Cerno Home 2018

Cerno develops and publishes award-winning mass spectrometry calibration and analysis software which not only enables formula determination at unit mass resolution (single or triple quad) with 100x improvement in mass accuracy (CLIPS), a capability typically reserved only for HiRes MS systems, but also improves formula ID at HiRes by 20x through the Spectral Accuracy concept (sCLIPS).  These dramatic results are enabled through the patented TrueCal™ calibration process and validated by hundreds of publications and thousands of satisfied users across the world.

For unit resolution quadrupoles:

  • 100x better mass accuracy
  • up to 99.9% Spectral Accuracy
  • Confident elemental composition determination
  • Mixture deconvolution for isotope analysis and large molecule deconvolution

For high resolution TOF, Orbitrap, FT ICR:

  • Self-calibrates peak shape without standards for exact isotope modeling
  • Eliminates 95-99% of incorrect formulas with high spectral accuracy
  • Quantitative measurements for biologics degradation analysis

sCLIPS improves formula ID on high resolution mass spectrometers

MassWorks TrueCal™ calibration technology provides advantages for both high and low resolution instruments.  The above left figure shows an almost perfect match (Spectral Accuracy) between a calibrated single quad and the corresponding “True” calculated MS using the CLIPS search.  The figure on the right shows excellent spectral accuracy match for confident formula ID on a high resolution TOF instrument using sCLIPS search.

Quantitation of labeled and unlabeled isotopes

 

Proper mass spec calibration also means that complex mixture deconvolution of overlapping and interfering ions is easy and provides the most accurate quantitative results.  The top figure shows the accurate quantitative analysis of 7 component mixture of a C13 radio labeled pharmacutical using a quadrupole instrument.  The bottom figure shows the ability to detect and deconvolve modified products (glycan conjugates 0 – 10) of a large molecule intact protein (by Maldi) (see ASMS poster). This type of analysis is not possible by other means!

Powerful GC/MS Analysis Software

GC/ID is the first major breakthrough in GC/MS in decades

GC/ID is a fully automated compound identification application that offers new levels of accuracy and confidence in GC/MS qualitative and semi-quantitative analysis.  Based on the new MassWorks Rx configurable platform, GC/ID offers powerful new capabilities to GC/MS including:

  • Uses the industry standard NIST search engine
  • Retention Index (RI) matching provides unsurpassed unknown ID confidence
  • Accurate mass analysis of molecular/fragment ions for confident compound ID
  • Magic Highlighter indicates at a glance the correct match by combining search, RI, and formula ID

The software that started it all…

Easy-to-use post acquisition software | Achieve high Mass Accuracy and high Spectral Accuracy

With over a dozen patents and 1000’s of users, the award winning MassWorks established the performance benchmark for “True” mass spec calibration.  MassWorks is a Windows based desktop software that works with most MS vendor instruments by directly reading the data files making the powerful calibration and analysis technologies available to both nominal and high resolution instruments.  Learn more about it here.

  • "Determining the elemental composition of pure materials at modest resolution typical of quads has never been routinely practiced – CLIPS brings that task very close to practice for the general user. It is not too much of a stretch to suggest CLIPS will enhance the confidence of TOF-based assignments as well, which may even challenge slower FTMS-based determinations."

  • "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
  • "With PFTBA calibration performed to each GC/MS run, mass accuracy better than 10mDa can be achieved and Spectral Accuracy of better than 99% can be achieved to help attain reliable formula determination. The mass calibration is stable after 11 days without significantly compromising formula determination. While mass calibration is more susceptible to time related variations, the Spectral Accuracy has been shown to be robust enough for formula determination after 19 days." -Click here to read full presentation

  • "The program is very easy to learn, it literally took minutes to get the first exciting results. On our 10 year-old triple quad, we manage to achieve mass accuracies of 10 ppm or better, routinely! It has become an integral part of our characterization pipeline for newly synthesized compounds."
    University of ViennaDr. Alexander Leitner
  • "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)
