LetzTOC – MEASUREMENT, ANALYSIS,
ONLINE MONITORING
The LetzTOC measuring device was developed by us in-house for monitoring pharmaceutical water.
It allows the total organic carbon content in a sample to be determined. LetzTOC complies with all European, American, and Japanese pharmacopoeia specifications for monitoring PW, WFI or pure steam.
ONLINE MONITORING OF THE FINAL RINSE
The unit can also be used for online monitoring of the final rinse at higher TOC values,
for example following contamination.

LetzTOC: INFRARED SPECTROSCOPY BY NDIR DETECTION
LetzTOC uses UV light to oxidise organic substances to CO2, which is then measured by infrared spectroscopy. The use of the infrared detector reduces the risk of false TOC readings.
Step 1: Expulsion and measurement of inorganic carbon (TIC)
Schritt 2 Oxidation und Messung des organischen Kohlenstoffes (TOC Gehalt)
BY THE WAY:
Our online TOC system can be used to measure the total organic carbon in both hot and cold water. You can easily analyse the data and archive it with our LetzData software via USB. We also offer certified test solutions for calibration and system suitability testing.
As a pharmaceutical water specialist, we do everything we can to ensure you can rely on our quality – including measurement equipment and tools for reliable testing.
Infrared spectroscopy – 2 online channels
Measurement of hot-water and cold-water samples
Touch panel for control and visualisation
Easy to use, easy data evaluation
Certified testing solution (SST, calibration)
In addition to our own LetzTOC system, we rely on tried and tested online TOC measuring systems from renowned manufacturers of generator systems and storage and distribution systems and, of course, we also offer the appropriate services for these systems, such as calibration, SST testing, etc.
