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.

Implication

Experimental method identifies genuine and compatible printer inks, suggesting a practical approach for differentiation.
