LCMS-8050 - Features

High Sensitivity for Trace Quantitative Analysis

■Heated ESI Probe

In order to improve desolvation efficiency, the newly developed heated ESI probe combines a high-temperature gas with the nebulizer spray, assisting in the desolvation of large droplets and facilitating ionization. This development allows for high-sensitivity analysis of a wide range of target compounds.

■Excellent Reproducibility Even at Attogram (ag) Levels

Polarity Switching Technology with No Compromise in Quality or Sensitivity

■High-Sensitivity & High-Speed Positive/Negative Ionization Switching in 5 msec

Just One Minute per Analysis
A Case Study Using High-Speed Positive/Negative Ionization Switching

When performing simultaneous positive/negative ion measurements of multiple components, the proper acquisition of sharp UHPLC peaks depends on rapid polarity switching. The LCMS-8050 minimizes losses due to polarity switching and ensures the collection of sufficient data points for even the narrow peaks obtained with UHPLC, recording accurate peak shapes and allowing excellent reproducibility.

■Only 5 msec to Achieve Stable Quantitative Accuracy with Positive/Negative Ionization Switching

Comparison of measurement using the ultra-fast polarity switching (5msec) and individual measurement of positive and negative ions.

The LCMS-8050 uses unique high-voltage power supply technology to achieve an ultra-high-speed positive/negative ionization switching time of just 5 msec. The LCMS-8050 is also the only instrument of its type to maintain ion intensity even when performing polarity switching at ultra-high speed, yielding consistent, reproducible data. Excellent quantitative results can be obtained from UHPLC peaks no more than 2-3 seconds wide, even when multiple components are eluted simultaneously.

■Outstanding Throughput and Quantitative Accuracy

Simultaneous, Highly Reliable Quantitative and Qualitative Analysis

■High-Sensitivity & High-Speed Scanning at 30,000 u/sec

Simultaneous Quantitative and Qualitative Analysis Simultaneous High-Speed Screening of 12 Toxicological Drugs

The LCMS-8050 is capable of simultaneously obtaining both qualitative and quantitative information in a single analysis. Acquisition occurs so rapidly that MS/MS scans and MRM measurements can be performed concurrently while maintaining quantitative accuracy. MS/MS scans are usable and reliable because even at 30,000 u/sec, Shimadzu uses a 0.1 u scan step.

■Maintain Sensitivity and Mass Accuracy Even at 30,000 u/sec

By controlling the voltage applied to the quadrupoles according to scan speed and m/z, the LCMS-8050 achieves superior ion transmission at any scan speed. And because Shimadzu maintains data collection at 0.1 u intervals, high-quality mass spectra are obtained without loss of sensitivity or mass accuracy.

■Efficient Qualitative Analysis Using Synchronized Survey Scan

The Synchronized Survey Scan (SSS) function allows MRM acquisition to be combined with a variety of other scan modes. It is extremely useful for obtaining more detailed qualitative information on components detected during multi-analyte quantitative acquisition.

■ High-Sensitivity & High-Speed MRM at 555 ch/sec

Detect Target Compounds at Trace-Level Concentrations Simultaneous Analysis of 29 Pesticides for Water Quality Analysis

The LCMS-8050 is capable of simultaneously acquiring 555 MRM transitions per second while maintaining accuracy and precision. Sufficient data points can be collected for quantitation ions, reference ions, and internal standard ions even in chromatographic regions with unresolved peaks. The high sensitivity of the LCMS-8050 allows for trace-level analysis, such as pesticides in drinking water, without the need for sample pre-concentration. This high sensitivity is maintained even when monitoring numerous MRM channels.

■Maintains High Sensitivity Even During Successive Demanding Analyses

In addition to speed and sensitivity, Shimadzu designed the LCMS-8050 for robustness to meet the most demanding laboratory requirements and most difficult matrices. The figure below plots the area results from 1000 consecutive analyses of a deproteinized blood plasma sample spiked with alprazolam. The LCMS-8050 achieves excellent reproducibility with a 4.59 % RSD for the area results over the 1000 analyses.

■Easy System Maintenance Reduces Downtime

As with Shimadzu’s other triple quad systems, maintaining the LCMS-8050 is simple. Replacing the desolvation line (DL) and ESI capillary is quick and easy. Additionally, the design allows users to replace the DL without breaking vacuum, providing greater uptime and usability.
