Mettler-Toledo Thornton 7000RMS real-time microbial monitoring system

Mettler-Toledo Thornton has announced its 7000RMS analyser for real-time, continuous measurement of bioburden in the pharmaceutical industry. The technology will assist companies in validating water systems in real time, thus reducing offline sampling costs and helping to eliminate false-positive tests.

The product provides continuous analysis of microbial and inert particle contamination wherever required in a water system or at point of use. The compact unit not only provides real-time assessment of water loop bioburden levels, it lowers labour costs via reduced sampling and testing; reduces energy use through better management of sanitisation cycles; and leads to increased process understanding and product safety.

The laser-induced fluorescence (LIF) technology employed in the system does not require time-consuming staining or use of reagents. The implementation of LIF in the analyser, in conjunction with Mie scattering detection and advanced software algorithms, allows the simultaneous measurement of particle numbers and determination of whether particles are microbes or inert material.

The product is suitable for online and at-line use, and for lab measurements of grab samples. It features Wi-Fi capability, a touch-screen user interface, multiple data communication options (including SCADA connectivity with ModBus TCP) and multiple analog outputs.
