The chemist, who is the only Malaysian with a doctorate in chemical weapons analysis, said laboratory tests also detected VX acid, a degraded product of the nerve agent, on Aisyah's sleeveless T-shirt. He said VX will degrade once it is exposed to the atmosphere, and even faster when it is in contact with water. "The presence of VX precursors and VX degradation products confirms the presence of VX itself," he told the court.
