Data acquisition for liquid chromatography

  • How a sample is separated and detected in liquid chromatography?

    A certain amount of sample is injected into the column and the compounds contained in the sample are separated.
    The compounds separated in the column are detected by a detector downstream of the column and each compound is identified and quantified..

  • What information can be obtained from a chromatogram?

    A chromatogram can provide a wealth of information about the chemistry of the intermolecular interactions between the analytes and the stationary phase and it provides the first step in evaluating separation performance and performing instrument troubleshooting..

  • What is chromatography data analysis?

    Chromatographic analysis of samples containing mixtures of sugars is an essential operation in any laboratory concerned with carbohydrates, whether sugars as such or carbohydrates of higher molar mass (polysaccharides or glycoconjugates and their depolymerization products)..

  • A sample matrix may be solid, particulate, or a mixture of organic compounds in an aqueous solution, and may consist of many components such as macromolecules and small molecules.
  • Chromatography works because the different components of the mixture will separate at different points as it passes through the stationary phase.
    This happens because the components have different levels of attraction to both the mobile and stationary phases, due to the polarity of the substances used.
  • Liquid chromatography (LC) is a chromatographic technique used to separate and analyze mixtures of chemical components in solution, to determine if a specific component is present or absent and, if present, how much of it is there.
Data acquisition requires that the output from the computer is scaled to a suitable voltage that will permit analog to digital (A/D) conversion.

Can metabolomic data acquisition combines DDA and Dia analyses?

In this work, we proposed a novel metabolomic data acquisition workflow that combines DDA and DIA analyses to achieve better metabolomic data quality, including:

  1. enhanced metabolome coverage
  2. tandem mass spectrometry (MS 2) coverage
  3. MS 2 quality

What are data dependent and data independent acquisition methods?

Mass spectrometry data dependent and data independent acquisition protocols are increasingly used in metabolomic and lipidomic experiments.
Data dependent acquisition methods have been improved by progress in HRMS analyzers and software tools helping to focus on relevant features.

Data-independent acquisition (DIA) for liquid chromatography tandem mass spectrometry (LC-MS/MS) can improve the depth and reproducibility of the acquired proteomics datasets.

Which data acquisition modes can be used in LC-MS-based metabolomics?

Existing data acquisition modes such as:

  1. full-scan
  2. data-dependent (DDA)
  3. data-independent acquisition (DIA) often present limited capabilities in capturing metabolic information in liquid chromatography-mass spectrometry (LC-MS)-based metabolomics
