Access sub-ppm mass accuracy for at least five days with the Thermo Scientific EASY-IC ion source. With automated internal calibrant delivery, the EASY-IC ion source saves you time so you can quickly return to running your samples. Use the Thermo Scientific Pierce FlexMix calibration solution to perform a single calibration for the full mass range of m/z 40–3000, in both positive and negative modes.

Orbitrap Exploris 120 easy LC internal calibration

Through the use of Thermo Scientific EASY-IC ion source, sub-ppm mass accuracy is consistently delivered without user-intervention for at least five days. A panel of veterinary drugs with m/z range from 160…900 was analyzed at 100 µg/L over a 15-day period with continual polarity switching, providing exceptional mass accuracy.

The Orbitrap Exploris 120 mass spectrometer has demonstrated its ability to consistently deliver desired results on multiple instruments.

Orbitrap system consistency

To assess LC-HRAM MS system-to-system reproducibility, two operators at two different locations analyzed the same sample of veterinary drug residues in bovine muscle matrix on two separate systems. The minimal 5.1% average difference observed in analyte concentrations demonstrates high reproducibility across both Orbitrap Exploris 120 mass spectrometer systems.

Long term system robustness demonstrated for pesticides in olive oil over 250 injections with polarity switching.

The Orbitrap Exploris 120 mass spectrometer triggers even more precursor ions for MS/MS with an improved scan rate of up to 22 Hz so you can turn around sample results confidently. If you want to run shorter UHPLC gradients, you can do so with excellent resolution, sensitivity and mass accuracy.

Orbitrap Exploris 120 MS fast scan rate

Quantitation of all compounds in bovine muscle matrix is easily achieved by fast scan speeds, even when multiple precursor ion m/z isolation windows are selected for the DIA experiment.

The Orbitrap Exploris 120 mass spectrometer enables positive and negative mode switching with a single cycle completed in approximately 1.4 Hz. Compared to other high-resolution MS instruments, the mass resolution and mass stability do not need to recover after polarity switching, saving you time.

Full scan MS data acquired for 90 ng/g Zearalenone in corn feed demonstrates preservation of mass accuracy stability during polarity switching.

Being able to focus on your science, rather than experimental set-up through ready-to-use application-specific method templates, means that the next breakthrough is closer than ever before. The Thermo Scientific Method Editor and Tune ecosystem deliver intuitive method programming with pre-defined (yet fully editable) templates for the most popular experiments.

If you’re an experienced triple quadrupole MS user, performing quantitation on an Orbitrap HRAM MS instrument will require the use of different scan modes. There are multiple scan modes, but listed below are the most popular ones. Keep in mind the importance of specifying narrow mass ranges especially if your analyses require increased sensitivity or selectivity. The quadrupole excludes any ions that are not in the user-defined mass range enabling higher quality results.

  • Full Scan MS – most predominantly used due to comprehensive, high-quality quantitative data provided. Once a mass range is defined to capture all relevant ions, rest assured detection of all compounds in that range will be measured.
  • Targeted Selected Ion Monitoring (t-SIM) – used for analyses requiring higher sensitivity because you can set a narrow mass range (as narrow as 0.4 Da).
  • Targeted -MS2 (t-MS2 formerly Parallel Reaction Monitoring (PRM)) – used for analyses in complex samples requiring additional selectivity. A fragmentation-based acquisition mode, Targeted-MS2 provides more selectivity because a high-resolution product ion spectrum is created for only desired precursor ions based on the inclusion list.
