Fluorine is critical for biomedicine. This element can help drug compounds be more potent and last longer in the body, and its radioactive isotope, fluorine-18, powers medical imaging techniques such ...

A new draft standard, ISO/DIS 18841, is under development by members of the International Organization for Standardization (ISO) to replace ISO 18841:2018, the existing general standard for ...

ABSTRACT: In this article, we propose developing a reliable and sensitive method for determining tryptamine (TRYP) levels in canned fish samples using spectrofluorimetric analysis. The analytical ...

Matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) is a promising tool for the spatial quantitation of endogenous and exogenous compounds directly in biological tissue ...

In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects interpretation of beta ...

Assets like equipment, vehicles and furniture lose value as they age. Parts wear out and pieces break, eventually requiring repair or replacement. Depreciation helps companies account for the ...

When scaling an established analytical method across columns packed with different particle sizes and different column configurations (internal diameters and lengths), the amount of time that is ...

Abstract: There are differences between the analytical results and the experimental results of the input total harmonic distortion (THD) of aviation multipulse rectifiers due to the power factor angle ...

This study analyzed formaldehyde content in three aqueous fragrances with results ranging from 7 to 85 μg mL-1. The high sample throughput of SIFT-MS ensures that the calibration curves for each ...

Abstract: The probability analysis method of theoretical line loss (TLL) is an emerging TLL assessment method in recent years, which can consider the impact of random changes in load, power source, ...
