ProcessTRACE
On-line Monitoring
ProcessTRACE is a special solution provided by TRACE Analytics for on-line operations to monitor microorganism cultures.The analysis of glucose in culture media requires sampling under sterile conditions, while ensuring reproducibility and relevance of the sample. Three sampling options are available with ProcessTRACE: filtration probe, dialysis probe (patent pending) and bypass module. All systems enable reliable sterile sampling directly from the bioreactor.
|
|
| ProcessTRACE is primarily used for on-line monitoring of industrial or laboratory cultures. For all types of cultures (batch, fed-batch, continuous culture), continuous glucose analysis using ProcessTRACE can be carried out. Individual sampling for on-line and off line analysis is feasible. |
 |
ProcessTRACE consists of a housing tailored to the specific application and environmental conditions. The front panel comprises all the mechanical elements. The electronics are of modular design and allow a multiple data output.
The analysis is performed with support of a sensor unit, which consists of an electrochemical biosensor. System control and data processing are achieved via application-specific, user-friendly software. |
