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

SNSadao NAKAMURASKSatoshi KAGAMI

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.

Abstract

簡易熱抽出-GC/TCD法を用いて，インクジェットプリンター用純正黒色インク（液体状）及びその互換品の判別を試みた．試料導入には，ガスクロマトグラフ（GC）の注入口に直接挿入可能なサーマルセパレーションプローブ（TSP）を使用した．DB-WAX UIカラムによる分離により，両インクのクロマトグラム上に明確な差異が認められ，判別が可能であった．さらに，MatchCompareソフトウエアによるクロマトグラムの類似性解析により，数値的な異同判別が可能であった．本手法は簡便かつ実用的なプリンターインク判別手段として有用である．
