dc.description.abstractInk analysis plays an important role in the examination of questioned/fraudulent documents in a forensic lab. Recent studies of a fairly new analytical technique, capillary electrophoresis (CE), have been conducted and have proven CE to be an efficient analytical technique for the separation of inks. CE is known for its high resolution power and efficiency, requiring a small sample volume, and its capability of separating charged compounds. In this study, capillary electrophoresis was proven successful in the separation of ballpoint and felt tip pen inks using two buffer systems; a 50mM borate buffer, pH 9.3, with 30mM SDS and 25% acetonitrile, as well as a 50mM borate buffer, pH 9.3, with 20% methanol. Electropherograms of 10 inks ofvarious colors and origin were analyzed and sufficiently distinguished from each other.en
