NIST LIBRARY APPLICATIONS: More of What’s Being Analyzed?

nist-library-applications
In this post, we continue to follow applications of the NIST Library from a wide variety of situations and studies. So you can stay up-to-date on the activity scientists are reporting, here are some more recent studies using the NIST Mass Spectral Library that we think are interesting.

Food and Flavor Analysis

This study, recently presented in the International Journal of Dairy Technology, looks at the sensory quality of unheated and heated mozzarella-style cheeses with different fat, salt and calcium levels. Compounds were identified using mass spectra comparisons to the (slightly out of date) NIST 2011 Mass Spectral Library.

Finding Chemical Indicators of Early Childbirth Labor

A metabolite profile of cervicovaginal fluids from early pregnancy was found not to be predictive of spontaneous preterm birth. The study, published in the International Journal of Molecular Sciences, used an in-house mass spectral library and the (even more out of date) NIST 05 library to identify compounds.

Evaluating Oil Shale Extraction

Petroleum research studying the effect of temperature on the characteristics of retorting products obtained by oil shale pyrolysis was recently reported. The study made use of the NIST Library and GC-MS analysis to identify gases released at various temperatures. The results demonstrate that, as the gas production rate increases, char gradually reduces with an increasing temperature and remains unchanged above 850 °C.

Evaluating the Effects of Anesthetics

Reported in the Journal of Neuroscience Methods, researchers examined a method for continuous, stable perfusion of tissue and single cell preparations with various concentrations of volatile anesthetics. The study used NIST Mass Spectral Library comparisons to identify and confirm analyte peaks.

NIST LIBRARY APPLICATIONS: What’s Being Analyzed?

nist-library-analyzedNew spectra are being added to the NIST Library on a continuous basis and the library is used across a wide variety of situations and studies. Stay up-to-date on the activity scientists are reporting. Here are some recent studies using the NIST Mass Spectral Library that we think are interesting.

Fundamental Biodiesel Research

Evolutionary engineering was used to develop crude glycerol tolerant Rhizopus oryzae. This resulted in the activation of the glycerol metabolic pathway to strengthen the fumaric acid biosynthesis from crude glycerol.

Assessing Shelf Life of Fruit

The relationships between fruit composition and storage life in air or controlled atmosphere of the red raspberry were studied to examine physiological breakdown (PB) among various varieties. The NIST 08 Mass Spectral Library was utilized to determine tentative identification.

Wastewater Treatment Research

Maillard reaction products like melanoidins are recalcitrant, high-molecular-weight compounds responsible for the color in sugarcane molasses distillery wastewater. In this study, laccase was covalently immobilized on alumina pellets activated with aminopropyltriethoxysilane (APTES). The degradation compounds were identified using the NIST Mass Spectral Library.

Marine Organism Metabolism and Health

Anthopleura elegantissima, the most abundant intertidal sea anemone in the Pacific, was studied to determine the effect of Symbiotic State on the Fatty Acid Composition. Fatty acid methyl esters (FAMEs) were identified via mass spectrometry by comparing their retention times with a Supelco 37 Component FAME Mix (Sigma-Aldrich) and verified with the NIST Mass Spectral Library.
