Significance of the topic

Clinical research laboratories face growing demands for rapid, sensitive and reliable assays to support drug development and diagnostic testing. Monitoring antiepileptic drugs in biological fluids is critical for therapeutic drug management, ensuring patient safety and optimizing dosage regimens. Compact, high-performance LC-MS/MS systems streamline workflows, improve data quality and maximize laboratory efficiency in space-constrained environments.

Objectives and overview of the study

This study evaluates the analytical performance of the Agilent Ultivo Triple Quadrupole LC/MS system for quantification of 15 antiepileptic compounds in biological matrices. The aim is to demonstrate high throughput, robust sensitivity and reproducibility alongside a minimized instrument footprint.

Methodology and instrumentation

The assay employs liquid chromatography-tandem mass spectrometry (LC-MS/MS) using the Agilent Ultivo system. Key hardware features include:

• Vortex Collision Cell for accelerated scan cycles.
• Cyclone Ion Guide to enhance ion transmission efficiency.
• VacShield technology for rapid, tool-free maintenance.
• Intelligent diagnostics for proactive troubleshooting and reduced downtime.

Sample preparation consisted of protein precipitation of biological fluids, chromatographic separation and multiple reaction monitoring (MRM) acquisition of target analytes.

Main results and discussion

• All 15 antiepileptic drugs yielded linear calibration curves, with accuracy within ±20% at the lowest concentration level.
• Intra-day precision showed coefficients of variation below 15% across calibration points, indicating excellent reproducibility.
• The compact Ultivo system occupies approximately 70% less bench space than comparable instruments, enabling higher throughput in limited laboratory real estate.
• Integrated diagnostics and simplified maintenance protocols minimized downtime and supported continuous operation.

Benefits and practical applications of the method

This approach offers several advantages for clinical research laboratories:
