The MicroMac 1000 is designed to operate as a free standing colorimetric analyser which gives the user the ability to get ‘live’ data from a site for a short period of time without having to install complex online monitoring packages.
The portability of the analyser gives the user a portable ‘laboratory’ as it uses the same standard methods of analysis as most laboratories. It can be used as a tool for site surveys, investigations or when set up as a package, longer term studies or profiling of a site. With the advantage of ‘live’ results the system can be used in place of samplers where the sample is collected and sent away for laboratory analysis, thus enabling changes to be made much quicker.
The analytical methods used in the MicroMac 1000 are based on the standard methods that are used in laboratories throughout the world. Many of these methods have their basis in the “Methods for the Examination of Waters and Associated Materials” as published by HMSO – Standing Committee of Analysts.
The Loop Flow Analysis system can be configured as a single or multiple chemistry module: The multiple chemistry module can have up to 4 chemistries or 7 reagent additions. The chemistry module shown shows a typical analysis loop, this can include a high temperature heating bath for hot acid digestion and high pressure valves and PTFE tubing in all areas in contact with the acid or high temperatures when required.
Up to seven reagent valves allow the analyser to be configured for multiple chemistries, typical combinations include:
