    Comparable number of protein IDs in half the time Base peak chromatogram (BPC) of a 120 min gradient on the Q Exactive Plus MS (red) and a 60 min gradient on the Q Exactive HF MS (blue) showing one half the analysis time.

    Improved productivity with Q Exactive HF MS

    The Q Exactive HF MS system completes 1 full MS scan at 60,000 resolution and 20 HCD MS/MS scans at 15,000

    resolution in 1.13 sec, 37% shorter compared to the Q Exactive Plus MS.

    Faster protein identification The highest quality protein identification from

    complex biological samples over the widest

    dynamic range is an absolute requirement for

    all proteomics labs. The Q Exactive HF system

    delivers the mass accuracy and resolution you

    expect combined with far greater speed than

    ever before, enabling protein identification that

    is faster and deeper than ever, while maintaining

    the resolution and accuracy required for

    confidence in your results. Under the same

    LC gradient conditions, the Q Exactive HF MS

    identifies approximately 30% more unique

    peptides and 20% more protein groups than the

    Q Exactive Plus MS system. The speed of the

    system enables gradient runs that are twice as

    fast (steeper gradients) while maintaining the

    ability to identify roughly the same number of

    unique peptides and protein groups.

    The faster scan speed of the Q Exactive HF

    MS results in higher number of precursor

    ions triggered for MS/MS—synonymous

    with improved productivity.

    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.

    Improved chromatographic sampling Extracted ion chromatograms (XIC) of the same peptide showing (A) only 4 points across the chromatographic peaks, and (B) 8 points across the peak. The short cycle time on the Q Exactive HF system samples the peak more frequently, ensuring the best quality quantitation.

    Improved quantitation linearity and reproducibility with PRM As a result of the improved selectivity, better quantitation over a large linear dynamic range is obtained. This demonstrates great reproducibility for very low amounts of target peptide in a complex background, in this example, 200 ng HeLa digest. The 2 amu isolation window clearly shows higher variability at the 0.01 fmol level vs. the narrower isolation width of 0.7 amu.

    Parallel Reaction Monitoring – the new paradigm for high-throughput targeted quantitation The high resolution accurate mass (HR/AM) capability of Orbitrap MS enables a new mode of quantitation – Parallel Reaction Monitoring (PRM).

    PRM relies on HR/AM to provide exquisite selectivity, high sensitivity, accurate and high throughput quantitation of analyte targets, and excellent

    MS/MS data to confirm target identification.

    Achieving quantitative precision The best precision in quantitation is achieved with the highest possible

    ion transmission and rapid data collection to correctly define analytical

    peak shape. The ultra-high-field Orbitrap analyzer of the Q Exactive HF

    system scans fast enough to accurately define narrow UHPLC peaks

    for optimal quantitative results.

    Enabling quantitative accuracy Quantitative accuracy is achieved by removing interferences from

    co-eluting analytes. The unique Advanced Active Beam Guide

    technology offers the ability to narrow the quadrupole isolation

    width to as little as 0.4 amu, significantly reducing the possibility

    of signal interference that can decrease selectivity and accuracy.

    For low level peptide quantitation by PRM, the extreme sensitivity

    of the Q Exactive HF system enables routine quantitation down

    to 0.01 fmole and provides extremely high precision using 0.7 amu

    isolation —as demonstrated by the very low coefficients of variation

    (CV) at the lowest levels of quantitation.

    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 you

    with a more complete quantitative picture.

    Comparison of replicate DIA quantitation results While replicate 4 exhibits a good correlation to the spectral library (0.97), replicate 3 is only moderately correlated (0.73). However, data can be confirmed at the MS1 level with 0.4 ppm mass error and with isotopic dot products greater than 0.9. If one replicate is questionable the excellent mass accuracy of the MS1 peak can be used to match the peptide and “save or recover” a poor replicate, so quantitation is performed on the MS1 precursor.

    Orbitrap-based HR/AM reduces false positives The Q Exactive HF MS provides high resolution and practical, experimental mass

    accuracies of less than 3 ppm for both precursor and fragment ions enabling very

    narrow mass windows to be used for data extraction and comparison to library

    spectra, greatly reducing the risk of false positive identifications using the

    BASIC-DIA method, relative to standard SWATH™ methods.

    High quality data to address complex samples The high resolution capability of the Q Exactive HF MS is a key

    attribute in separating legitimate signal from potential interferences.

    With resolutions up to 240,000 FWHM @ 200 m/z and low-ppm MS

    and MS/MS mass accuracy, the Q Exactive HF MS system provides

    superior selectivity to resolve isobaric fragments—significantly better

    than Q-ToF systems with their lower resolution, and limited accuracies.

    Selectivity through mass accuracy Comparison of selectivity obtained with 50 ppm mass accuracy (typical of ToF systems) vs. 5 ppm mass accuracy in MS/MS analyses, and the selectivity it brings to DIA analyses-only obtainable on Orbitrap-based systems.

    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.

  • 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, the analysis of 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, as well as the 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.

    The analysis of lipids poses a unique analytical challenge

    in research, as the closely related molecular structure of

    many lipid species produce 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

    workflows. Fast acquisition speed allows the system to keep

    pace with demanding lipid separations from complex samples.

    Increased productivity and confidence for lipidomics

    Identification of more lipid species at varying concentrations While the LC gradient for the Q Exactive HF system was 33% shorter (steeper LC gradient), the speed and resolution of the system still allowed identification of 20% more lipid species from a bovine heart lipid extract. LC method, column and gradients for the Q Exactive Plus MS and for the Q Exactive HF MS were identical.

    Increased resolution improves identification/quantitation The effect of resolving power for the identification of lipid species is illustrated for two Lyso phospholipid species, 18:1 LPE (lysophosphoethanolamine) and 16:0p LPC (lysophosphocholine). Identification of minor lipid species is challenging without sufficient mass resolution, leading to fewer identifications. In order to baseline-separate these two lipid species, a minimum of 60,000 resolving power (or higher) is required, easily achievable using high resolution Orbitrap technology.
