ONLINE TOC ANALYSER          ENVIRONMENTAL LABORATORY
 
 
TOC Analyser
 
UniTOC- line operates almost free of maintenance, which allows the online TOC determination under optimal conditions in many different fields of applications like pharmaceutical industry, microelectronics, chemical industry as well as the production and surveillance of potable water.
 
For pharmaceutical usage, the model UniTOC-process allows standard suitability test according to USP/Ph. Eur.
It is conform to CFR 21part 11.
 
The UniTOC analyzers oxidize the organic compounds by using a high energy, low voltage UV lamp and the resulting carbon dioxide is detected and measured by CO2 selective NDIR cells.
An internal computer with touch screen controls the instrument and registers all parameters.
Data exchange is achieved by USB interface for digital and analog data, which can be integrated into existing network.
Both instruments can be configured for the reagent-free operation, which can be applied for water with low calcium carbonate content and water containing organic substances below < 2000 ppb.
Qualification of the systems is performed according to IQ, OQ und PQ procedures.
 
Advantages:
 
- All fluidic lines of the instruments are manufactured by materials of highest purity like PEEK, PFA or PTFE with almost no dead volumes.
- Dosage of samples is accomplished by a corrosion free peristaltic pump.
- Two inlets offer double capacity for the sample uptake and TOC measurements.
- UV radiation is generated by a high energy, low pressure UV lamp, which guarantees a lifespan longer than 12 months.
- The CO2 concentration is measured with a NDIR detector system - CO2 selective and sample temperature independent.
- An internal PC with touch screen operation controls and registers all instrument parameters, allows the online visualisation of the TOC value trend.
