Introduction
Mycotoxins are naturally occurring toxic secondary metabolites produced by various species of fungi, particularly Aspergillus, Penicillium, Fusarium, Alternaria, and Claviceps. These toxins frequently contaminate cereals, grains, spices, nuts, coffee, cocoa, dairy products, animal feed, and processed foods. Even at very low concentrations, mycotoxins can pose significant risks to human and animal health, making reliable detection essential for food safety and regulatory compliance.
Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS) has become the preferred analytical technique for mycotoxin analysis because it offers exceptional sensitivity, high selectivity, simultaneous multi-mycotoxin detection, and accurate quantification in complex food matrices. Modern Chromatography Systems equipped with LC-MS/MS technology enable laboratories to perform high-throughput screening and confirmatory analysis for a broad spectrum of mycotoxins.
This article explains the principles of mycotoxin analysis by LC-MS/MS, sample preparation, analytical workflow, applications, maintenance, and key considerations when selecting a chromatography system.
What is Mycotoxin Analysis?
Mycotoxin analysis is the qualitative and quantitative determination of fungal toxins present in food products, agricultural commodities, animal feed, biological samples, and environmental materials.
The primary objectives include:
Food safety monitoring
Regulatory compliance
Export certification
Agricultural quality control
Animal feed testing
Risk assessment
Public health protection
Research and development
Accurate analysis helps protect consumers while supporting international food trade.
Why Use LC-MS/MS for Mycotoxin Analysis?
LC-MS/MS is considered the analytical technique of choice because it provides:
Ultra-low detection limits
Excellent selectivity
Simultaneous multi-mycotoxin analysis
High analytical accuracy
Excellent reproducibility
Rapid sample throughput
Reliable compound confirmation
Minimal matrix interference
These advantages make LC-MS/MS suitable for routine quality control and regulatory testing laboratories.
Common Mycotoxins Analyzed
Modern LC-MS/MS methods can simultaneously determine numerous mycotoxins.
Aflatoxins
Produced primarily by Aspergillus species.
Examples include:
Aflatoxin B1

Working Principle of LC-MS/MS
The analytical process involves two stages.
Liquid Chromatography
The chromatographic column separates individual mycotoxins according to their polarity and interaction with the stationary phase.
Tandem Mass Spectrometry
The mass spectrometer:
Ionizes separated compounds
Selects precursor ions
Produces characteristic product ions
Confirms compound identity
Quantifies analytes using calibration standards
Triple Quadrupole LC-MS/MS generally operates in Multiple Reaction Monitoring (MRM) mode, providing excellent sensitivity and selectivity for trace-level contaminants.
