Summary
Hydrophilic interaction chromatography (HILIC) coupled with mass spectrometry offers powerful glycomics analysis. This technique efficiently separates glycans and glycopeptides, even resolving complex isobaric species with high sensitivity.
Area of Science:
- Analytical Chemistry
- Biochemistry
- Glycomics
Background:
- Structural glycomics is crucial for understanding biological processes.
- Glycans and glycopeptides require advanced separation techniques for analysis.
- Mass spectrometry provides sensitive detection for biomolecules.
Purpose of the Study:
- To highlight the utility of hydrophilic interaction chromatography (HILIC) for glycomics.
- To detail the separation mechanisms and applications of HILIC-MS.
- To compare online HILIC-MS with offline MALDI-MS(/MS) for glycan analysis.
Main Methods:
- Hydrophilic interaction chromatography (HILIC) utilizing hydrogen bonding, ionic, and dipole-dipole interactions for glycan retention.
- Online coupling of HILIC with nano-scale electrospray ionization-mass spectrometry (ESI-MS).
- Offline analysis of glycans using matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS(/MS)) in both negative and positive ion modes.
Main Results:
- HILIC-MS enables efficient separation of glycans, glycopeptides, and modified glycans, resolving isobaric species.
- Nano-scale HILIC-MS achieves a detection limit of approximately 1 femtomol for oligosaccharides.
- MALDI-MS(/MS) provides informative fragment ion spectra for deprotonated species (negative mode) and sodium adducts (positive mode).
Conclusions:
- HILIC coupled with mass spectrometry is a versatile and sensitive technique for comprehensive structural glycomics.
- Both online HILIC-MS and offline MALDI-MS(/MS) are valuable complementary methods for detailed glycan structural elucidation.
- The described methods facilitate high-resolution separation and sensitive detection of diverse glycan structures.

Mass Spectrometry: Complex Analysis
Mass spectrometry is an important technique for the identification of pure compounds. However, it has some limitations for the analysis of complex mixtures, often due to excessive fragmentation making the spectrum too complicated to decipher. Mass spectrometry can be combined with suitable separation methods in sequence, forming hyphenated methods, which are useful in the analysis of complex mixtures.

High-Resolution Mass Spectrometry (HRMS)
The resolution of a mass spectrometer depends on the efficiency of separating ions with different ion masses. The mass of an atom is approximated to the sum of the masses of protons and neutrons inside, considering the masses of protons and neutrons as equal. However, the masses of the proton (1.6726 × 10−24 g) and neutron (1.6749 × 10−24 g) are not truly equal. There is a minor error in the expression of atomic masses relative to the simplest atom of hydrogen. For example, the mass of helium...
