Smallpdf is a Swiss online web-based PDF software, founded in 2013. [2] It offers free version with limited features to compress, convert and edit PDF documents. [ 3 ] And its paid version offers advanced features like OCR, compress, and more [ 4 ] .
This hexapole is inherently part of the Thermo lens system and is present in the ion path, regardless of the use of the collision cell. The collision/reaction gas mixtures can be 1% NH 3 in He, 7% H 2 in He and 100% H 2, where the NH 3 and H 2 are reactive gasses and the He is a collisional gas. The 3rd generation cell utilizes kinetic energy ...
Ion suppression in LC-MS and LC-MS/MS refers to reduced detector response, or signal:noise as a manifested effect of competition for ionisation efficiency in the ionisation source, between the analyte(s) of interest and other endogenous or exogenous (e.g. plasticisers extracted from plastic tubes, [1] mobile phase additives) species which have not been removed from the sample matrix during ...
A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+. The solvation number , n , determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table .
Ionic radius, r ion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice.
A schematic diagram of chemical ionization source. Chemical ionization (CI) is a soft ionization technique used in mass spectrometry. [1] [2] This was first introduced by Burnaby Munson and Frank H. Field in 1966. [3]
