Basic methods were examined for analytical chemical monitoring at chemical weapons facilities. The database for this monitoring is found in a separate section 1-KhO of the State Register of Measurement Methods, which is part of the Federal Information Foundation for the Assurance of Measurement Uniformity. These monitoring methods are based on analysis of the project design documentation of chemical weapon destruction facilities and have emerged from investigations in chemical weapon disarmament over the past 11 years, in particular, at the Inversiya Technology Center.
