

Spectroscopy is a precise and non-destructive technique that can tell us about several processes going on in plants and trees. ...
During normal NPP operation gaseous radioactive iodine measurements are collected on TEDA impregnated charcoal cartridges followed by gamma spectroscopy analysis in the radiochemistry laboratory. The collection of gaseous iodine species on the charcoal cartridge can be performed utilizing fixed station or portable air sampling systems. ...
This article focuses on the use of portable and handheld Raman spectroscopy in the field of forensic science and illustrates it with real-world examples. ...

Introduction: Traditionally, a geologist's analytical toolkit consisted of a hand lens, rock hammer, acid bottle, magnet, and perhaps a polarizing light microscope back in the laboratory. In geoscience professions, these tools are increasingly being supplemented by field and laboratory instrumentation that utilizes spectroscopy. ...

This paper reviews ongoing progress in the design and fabrication of new, on-chip, low loss planar molecular sensors. We report the details of device design, material selection and manufacturing processes used to realise high-index-contrast (HIC), compact micro-disk resonators. These structures have been fabricated in thermally evaporated As- and Ge-based chalcogenide glass films with PDMS ...
In both studies, the performance of the screening method was evaluated by comparing sample screening data with data generated from analysis of samples collected from the same location at the same time and analyzed in the laboratory using gas chromatography/mass spectroscopy (GC/MS). In both studies, an X-Wand® heated diode sensor device was used to perform the ...
Introduction: Spectral reflectance properties from. 0.45 to 4.3 μm have been investigated for a number of. mineral samples. Eight mineral samples were placed. in one of the environmental simulation chambers in the. University of Winnipeg’s spectroscopy lab [1,2]. The. eight samples and two standards spent 38 days in the. chamber. Of the eight samples (three silicates, two. carbonates and ...
The concentration of the gas species for those collected air samples can be subsequently analyzed with gas chromatography or mass-spectroscopy methods in a laboratory. The flux of the gas species can be estimated based on the rate of change of the gas species concentration inside the chamber and from information on other required variables, which can be obtained ...
