Spectral accuracy of molecular ions in an LTQ/Orbitrap mass spectrometer and implications for elemental composition determination
Abstract In addition to mass accuracy, the ability of a mass spectrometer to faithfully measure the isotopic distribution of an ion, defined as spectral accuracy, is also important. Although time-of-flight mass spectrometers are reported to possess high spectral accuracy capability compared with other mass spectrometers, the Orbitrap has not yet been investigated. Ten natural products ...

Construction of a low–cost laser–based multiplexed spectrometer: a potential probe for environmental pollution monitoring
A low–cost, sensitive, laser–based (Helium Neon; He–Ne) optical Fourier–transformed (multiplexed) spectrometer has been constructed for the quantification of suspended particulates in the air. The optomechanical features of the spectrometer are presented together with a theoretical framework of its operation. The apparatus is calibrated by using a standard commercial spectrophotometer and has ...

Optimized Photoluminescence Quantum Yield in Upconversion Composites considering the Scattering, Inner Filter Effects, Thickness, Self Absorption, and Temperature
Introduction Optimising upconversion (UC) composites is challenging as numerous effects influence their unique emission mechanism. Low scattering mediums increase the number of dopants excited, however, high scattering mediums increase the UC efficiency due to its non-linear power dependency. Scattering also leads to greater thermal effects and emission saturation at lower excitation power ...

Emission Correction in a Fluorescence Spectrometer
When fluorescence spectra are measured in Edinburgh Instruments fluorescence spectrometers, two types of correction can be applied to the spectra; excitation and emission correction. In this blog post we focus on the role of emission correction and discuss why it is required, how it is implemented, and the effect it has on the shape of fluorescence spectra.Why is Emission Correction Required?The ...

Growing hydrogen expectations: embedded catalyst design for active and stable catalysts
Hydrogen as an energy vector in combination with fuel cells is one of the emerging energy solution in terms of sustainability and low environmental impact. H2 sustainable production is therefore one of the key target of today. Recently, the Materials, Environment and Energy research group at the University of Trieste, coordinated by Professor Paolo Fornasiero investigated various options for H2 ...

Inside the Gas Analyser – the Spectrometer
The measurement principle of several types of OPSIS gas analysers is called DOAS, which stands for differential optical absorption spectroscopy. A key component of the analyser is the “spectrometer”, a unit which separates incoming light into its individual wavelengths for subsequent recording of the light spectrum. But how does a spectrometer work?The key is an optical component called a ...

Detection of Low Levels of Organic Species in Seawater
In this particular experiment, the sensitivity of a Hiden Quadrupole Mass Spectrometer (QMS) to dimethylsulphide was measured Dimethylsulphide (DMS) - chemical formula CH3SCH3- is a naturally produced trace substance, evolved from certain marine micro organisms, such as plankton. Detection of fluctuations in the DMS concentration in seawater therefore gives important information about the ...

Spinsolve - Ethyl Crotonate - Case Study
1H Spectra Ethyl crotonate (C6H10O2) is a colourless liquid at room temperature typically used as a solvent for cellulose esters as well as a plasticizer for acrylic resins. Figure 1 shows the 1H NMR spectrum of 250 mM Ethyl crotonate in CDCl3 measured in a single scan taking 15 seconds to acquire. The high resolution of the Spinsolve spectrometer can be particularly well appreciated in the ...

Applications of neural networks for free unfolding of experimental data from fusion neutron spectrometers
Free unfolding in neutron spectroscopy means reconstructing energy spectra from experimental data without a priori assumptions regarding their shape. Due to the ill-conditioned nature of the problem, this cannot be done analytically. Neural Networks (NNs) were applied to this task and synthetic data was used for training and testing. Results showed very consistent performance especially in the ...

On demand production of ethers or alcohols from furfural and HMF by selecting the composition of a Zr/Si catalyst
Acid catalysts have been the backbone of the chemical industry since the very first plants in which they were called to convert oil into precious products. With the progressive shift towards sustainable resources, often the old catalysts fail since biomass-based compounds feature different functional groups, each requiring a dedicated catalytic functionality to be effectively converted into the ...
