Shimadzu Liquid Chromatograph Mass Spectrometer LCMS-8050

Significance of the Topic

Liquid chromatography–tandem mass spectrometry (LC-MS/MS) is an indispensable tool in fields such as pharmaceutical development, environmental analysis and toxicology.
Rapid, high-sensitivity quantitation of trace compounds drives decisions in research, quality control and regulatory compliance.

Objectives and Study Overview

This document introduces the Shimadzu LCMS-8050 triple quadrupole system, showcasing its patented UF technologies to push the limits of speed and sensitivity.
It emphasizes simultaneous qualitative and quantitative workflows, high-throughput capabilities, and robust performance for complex matrices.

Methodology and Instrumentation

The LCMS-8050 integrates multiple UF technologies:

• UFsensitivity: Heated ESI probe and UFsweeper III collision cell for enhanced desolvation and sensitivity.
• UFswitching: 5 ms positive/negative polarity switching via high-voltage power supply.
• UFscanning: High-speed MS/MS scanning at 30,000 u/sec with 0.1 u steps for accurate mass spectra.
• UF-MRM: 555 MRM transitions/sec for large-panel quantitative analysis.

Paired with Nexera UHPLC and LabSolutions software for streamlined method development and data review.

Main Results and Discussion

Key performance highlights include:

• Reduction of CYP inhibition assay from 7 min to 1 min with over 20 data points per UHPLC peak and RSD <5 %.
• Concurrent MS/MS and MRM acquisition of 12 benzodiazepines at 1 ng/mL with precise quantitation and spectral integrity.
• Trace-level quantitation of 29 pesticides at 5–50 pg/mL without pre-concentration, meeting 1/100 regulatory targets.
• Attogram-level reproducibility for verapamil (500 ag) in plasma with 2.77 % RSD.
• 1,000-sample stability test in plasma showing 4.59 % RSD over successive injections.

Benefits and Practical Applications

These advances enable faster sample throughput, broader target panels in single runs, improved dynamic range, and reduced method development time.
The system’s robustness and ease of maintenance minimize downtime in routine and regulatory laboratories.
