Liquid chromatography used in salvaged ship analysis

Liquid chromatography is being used by laboratory experts to reveal why a South Korean navy ship sank last month.

According to the country's Herald newspaper, researchers are utilising both liquid and gas chromatography, three-dimensional cameras and a mass spectrometer to examine the wreckage.

The news provider noted that attempts to salvage the bow of the Cheonan vessel have so far proved unsuccessful due to unfavourable weather conditions.

Early indications show a torpedo explosion occurred underwater that released a bubble jet that tore apart the ship, with lab scientists looking at gunpowder residue found at the scene.

So far, 38 sailors have been confirmed dead, while investigators continue to search for the bodies of the eight remaining members of the crew.

The Chosen Ilbo newspaper recently reported that North Korean authorities deny their armed forces had any involvement in the incident, although the information source noted South Korean officials remain sceptical at the announcement.
