However, just the accurate mass is not enough for determining the definite molecular formula of natural products because of the combinatorial explosion. [3] It has been shown that even with 0.1 ppm.

X-ray crystallography (XRC) is a technique used for determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal.

2.1. Tandem mass spectrometry (MS/MS) The basic principle of MS/MS is the selection of precursor ion, fragmentation of this ion, usually by collision-induced dissociation (CID), and measurement of the m/z ratio of the product ions formed. There are two fundamentally different approaches to MS/MS: tandem in space and tandem in time.

The cell is constructed by higher-order structures and organelles through complex interactions among distinct structural constituents. The centrosome is a membraneless organelle composed of two.

INTRODUCTION Chemical ionization mass spectrometry (CIMS) has become a powerful ana- lytical technique in various disciplines such as medicinal chemistry, pharmacol- ogy, environmental studies, forensic.

Tandem mass spectrometry, also known as MS/MS or MS 2, involves multiple steps of mass spectrometry selection, with some form of fragmentation occurring in between the stages. In a tandem mass spectrometer, ions are formed in the ion source and separated by mass-to-charge ratio in the first stage of mass spectrometry (MS1). Ions of a particular mass-to-charge ratio (precursor ions) are.
