Das OPCW hat sich nach der Sitzung heute morgen geäussert:
Das BZ war eine Vergleichsprobe und diente zur Qualitätssicherung, wie schon vermutet.

"As it was clearly shown in the detailed and technical presentation, we should not have an iota of doubt on the reliability of the system of the OPCW Designated Laboratories. The Labs were able to confirm the identity of the chemical by applying existing, well-established procedures. There was no other chemical that was identified by the Labs. The precursor of BZ that is referred to in the public statements, commonly known as 3Q, was contained in the control sample prepared by the OPCW Lab in accordance with the existing quality control procedures. Otherwise it has nothing to do with the samples collected by the OPCW Team in Salisbury. This chemical was reported back to the OPCW by the two designated labs and the findings are duly reflected in the report."
Lawrow oder seine Fachleute scheinen sich also doch verlesen zu haben und hielten wohl die Analyse der QA Probe für den eigentlichen Analysebericht.
Mal sehen was sie jetzt sagen, laut britischer Presse laufen die polizeilichen Ermittlungsarbeiten immer noch und werden wohl bis Ende des Jahres andauern.
