Central analytical database

OPCW Central Analytical Database is available on CD ROM to States Parties of the CWC through the OPCW. 

The HP5MS column used in OPCW Bruker 640S GC/MS systems is a carefully chosen brand of capillary column, which gives retention indices very similar to those contained in OCAD (OPCW Central Analytical Database). 

Two certified floppy disks with copies of on-site OPCW Central Analytical Database (OCAD) are issued.

The OPCW Central Analytical Database (OCAD) is compiled and maintained by the OPCW Laboratory and contains analytical data of the chemicals that fall under the Chemical Weapons Convention (CWC) (1). States Parties (SPs) of the CWC and the OPCW (Organization for Prohibition of the Chemical Weapons) Laboratory submit analytical data for inclusion to the OCAD. These analytical data are peer reviewed by experts. Before the analytical data are included into the OCAD, they undergo a technical and political approval process.

Verification of the Chemical Weapons Convention (VERIFIN). The spectra are presented in their original form (size reduced from A4) to show layout and format of library spectra that have been acceptable to the Organization for the Prohibition of Chemical Weapons (OPCW) Central Analytical Database (OCAD). The experimental conditions shown are the standard conditions used by the laboratory for the particular experiment. 

The OPCW has collected reference infrared as well as mass and NMR spectra, since 1994. First, a hard copy set of these spectra was made available for States Parties to the Convention, that is, countries that have ratified the CWC, in 1999. At the time of writing this article, in August 2004, the 7th version of the OPCW Central Analytical Database (OCAD) has been released. It used to be distributed on a CD, but as the size of the database has been growing it... 

Dr. Mesilaakso is currently Acting Director of the Finnish Institute for Verification of the Chemical Weapons Convention (VERIFTN former CW Project) at the University of Helsinki. Before this, he worked at VERIFIN as a Research Scientist, Quality Manager and Research Director. He is a member of the Finnish National Authority of the CWC, a member of the Scientific Advisory Board for the Defense of Finland, and a member of the OPCW Validation Group for data evaluation to the OPCW Central Analytical Database. 

C-I/DEC.64 adopted by the Conference of the States Parties at its First Session on 22 May 1997 and entitled OPCW Central Analytical Database . The lists of validated analytical data for inclusion in the database have been subject to frequent updates, as reflected in numerous decisions adopted by the Executive Council ... 

The First Session of the Conference of the States Parties requested the Director-General to establish a consultative mechanism for updating the OPCW Central Analytical Database to enable the Executive Couneil to recommend proposed inelusions to the Conference for adoption (C-I/ DEC.64, dated 22 May 1997). 

The Executive Council proposes that a eonsultative mechanism be established by the Seeond Session of the Conference of the States Parties to enable approved validated spectra to be plaeed on the OPCW Central Analytical Database. The eonsultative mechanism should be implemented in the following manner ...
