Agilent Triple Quadrupole GC/MS - Application Compendium

Significance of Topic

The triple quadrupole gas chromatography–mass spectrometry (GC/MS/MS) platform is a cornerstone in modern analytical chemistry, offering unmatched sensitivity and selectivity for trace-level analysis. Its applications span environmental monitoring, food safety, pharmaceutical quality control, and emerging fields like cannabis testing, making it a vital tool for regulatory compliance and research.

Study Objectives and Overview

This compendium presents a series of application notes for the Agilent 7000D and 7010B triple quadrupole GC/MS systems. It covers key workflows including automated MRM method development for US EPA Method 8270, pesticide residue quantitation in strawberries, fast screening protocols for semivolatiles, optimized PAH analysis in tough matrices, multiresidue pesticide methods in salmon, nitrosamine impurity determination in drugs, ultratrace dioxin and furan analysis, and challenging pesticide testing in cannabis and hemp.

Methodology and Instrumentation

Multiple advanced configurations and techniques are employed to maximize performance:

• GC systems: Agilent 8890, 7890B, Intuvo 9000
• Triple quadrupole MS: Agilent 7000D, 7010B with high efficiency EI or hydrogen source cleaning (JetClean)
• MRM Optimizer tool and dynamic MRM for automated transition selection
• Retention time locking, pulsed splitless injection, midcolumn backflush
• Sample preparation: Captiva EMR–Lipid cleanup for fatty matrices and optimized extraction for environmental samples

Main Results and Discussion

Key performance metrics demonstrate the platform’s versatility:

• Low limits of detection and quantitation (attogram to low microgram per kilogram levels)
• High linearity across wide dynamic ranges (R2 >0.99)
• Reproducible calibration stability with compound RSDs <10%
• Automated MRM development reduced method setup time and manual review
• Fast chromatographic runs (10–12 minutes) without sacrificing resolution
• Robust performance in complex matrices including soils, high lipid foods, and cannabis extracts

Practical Benefits and Applications

The Agilent GC/TQ solutions enable laboratories to:

• Streamline method development and validation for regulatory methods
• Increase sample throughput and reduce solvent and maintenance costs
