GC-LC Concordance functionalities and features

GC-LC Concordance software for the automatic comparisons of complex chromatograms with the automatic compensation of the retention time shiftings by a neuronal treatment (up to 100 millions of calculations per comparison).

Compatibility: Windows NT, XP, VISTA, 7, 8, 10
User-friendly interface - only three screens to manage everything in QC mode: Settings, Data entry, Visualisation of the comparison + one PDF report
Only one more screen in Retention Index for the identification of a molecule or a raw material
Possibility to call GC-LC Concordance from an external software and vice versa

Acquisition from any brands in the market (Agilent, PerkinElmer, Thermo Fisher Scientific, Waters, Shimadzu etc.)
Acquisition from any type of detectors in GC, LC, GC-MS (FID, MS, ECD, MPD, UV etc.)
Data acquisition from Servers

Fast entry of one or many samples and one or many and different control samples - up to 500 per sequence
Possibility to link control samples to coded samples automatically
Entry of one chromatogram to be compared to thousands of chromatograms on one line of a sequence (Applications: e-nose, counterfeiting, the origin of a product etc.)
Automatic creation of a sequence after the comparison of one to thousands of chromatograms
Entry of one or many different alkanes chromatograms in Retention Index mode in the same sequence (E.g. Polar and Non Polar)
Run the automatic comparison of one, many or all the lines of the sequence with one click

Filters to remove background noise and saturated peaks
Customizable relative and absolute tolerances between the peaks area of the sample and the control sample
Thresholds of concentrations to control each peak following norms or specifications imposed by your clients
Possibility to work on the full chromatogram fingerprint or only a portion of it
Protection of the method of the sequence with a password

One page to see in a graphic and in a table the results of the comparison between two chromatograms (missing peaks, out of tolerance etc.)
View all the peaks or only the peaks out of tolerance and missing in the table
Continuous zoom on the same page to better visualize any part of the comparison of the two chromatograms
Comment/add the name of the molecules of any peaks
Possibility to transfer all the information added to your control sample to a new control sample in two clicks
Possibility to add new peaks in a control sample (E.g. for the control of allergens etc.)
Possibility to substract a raw material in a mixture
Possibility to switch to manual mode to match up to 6 couple of peaks (for specific applications)
Possibility to mix many control samples into one averaged control sample
Possibility to memorize the profiles of two columns (for specific applications, E.g. RT realignment and creation of a new chromatogram with RT correction)
Possibility to enter a response factor for one or many groups of peaks
Possibility to enter specific concentrations (Quantification)

The automatic retention time conversion into retention index with a chromatogram of alkanes or any other indices reference (internal or external)
Add your own database of molecules and raw materials
Molecule identification with your own retention index database of molecules
Raw materials identification with your own retention index database of raw materials
Cross the identification with two databases for a precise identification (polar and non polar)
Cross the identification with the formulation of your product
Graphic identification of a raw material in a mixture with the estimated concentration of the raw material with one click
Automatic identification of each peak of your chromatogram with a database of RI (E.g. Allergens, DB, WAX…)

Full report with all the peaks, or report with only the peaks out of tolerance and the missing peaks (with colors and signs to identify quicker)
One matching score between two chromatograms based on three different calculations
Report with QC and/or Norm information
Presence of the personalized threshold on each peak of the chromatograms
Export of the data in the report into a CSV file (Excel…)
Possibility to create a new chromatogram with the corrected retention time.
