Interpret a Chromatogram

Systematic interpretation of GC and HPLC chromatograms covering system suitability verification, peak identification, integration, calculation of chromatographic parameters, and assessment of peak quality for confident qualitative and quantitative results.

When to Use

• Reviewing chromatographic data before reporting analytical results
• Verifying that a system suitability test passes before running a sample sequence
• Identifying unknown peaks or confirming known analytes by retention time or spectral data
• Troubleshooting unexpected peaks, baseline anomalies, or integration artifacts
• Training analysts on chromatographic data interpretation

Inputs

Required

• Chromatogram data: Digital or printed chromatogram with time axis and detector response axis
• Reference standard data: Retention times and responses of known analytes under the same method conditions
• Method parameters: Column, mobile phase/carrier gas, temperature/gradient program, detector settings
