Understanding Liquid Chromatography Mass Spectrometry (LCMS)

Liquid chromatography and mass spectrometry are powerful techniques for analyzing complex mixtures, offering enhanced sensitivity and specificity in analysis. The term ‘sensitivity’ in LCMS refers to a change in signal per unit change in concentration of an analyte. It describes how the LCMS instrument can detect the relationship between the concentration of an analyte and the signal given. The field of LCMS has seen significant advancements, with advanced techniques improving the capabilities of LCMS, providing enhanced sensitivity and accuracy. Aral Research offers LCMS analysis in Ahmedabad with hands-on experience in working with clients from different fields.

The Science Behind LCMS: How Does LCMS Analysis Work?

Liquid Chromatography Components:

  • Mobile Phase: LC involves the physical separation of analytes in a sample of interest. A solvent carries the sample that is chosen based on the sample’s characteristics.
  • Stationary Phase: The substances in the column interact with components of the sample, helping the separation.
  • Flow Rates: The speed of the mobile phase travels via the column is important for controlling resolution time and resolution.

Mass Spectrometry Components:

  • Ion Souce: The ion source is vital for mass spectrometry for the ionization of molecules before they enter the mass analyzer. This process transforms the neutral molecules into ions to make them amenable to MS spectrometry.
  • Mass Analyzers: Different types of mass analyzers are available, providing different mass resolutions and accuracy capabilities. Quadrupole analyzers are used for routine analysis, while Time-of-Flight analyzers are used for high-resolution mass analysis.
  • Detectors: They convert physical signals from the ions into electrical signals, which are processed to give valuable data. They are vital for quantification and identification of analyzed compounds.

Working Principle Of LCMS

In liquid chromatography, the sample is dissolved in a solvent or mobile phase that passes through a column packed with a stationary phase. The sample components interact with the stationary phase for separation. It is crucial to note that factors like flow rates, solvent composition, and the properties of the stationary phase impact the process.

After separation by liquid chromatography, the compounds enter mass spectrometry to be ionized via methods like Atmospheric Pressure Chemical Ionization (APCI) and Electrospray Ionization (ESI). The ions are detected and sorted according to their mass-to-charge ratio (m/z) for the identification and quantification of compounds, offering a detailed view of the sample.

What is LCMS? How Does LCMS Work? 

What is Liquid Chromatography Mass Spectrometry? 

LCMS (full form is liquid chromatography mass spectrometry) is a combination of liquid chromatography (LC) and mass spectrometry (MS). It is an analytical method that employs chromatography separation of target compounds followed by mass-based detection. LCMS is used in biochemical research to test proteins and other molecules and in pharmaceutical development for research. Its ability to separate compounds based on molecular weight makes it indispensable in the analysis of larger molecules in the life science world. 

How Does LCMS Work? 

Liquid chromatography-mass spectrometry works in the following way: 

  • After the preparation, the samples are separated and concentrated in the LC instrument (high-performance liquid chromatography)
  • This passes through a column comprising of a stationary phase viz a silica or inert solid and a mobile phase viz a solvent. 
  • Different compounds pass through the column at different rates that effectively separate them. 
  • Every component reaches the end and enters the mass spectrometer chamber. In this section, every chemical species is ionized and accelerated by a flight chamber. 
  • The impact of the electric and magnetic field in the chamber separates the ions based on their masses and electrical charges. 
  • As they reach the end, a log of different molecular weights that have passed through the system is created.
