In the OPCW samples of Salisbury the substance BZ was not detected

From the statement by the OPCW Director General of 18 April:

"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."

International conferences in Spiez:

Schedule 1 Users Forum

22 - 25 January 2018

Image- Third Workshop on Designated Laboratories

Switzerland1  hosted, in cooperation with the OPCW Technical Secretariat, the second workshop on Schedule 1 facilities, the “Schedule 1 Users Forum” from 22 – 25 January 2018 at Spiez Laboratory. The objective of the workshop was to bring together practitioners of Schedule 1 facilities and to give them a unique platform to share their experiences. The first OPCW edition of this workshop was hosted in Madrid2  in January 2014 by the Government of Spain.

The program of the workshop was divided into different sessions, and participants were invited to an informative lab tour. Topics included equipment, installations, materials used, safety and security as well as related issues.

In total, 43 participants from 15 CWC States Parties and from the OPCW Technical Secretariat attended the workshop. Participants supported the suggestion to continue this workshop in the future.

Third Workshop on Designated Laboratories of the UN Secretary-General’s Mechanism

Image- Third Workshop on Designated Laboratories

The UN has invited its Member States to designate analytical laboratories that are capable of supporting an investigation of alleged use of chemical or biological weapons in accordance with the United Nations Secretary-General's Mechanism (UNSGM). In contrast to the existing strict quality assurance measures in the field of chemical weapons, similar controls are inexistent in the field of biological weapons. To this end and based on the findings of previous discussions, Spiez Laboratory organized a third workshop from 20-22 June 2017 with the goal to kick-start practical work open to all interested laboratories on a voluntary basis. As a result from the workshop, future efforts are geared towards quality assurance exercises that will eventually lead to the formation of a robust network-like structure of participating laboratories.

Appointment of Stefan Mogl as Director UN Investigations Office

The United Nations, in co-operation with the Organization for the Prohibition of Chemical Weapons (OPCW), has set up a joint investigation committee in 2015 to identify the perpetrators of chemical weapons operations in Syria. Stefan Mogl, Head of Chemistry division of Spiez Laboratory, was appointed by the UN as Director Investigations Office until November 2017 for the second phase of the investigations. As former OPCW inspector and head of the OPCW Laboratory, Stefan Mogl has profound professional experience in this field. As an independent expert, Stefan Mogl will mainly be responsible for the professional coordination of the investigations and the investigation report.

Switzerland has consistently been active in strengthening the Chemical Weapons Convention and the OPCW. The convention, which is binding according to international law, prohibits the development, production, stockpiling, dissemination, transfer and use of chemical agents and obliges all member states to disclose and destroy their chemical weapon stocks. The appointment of Stefan Mogl also strengthens the presence of Swiss citizens in bodies of international importance.

OPCW Director General Ahmet Üzümcü opens the Spiez CONVERGENCE workshop on 6 September 2016

Ahmet Üzümcü at the Spiez CONVERGENVE Workshop

The Director-General emphasized in his opening remarks that, in the future, the OPCW’s activities will focus on preventing the re-emergence of chemical weapons, with special attention being given to challenges posed by the ambitions of terrorist groups to make and use chemical weapons. Meeting this challenge would require heightened vigilance, including ensuring that efforts to prevent proliferation evolve with advances in science and technology.

Analytics of Zika virus

Among other issues, the Biology Division of Spiez Laboratory is concerned with the identification and diagnostic of freshly occuring or reoccuring pathogens, one of them being the zikva virus. The respective detection methods are established at Spiez Laboratory since mid-February.  The zika virus, which is transmitted by mosquitos (probably by the genus Aedes), is found in Africa, Asia, the Pacific Area as well as Central and South America. It may cause a flu-like, generally mild disease. In addition, there is evidence that infections during pregnancy may cause malformations of the skull and brain of the fetus.

Leading biological laboratories for the United Nations

The UN has invited member states to designate analytical laboratories that are able to support an investigation of alleged use of chemical or biological weapons in accordance with the United Nations Secretary-General's Mechanism (UNSGM). An international workshop from 9 to 11 November 2015, organized by Spiez Laboratory, will discuss the necessary steps to establish a global and functional network of analytical laboratories for biological weapons. To gain full acceptance, such a network must meet similarly stringent requirements as are existing for analytical laboratories for chemical weapons.
