Differentiation Between Genuine and Compatible Printer Inks Using a Simplified Thermal Extraction-GC/TCD Method

Key Points

• The aim is to differentiate between genuine and compatible black inks for inkjet printers utilizing a simplified method.
• Utilized a thermal separation probe (TSP) for sample introduction into gas chromatography (GC).
• Employed a DB-WAX UI column for separation of the inks' components.
• Conducted similarity analysis of chromatograms using MatchCompare software.
• Distinct differences observed in chromatograms for genuine and compatible inks.
• Numerical differentiation of similarities was achievable through software analysis.
• The method demonstrated effectiveness as a practical tool for identifying printer inks.
