The analysis you’ve always desired for nano- to microscale separations.

The ACQUITY UPLC M-Class System delivers the most robust, reliable, and highest quality nano- to microscale UPLC separations to every laboratory performing LC/MS analyses. With unprecedented usability, the ACQUITY UPLC M-Class System enables laboratories to succeed in analyzing compounds that are severely limited in amount or availability, even amid a complex matrix over several orders of magnitude.

Confidently achieve your laboratory goals with high-efficiency ACQUITY UPLC M-Class Columns ranging from 75 µm to 1 mm I.D. by using complementary mass spectrometry to support our full range of column I.D.’s, or run 300 µm to 1 mm I.D. columns with optical detection.

The system also offers a range of flexible configurations for HDX technology, UV detection, and 2D analysis.

Your inlet to MS.

The ACQUITY UPLC M-Class System expands the performance of any nano- to microscale MS analysis. It increases the linear dynamic range of your analysis, resulting in better MS analyses by DDA or MS^E. The direct(non split) automatic solvent flow control algorithms of the ACQUITY UPLC M-Class System provide pulse-less flow for increased retention time reproducibility. Sample integrity is maintained due the ACQUITY UPLC M-Class System’s non-reactive surfaces. New drivers for MassLynx Software integrate the system seamlessly into your existing workflows.

Monitor protein conformation with HDX technology.

The ACQUITY UPLC M-Class System can quantify small changes in protein conformation by extending its pressure range to enable a higher efficiency separation. The system still integrates all the steps of HDX from sample prep to actual sequence determination, D₂ uptake curves, and comparison plots with Waters, interactive, highly innovative DynamX™ HDX Data Analysis Software.

HDX data has become an enabling technology that can be used to make business decisions about:

Drug candidate binding to a protein target
Biopharmaceutical product development
Protein-protein interactions
Intellectual Property

Expand the dynamic range of your analysis with 2D separations.

The ACQUITY UPLC M-Class System has streamlined 2D-LC separations with a highly intuitive menu-driven method setup, standardized separation chemistries, and intelligent valve operation. Expanding on the use of a novel 2D reversed phase/reversed phase (RP/RP) approach, where the 1^st dimension is run at pH 10 and the 2^nd at pH 2, grants the ability to robustly increase sample throughput with MS-compatible eluents.
