  1. OPEN QUESTION.

describe briefly IMS and FAIMS/DMS techniques

IMS is an analytical method used in chemistry to separate ions in a gaseous phase. The techniques use an electric field, in the presence of a buffer gas, to pulse ions through a drift tube. The buffer gas opposes the movement of ions. Therefore, as the ions transverse the drift tube, they collide with the buffer gas molecules (University of Florida, 2015). IMS identifies ions according to their mobility which is directly proportional to its velocity and inversely proportional to its electric field.

FAIMS/DMS is an analytical technique used to separate ions in a gaseous sample. It uses a continuous and allows real-time analysis of the sample. FAIMS can be used alone or coupled with IMS for better performance. Unlike IMS, FAIMS uses differences in ion mobility in both high and low electric field. It works under standard temperature and pressure conditions. RF voltage is varied between high and low fields to enable a carrier gas to sweep the ions through a cell (University of Florida, 2015). At a higher electric field, the ions mobility becomes electric field dependent.

What is the new EU regulation on classification, labelling and packaging about?

As from June 2015, the European Union (EU) reviewed the classification and labeling of mixtures. According to the new requirement, the classification, labeling, and packaging (CLP) regulation will be the only law that would be used to classify and label both substances and mixtures. CLP regulation is to ensure protection both the environment and health while allowing free movement of substances. The EU CLP regulation forced relabelling of items such as detergents, paints, and industrial mixtures.

  1. OPEN QUESTION.

Riot control agents (RCAs) were the topic of long and heated debates during the CWC negotiations. At issue were their inclusion in the treaty and the restrictions that would be imposed upon their use. In the end, a compromise was reached. How do the rules that apply for RCAs differ from that of those that apply for CWAs?

RCAs also belong to the category of CWAs. However, after a comprise was reached, State Parties were allowed to use RCAs for law enforcement purpose only. State parties to report to OPCW RCAs they possess for law enforcement use. RCAs is prohibited to be used as warfare. On the other hand, CWAs are prohibited for use for any purposes whatsoever and State Parties are required to destroy their stockpiles of CWAs as scheduled by the OPCW.
