Spectral Accuracy

What is Spectral Accuracy? In the context of mass spectrometry, spectral accuracy refers to the ability of an instrument to accurately measure the mass-to-charge ratio (m/z) of ions, which is essential for identifying the chemical composition of a sample. High spectral accuracy is achieved by calibrating instruments to obtain high mass accuracy, which is typically expressed in parts per million (ppm). Spectral accuracy is an important measure of the accuracy of a spectral method in approximating the solution of a differential equation, and it is also a critical aspect of mass spectrometry, where it refers to the ability of an instrument to accurately measure the mass-to-charge ratio of ions.

In GC/MS analysis, the abundant EI fragments, with or without the presence of the molecular ion (M+), are highly valuable for identifying unknown compounds. This is particularly the case if the compound is already included in a spectral library such as NIST or Wiley, making it easier to search for and identify the compound.


User testimonials

  • "First let me say, we just finished the first month using GC/ID, and it works really well. Better even than we had hoped. This is really a great tool for us, so thanks for all the work you everyone at Cerno have put into it. "
    NSF InternationalNSF InternationalBenjamin Johnson
  • "We have used your MassWorks for all our publications of this year (for formula ID), we have found that in most of the cases the (mass) error is about 10 ppm" ( using LC and GC/MS single quads in 13 publications in organocatalysis in 2017-2018 all in peer reviewed journals)
    Universidad Autónoma de MadridDr. José Alemán
  • "Your software [MassWorks] continues to amaze. Your first candidate is indeed the unknown -- atranorin [LC/MS]. I'd like to get the software that works with both our Shimadzu GC-single quad and our Shimadzu LC-triple quad."
    Oberlin CollegeDr. Robert Thompson
  • "MassWorks has proven itself on our GC/MSD system for accurate mass measurements and unknown formula ID.  When applied to LC/MSD, it also worked amazingly well to provide accurate mass results for the identification or confirmation of small molecule organic compounds"
    Universidad Autónoma de MadridDr. José Alemán
  • "Starting a little bit "speechless" from our side your Presentation helped really changing our mindset, from "unbelieving" into "believer". After this Test with a sample taken from real life with real interferences my colleagues and I fully agree that MassWorks is indeed a powerful tool for advanced GC/MS analysis. We found that MassWorks is really a "must have" product for us..."
    Researcher from a large German chemical company
  • "I have tested and used the MassWorks software since the summer of 2007. The main purpose for me is using its formula ID feature to confirm the GC/MS NIST library search results for unknown chemical substance identification especially when the [NIST] search match values are similar for more than one compounds. The software is relatively simple to use and most times provides the #1 match for our testing chemicals with more than 200 compounds in a variety of chemical groups."
