A reengineered mass spectrometer prototype can now analyze up to a billion molecules simultaneously, a leap from conventional instruments that handle only a few at a time. The advance, reported in ...

Mass spectrometry is already a powerful tool for determining what kind and how many molecules are present in a given sample. But most instruments still analyze their molecules one or just a few at a ...

Researchers at Rockefeller University in the US have developed a prototype called MultiQ-IT, a ...

Mass spectrometry is a powerful analytical method used to identify and characterize molecules. People often mistakenly think that the data outputted by the technique come in the form of a mass ...

Its true value depends not on the number of detected features but on the reliability of metabolite identification and pathway analysis. Despite well-established guidelines, annotation and definitive ...

Mass spectrometry measures the mass-to-charge ratio of ions by ionizing chemical compounds to produce charged molecules. A typical mass spectrometer consists of three parts: a detector, a mass ...

How much does a molecule weigh? Well, that depends. Molecules, like people, come in various shapes and sizes. That difference in size can mean a lot for researchers in the ever-evolving pharmaceutical ...

The use of atmospheric plasmas is growing in interest due to their benefit in processing materials, mainly organic, which are unsuitable for high vacuum. Such discharges are generally studied by ...

One of the main objectives and problems in the discovery of new secondary metabolites is the identification of an exact molecular formula for natural products. [1] Molecular formulas can be employed ...
