Analyze complex mixtures faster than ever!

The Q Exactive HF mass spectrometer, with an ultra-high-field Thermo Scientific Orbitrap detector, provides new

levels of speed and resolution for every scan while maintaining high spectral quality for sensitive detection and

confident quantitation of peptides, lipids, metabolites, contaminants, and other important compound classes.

Quantify with the highest confidence.

With its unique spectrum-multiplexing capabilities and faster scan speed, the Q Exactive HF mass

spectrometer provides the speed necessary for precise quantitation even for narrow ultra-high-performance

liquid chromatography (UHPLC). Industry-leading high-resolution accurate mass (HR/AM) MS provides a more complete quantitative picture.

A digital data archive New levels of DIA capability

Targeted quantitative methods deliver the highest sensitivity, best precision, and lowest detection limits but require a priori

knowledge of the precursor ions (target molecules) and significant time and effort for SRM or PRM method development

and optimization.

In a true discovery quantitation environment, the targets may not be known and relative quantitation may be sufficient. In such

cases, data independent acquisition, is a viable quantitative approach. The Q Exactive HF MS enables several methods for DIA

data acquisition, including BASIC-DIA, pSMART-DIA, and MSx-DIA. These DIA methods fragment all ions present in the sample

to create a high-quality, permanent digital data archive of a sample that can be reanalyzed to look for new targets.

Superior intact protein characterization

The analysis of intact proteins presents a different set of challenges in which maximum resolution of the spectral features can help to distinguish major protein isoforms from lower abundant species. Particularly in biopharmaceutical applications, analyzing heterogeneous protein mixtures requires the highest

resolving capabilities combined with the high mass accuracy provided only with Orbitrap technology. The Q Exactive HF MS, with the optional Intact Protein Mode, enables high-resolution analysis of intact proteins, allowing detailed characterization of larger, more highly charged protein species such as intact antibodies and individual heavy and light chains. With the additional resolving power of the

Q Exactive HF MS proteins as large as 50 kDa can be isotopically resolved. This improved resolution allows routine, detailed characterization of proteins and biopharmaceuticals.

Increased productivity and confidence in lipidomics

The analysis of lipids poses a unique analytical challenge in research, as the closely related molecular structure of many lipid species produces multiple isobaric species within a relatively narrow mass range. This creates the risk of ambiguous lipid structure assignments. The high resolving power of the Q Exactive HF system greatly reduces this risk compared to instrumentation with lower resolving power. The Q Exactive HF MS is ideal for both infusion and LC-based workflow. Fast acquisition speed allows the system to keep pace with demanding lipid separations from complex samples.
