Accurate and precise measurement of the total and aromatic hydrogen content of gas oils and other fuel products can be performed using the Spinsolve benchtop NMR spectrometer.
This application note describes the FTIR method for the measurement and calculation of the -NH and -SiH content in silicon nitride films.
In the present work, a comparison between infrared spectroscopy (IR) and hydrogen forward scattering (HFS) results is presented. The hydrogen content
Raman Spectrometer Raman spectrometers are used to measure the Raman scattering of light from a sample. The design of a typical Raman
This article discusses how hydrogen content is determined in a variety of reference materials and petroleum fuel standards using the picoSpin 80

Abstract We revisit here how Raman spectroscopy can be used to estimate the H content in hard hydrogenated amorphous carbon layers. The H content was varied from 2 at.% to 30 at.%, using
6.6.1 Chemical Equivalent and Non-Equivalent Protons In the above 1 H NMR spectrum of methyl acetate (Fig. 6.6a), we can see that there are three signals.
Processes such as electroplating or acid cleaning are notorious causes of post-processing failure through hydrogen embrittlement. So, the determination of amounts of hydrogen in
A spectrometer is any instrument used to view and analyze a range (or a spectrum) of a given characteristic for a substance (e.g., a range of mass-to-charge values
Relative difference between the calculated H content by using FTIR absorption spectra and H effusion measurement. [...] Hydrogen effusion measurements have
Spectrometers use light wavelengths to investigate the chemical composition of a sample. Atomic spectrometers use an analytical method by which one or several

Fourier Transform Infrared (FTIR) Spectroscopy is a key tool for identifying chemical compounds and analyzing molecular structures. Learn how
FTIR spectroscopy, particularly the Lanford and Rand method, is a valuable tool for non-destructive, fast, and reliable analysis of hydrogen concentration in silicon nitride films.
Total and Aromatic Hydrogen Content Determination in Fuels Using Benchtop NMR Spectroscopy The total hydrogen content is a very important parameter for many petroleum products such as gasoline,
The following table lists infrared spectroscopy absorptions by frequency regions.
Description: This handout is designed to furnish you with a basic understanding of Nuclear Magnetic Resonance (NMR) Spectroscopy. The concepts implicit and fundamental to the operation of a
The ASTM method D7171 (ASTM D-7171 2011) covers the determination of the hydrogen content of middle distillate petroleum products using a low-resolution pulsed NMR spectrometer.
We revisit here how Raman spectroscopy can be used to estimate the H content in hard hydrogenated amorphous carbon layers. The H content was varied from 2 at.% to 30 at.%, using heat treatments of
For 20 years, Oxford Instruments led the way with the Oxford 4000 Continuous Wave (CW) NMR Analyser, an American Society for Testing and Materials (ASTM) compliant instrument, for rapid and
Introduction There has been a renewed interest in the research and development of silicon nitride (SiN x:H) films due to their excellent physical, mechanical, and optoelectronic properties. Silicon nitride
The lowest H contents measured with this technique are H/H+C ~ 20 at.%. We revisit here the H content determination of a-C:H layers by means of Raman microscopy. To this aim, we analyze the evolution
We present a comprehensive multiwavelength Raman investigation of a variety of hydrogenated amorphous carbons (π β C: H), ranging from polymeric π β C: H to diamond-like π β C: H

1H NMR spectroscopy is defined as a technique that utilizes the omnipresence and high natural abundance of 1H nuclei to identify and quantify metabolites in bio-fluids or tissue extracts, often
By default, gas chromatography (GC) is used to determine the calorific value. However, GC is comparatively expensive, quite slow and complex in general (e.g. carrier and calibra-tion gases are
