Improve efficiency and save time for science with GC/ID, a powerful and fully automated application that provides quick and accurate identification, confirmation, and quantitation of both Target and unknown compounds.

Challenges with Library Search

Despite its huge popularity, library search results are often ambiguous and in some instances can fail to produce any useful results. This is due to several reasons, including unresolved chromatographic peaks (mixtures), column bleed and background interferences, the spectral similarity of closely related compounds, or the absence of the compound in the library. As a result, it’s essential to explore alternative search strategies to ensure you get the results you’re looking for rapidly and with confidence.

Built in Analytical Expertise

Confident Unknown ID typically requires a high degree of user expertise and can be tedious and time-consuming.  Typical tools available to the analyst to address these challenges include:


GC/ID is the only processing software that incorporates “Composite Scoring” in a fully automated system that is fast and easy to use, turning every analyst into an expert. The results are processed and presented in a way that enables any analyst to review and interpret runs in minutes instead of hours.

Unlock the full potential of your spectral analysis with GC/ID. Our advanced technology performs deconvolution and accurately identifies the peaks present. With Cerno’s “Magic Highlighter,” you can easily color-code your compounds and obtain a clear visual representation of your data. The IS, surrogate, and target compounds are highlighted in a vibrant green color and prepended with a prefix. Don’t settle for less – choose GC/ID for reliable and precise results.

Extractables and Leachables


National Water Testing Lab

Average 8,000 Samples Annually and Manually

A national water testing facility on average, processed 7-8,000 samples a year, which was a manually intensive process, requiring highly skilled domain experience. The analysts must know chromatography and mass spectrometry extremely well and understand the chemistry involved.  All samples require extensive evaluation and throughput is slow.

Testing Drinking Water Equipment

There were two primary drinking water standards: Standard 60 and Standard 61. While both standards use the same analysis, Standard 61 specifically focuses on extractables and leachables.

Water system components undergo conditioning for several days as per Standard 61. After that, they are exposed to the test water, which is collected and then tested for a variety of target compounds. The samples are also analyzed using a modified version of EPA 625 through GCMS scans for unknown and tentatively identified compounds.


  • 7-8,000 samples evaluated annually by a team of 3-4 scientists
  • The established workflow was tedious, with analysts manually combing through spectra and chromatograms, evaluating every chromatographic peak individually. One by one
  • “Dirty” samples could sometimes take hours or even days to process, with hundreds of unknown peaks
  • Reviewing complex matrices for co-elutions or other chromatographic interferences required intensively trained analysts and lengthy data review
  • Once identified, quantitation was also tedious and manual
  • Report generation and LIMS integration were done with a complex Excel macro that was difficult to maintain
  • Delays created long sample backlogs.

Additional Challenges

  • Average sample processing time estimated at 30-40 minutes
  • Limited staff available
  • Years of highly skilled training required
  • Difficult and costly to replace staff
  • Process could not be implemented in other labs/regions
  • Assignments often required judgment calls based on skill and experience


Time Savings, Workflow Automation, Confident Results

GC/ID Version 5.0 Solution

The new GC/ID platform has made the process faster, saving time, skilled resources, and removed our backlog. Pre and postprocessing eliminates the manual elements of the process and presents only relevant information to the analyst. Most of the analyses can be performed by chemists with less rigorous training, allowing specialists to focus on difficult/complex matrices..

  • GC/ID chosen as the vendor-neutral platform
  • Compatible with all commercial GC/MS systems
  • Fully automates peak deconvolution and quantitation
  • Provides superior identification confidence by combining library search, retention index (RI), and accurate mass validation in an automated full-run analysis
  • Modern Python scripting allowed for fast and easy NSF specified customizations to be delivered ahead of schedule


  • Samples processed as they are run. No backlog
  • Complex samples processed within 3-4 hours instead of days
  • With automatic deconvolution and composite scoring, the report is 90% done by the time the analyst reviews it
  • Estimate half of the samples run are clean. 80% have three or four TICs. These can be evaluated instantly by analysts with less training
  • Dirty samples still require work, using GC/ID will identify what’s  captured; it will take just minutes.
