Laboratory scientists in South Korea continue to implement chromatography techniques in order to identify the cause of an explosion that sank one of its navy vessels.
Officials in the country are said to be exploring the possibility that North Korea may be involved following tests proving the blast did not occur internally or through contact with reef due to no melted wreckage being discovered inside the boat, the Korea Herald paper reports.
The news provider noted
liquid chromatography, gas chromatography and mass spectrometry are currently being used to examine fragments from the ship.
Government authorities are speculating that a mid-sized torpedo with a warhead weighing more than 200kg caused the detonation, which killed 40 and has left 6 missing.
Analysis of ship fragments is currently being undertaken by a team of 130 researchers across the globe.
The Herald previously reported that efforts to obtain these pieces were originally hampered by poor weather conditions.
