The increasing general awareness of atmospheric pollution and its hazards to the health and wellbeing of industrial workers is bound to result in greater stress on accurate, reliable and frequent assessment of work place pollution and worker-exposure. Enviro Instruments Handy Sampler EI- 007 has been developed to fulfill this critical need. The EI-007 system uses a small battery operated pump to draw air thorough a suitable absorption solution contained in an impinger. If necessary, 2 impingers can be used in series to monitor 2 gaseous pollutants. There is an additional provision to determine suspended particulates in the same exercise by using the open sampling head which takes 25mm diameter filters.

Since the EI-007 sampler uses wet chemical methods to sample gaseous toxicants, the same hardware can be used to sample a variety of pollutants including oxides of sulphur and nitrogen, halogens, ammonia, sulphides, etc. The particulate sampling head provided with the system would be useful for monitoring particulates like silica, cement dust, metal fumes, asbestos fibres, etc in work areas of cement plants, foundries, etc.
