LCMS-2050 Single Quadrupole LC/MS - Features

Single Quadrupole Mass Spectrometer

Seamless integration with LC by design eliminates the installation and training costs of introducing an MS to the Laboratory

Compact for LC Systems

Designed to be the same width as the Shimadzu Nexera series LC components, the compact LCMS-2050 is stackable; no additional bench space is required. It can be integrated seamlessly with the Nexera series, i-Series, legacy model HPLC systems, and the Nexera Prep preparative system.



Easy Parameter Settings for Simplified Operation

Mass spectrometers are often considered difficult to use, but the advanced engineering of the LCMS-2050 makes it as simple to use as other LC detectors. Only the most basic of acquisition parameters are required to obtain reliable and sensitive detection.

Mass-it: Adds Mass Information to UV Chromatograms

Mass-it is a new function that annotates MS results onto LC results. Mass spectral information is automatically extracted from peaks and displayed on the UV chromatogram, enabling the user to verify MS and UV data simultaneously. Mass information on the UV chromatogram can alert the user to components with no UV absorption or co-eluting peaks, preventing compounds from being overlooked. Time savings and higher data integrity are the result.

A Highly Versatile Mass Spectrometer

Measures a Wide Range of Compounds

A heated dual ion source (DUIS), which combines the features of electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI), is the LCMS-2050’s standard ionization source, enabling compounds with a wide range of characteristics to be analyzed simultaneously. Heated DUIS includes both an ESI spray nozzle and an APCI corona needle, making it possible to detect both high and low polarity molecules in a single run. In the example below, high-polarity Simetryn is detected, as well as the low-polarity Quintozene, which is difficult to detect by ESI alone.

Biopolymer Analysis

With an m/z range of 2 to 2,000, the LCMS-2050 is capable of analyzing large biopolymers. Multiple charge states are produced by electrospray ionization of biomolecules, such as peptides, proteins, and oligonucleotides, making the LCMS-2050 suitable for the characterization of these compounds. A mass spectrum of Nusinersen, an antisense oligonucleotide with a molecular weight of 7127 u, is shown below. Five different multi-charged states were detected by the wide mass range of the LCMS-2050, enabling accurate deconvolution using LabSolutions Multi-charged ion analysis software. The molecular weight was determined with excellent accuracy.

High-Speed MS Suitable for UHPLC

High-speed MS data sampling is required for high-speed analysis by UHPLC. High-speed performance is a hallmark of Shimadzu LCMS detectors, and the LCMS-2050 is no exception. The LCMS-2050 provides the world’s fastest performance, with a scan speed of 15,000 u/sec and a positive/negative ion switching speed of 10 msec. Thanks to the sufficient sampling rate, the instrument reliably captures sharp UHPLC peaks. At slower scan speeds (7,500 and 10,000 u/sec), data points are insufficient, so the peaks are either lost (peak 2) or insufficiently separated (peaks 3 and 4, and peaks 5 and 6). If the scan speed is fast (15,000 u/sec), sufficient data points are ensured, so the peaks are sharp and their separation is good.

Space Savings - The LCMS-2050 is similar in size and stackable with LC units so it can be added without the need for additional space

Automatic Checks of Instrument Performance

Mass spectrometer calibration and calibration checks for mass accuracy, resolution, and intensity can be performed automatically using the System Check function. The calibration standard is injected through an independent ESI spray source, and re-calibration can be automatically initiated if required, resulting in consistent data acquisition and laboratory operation without the need of user intervention. Calibration report outputs ensure traceability of instrument status.

Comparison of Power Consumption

Comparison of Power Consumption

Thanks to its small size, its single-phase 100 to 240 V specifications, and its Ecology Mode function, the LCMS-2050 achieves energy savings of 43% in comparison to the LCMS-2020. It is also recognized as an Eco Product Plus under Shimadzu's proprietary environmentally friendly product recognition system. The system not only limits running costs during analysis, but contributes to a carbon-free society by limiting CO2 emissions.

Easy Maintenance


Like all other MS products by Shimadzu, the ionization interface of the LCMS-2050 has a simple, accessible design that minimizes the effort needed to maintain the instrument. The desolvation line (DL) that transfers the sample into the vacuum chamber can be replaced without using tools and without breaking vacuum. Quick and easy maintenance means less downtime, labor, and cost.
