MASS SPECTROMETRY AND ITS PRINCIPLE


MASS SPECTROMETRY AND ITS PRINCIPLE


Mass spectrometry is an analytical technique used to quantify material or identify unknown materials. the process involves the conversion of samples into a gaseous form which are then differentiated by their mass to charge ratio (m/ z). ions are separated on the availability and abundance in the mass spectrum. The mass spectrum shows the plot of ion abundance versus charge–to–mass ratio. Ion gives the information of the structure and nature of the prime molecule of the sample.

The basic premise of mass spectrometry (MS) is to create ions from inorganic or organic substances using any acceptable method, separate them using their mass-to-charge ratio (m/z), and detect them qualitatively and quantitatively using their m/z and abundance. Thermally, by electric fields, or by striking energetic electrons, ions, or photons, the analyte can be ionized. Single ionized atoms, clusters, molecules, or their fragments or partners can all be considered ions. Static or dynamic electric or magnetic fields influence ion separation.

Despite the fact that this definition of mass spectrometry dated from 1968 (Kienitz, 1968), it is still relevant. Ion separation by m/z can also be achieved in field-free locations, as long as the ions have well-defined kinetic energy at the flight path's entrance.

For MS to work, atoms or molecules must have an electric charge, which means they must be converted into ions. The electric charge works as a handle, allowing these atoms or molecules to be grabbed. Ions, unlike neutrals, can be accelerated and decelerated, sent into predetermined orbits or other flight paths, and then collected and detected.

MASS SPECTROSCOPY CONGRESS 2021 organizing team invites various international researchers, professors, various science delegates from different fields to attend the 9th INTERNATIONAL CONFERENCE ON MASS SPECTROSCOPY AND CHROMATOGRAPHY “which is scheduled on October 29-30,2021 in ZURICH, SWITZERLAND.

This conference could be a stage for participation, sharing, and exploring the new areas of research and work done on mass spectroscopy and chromatography. The conference will upgrade our knowledge in understanding the current and future research perspectives.

Unlocking Smoother HPLC Method Transfer

Image
High-performance liquid chromatography (HPLC) is one of the mainstay techniques in an analytical chemistry lab. However, a key challenge in highly regulated laboratories is when scientists must switch from one HPLC system to another, or exchange methods between different labs and sites. The process of transferring a method to the receiving HPLC system involves checking and adjusting multiple parameters such as instrument settings and configurations. If this is not carried out carefully, the receiving instrument and method might produce results inconsistent with the original system in terms of retention times and peak shapes for the analytes of interest, ultimately rendering analysis unreliable. Conversely, making method adjustments can lead to lack of compliance with regulator validated analytical protocols. In this article, we review the main challenges with method transfer and highlight how advanced HPLC technologies can help smooth this transition.   The growing need for me...
