FOI expects to take two weeks examining the samples at its laboratories in Umeå, located along Sweden's northern coast. TV4 reported that other samples were taken to Finland for analysis.
UN inspectors collected the evidence on August 26, five days after an alleged poison gas attack against Syrian opposition rebels. Åke Sellström, a Swedish scientist heading the team of the weapons inspectors, said the number of days between the attack and the team's sample collecting should not affect the analysis.
"On the contrary, it's rare to collect samples this close after the event," Åke Sellström told the Swedish news agency TT.
