Adli belge incelemelerinde mürekkep analizi önemli bir yer tutmaktadır. Tahribatlı ve tahribatsız olmak üzere ikiye ayrılan mürekkep analiz yöntemleri içerisinde ince tabaka kromatografisi (İTK) maliyetsiz, hızlı ve az tahribatlı oluşu bakımından tercih edilmektedir. Bu çalışmada piyasadan temin edilen farklı markalardan toplam otuz adet tükenmez kalem mürekkebinin (on ikisi mavi, onu siyah ve sekizi kırmızı) ilk kâğıda aktarıldığı anda bütanol:etanol:su (9:1:1) çözücü sisteminde İTK profilleri çıkarılarak benzerlikleri ve farklılıkları ortaya konmuştur. Daha sonra farklı koşullarda (oda koşulları, karanlık ortam ve güneşli ortam) altı ay süreyle bekletilen belgelerden elde edilen mürekkep örneklerinin aylık periyotlarla, seçilen çözücü sis...
