Exploris 240 LC/GC-Orbitrap FT-MS

The Thermo Scientific™ Orbitrap Exploris™ 240 mass spectrometer provides the performance and versatility in a wide range of applications including small organic molecules, peptides, oligonucleotides and intact protein analyses. This instrument comes with the fast-scanning High-Field Orbitrap mass analyser, it is compatible with many next-generation ion sources but also the Triversa NanoMate® nanochip-based ESI as well as the FAIMS Pro™ interface.

Key points of this new FT-MS system are:

Ion sources:

  • The instrument is delivered with the OptaMax™ NG ion source including an adjustable heated electrospray ionization (H-ESI II) probe for ultimate sensitivity
  • The APCI and APPI probes can be easily installed for ionization of specific compound classes and interfacing with UPLC
  • The new SICRIT® Ionization Source (Plasmion) combining ESI, APCI and APPI can be installed very quickly and easily for direct injection or interfacing the GC to FT-MS
    .

    .
  • The instrument is equipped with the Triversa NanoMatefor nanoflow chip-based infusion experiments offering very smooth ESI ionization conditions crucial for sensitive compounds.
  • The Liquid Extraction Surface Analysis (LESA®) technology is available on the Triversa NanoMate, offering new techniques of HRMS surface analyses.
  • The online gas-phase fractionation system FAIMS Pro (high field asymmetric ion mobility spectrometry) has been purchased for this Exploris 240. Based on differential ion mobility, this device increases the analytical selectivity and adds an additional fractionation step prior to MS while reducing time-consuming sample preparation.
  • Polarity switching can be performed for any of the described Ion sources.

Orbitrap mass analyzer for FT-MS and MS/MS:

  • The segmented quadrupole mass filter allows precursor ion selection with variable precursor isolation width from 0.4 to 1,200 Da and a MS/MS precursor ion selection with high transmission from m/z 40 to 2,500. The quadrupole mass range is extended to m/z 8000 with the BioPharma option for protein and large biomolecule analysis. Up to 20 precursors per scan can be selected for fragmentation, for multiplexing
  • Reliable Automatic gain control (AGC) measurements for controlled injection of the number of ions is ensured by the novel Independent Charge Detector Orbitrap mass analyser
  • The High-Field Orbitrap mass analyser with low noise detection pre-amplifier and a 4kV central electrode voltage
  • The Exploris 240 delivers a resolution performance restricted to 240 k at m/z 200, which indeed might not be sufficient in some cases to resolve fine isotopic structures. To increase the resolving power of the instrument, the Booster® data acquisition system (Spectroswiss) is installed to the system. This device adds many advantages for example for the analysis of protein samples in particular for complex overlapping proteoform patterns, but also small molecule applications such as biofuel / biomass analysis.

Interchangeability of UPLC and GC for FT-MS coupling:

The extreme originality of our set-up is certainly the easy interchangeability between GC and UPLC separations prior to HRMS. This can be done thanks to the Sicrit® ionization source allowing direct coupling of GC to the Exploris 240 through a special heated transfer line (See Picture).

VION IMS QTOF


.
It delivers high resolution, high sensitivity, sub 1 ppm mass accuracy, and enhanced quantitative performance. Data acquisition methods use ion mobility as standard. Automatic data processing, data visualization and reporting are done using UNIFI®. Ion mobility cleans up and simplifies the spectra, enabling identification of all the compounds in the samples. With CCS values available for every ion in every analysis, new levels of confidence can be reached for identification. Identification based on CCS and <1 ppm mass accuracy is precise and independent of retention time.

Ion mobility:

Ion mobility separation not only allows chromatographically coeluting compounds to be resolved, but also structural isomers. Single component precursor/product ion spectra can be generated as ion mobility allows drift time and retention time alignment of product ion tp their respective precursors.

HDMSE fragmentation:

Every single analysis comes with data independent low and high energy collision induced dissociation, adding interesting structural information to accurate mass and CCS data.
