Warm, warmer, hot. Tracking organic load at 1,200°C.
The catalyst-free ceramic oven is the centrepiece of the QuickTOCpurity. At 1,200°C, it reliably dissolves all carbon bonds and thus enables a complete analysis of samples. Despite the high temperatures used, absolute safety is guaranteed in all settings. To this end, the QuickTOCpurity can be delivered with a number of different housings, depending on the intended location, enabling the analyser itself to be safely located in highly corrosive environments as well as in Ex-Zones.
The loop injection. For clean sample dosage.
The sample is injected into the furnace via an injection loop. Moreover, this loop defines simultaneously the sample volume. The loop system ensures that the sample is 100% sealed off from ambient air. Even the smallest impurities are excluded. The sample can be analyzed correctly in the lowest ppb range.
Catalysts. For our analysers simply not necessary.
Catalysts are only necessary for a low temperature catalytic "high temperature" oxidation (680 – 1,100°C) to support the oxidisation of the carbon bonds. However, the performance of the catalysts reduces over time. This affects the measurement results, necessitates continual new calibration and eventually requires that the catalysts be replaced. Because of their high temperatures our analysers do not need any catalysts. With the QuickTOCpurity we want to save you the trouble.
TC determination. Quick beneficial.
Inorganic carbon (carbonate) reacts in the boiler to produce carbonic acid, which attacks the metal wall of the boiler, pipes and heat exchangers. The monitoring of total carbon includes this inorganic part and minimizes the risk. In addition, the measurement cycle of the TC determination is only about 1 minute, so a fast and reliable monitoring of ultrapure water is ensured.
Calibration and validation. Fully automatic.
LAR offers with the patented calibration and validation technique QuickCalibration the opportunity to check automatically and remotely at any time the analyser. In contrast to the use of liquid standards, that must be produced or purchased, contributing to expense, our unique method uses a defined gas which remains stable for a long time and is ideal for automatic calibrations without personnel on site.
Contamination of test equipment in the loop system is technically impossible.
The QuickTOCpurity. Ultrafast measurement and maintenance.
The QuickTOCpurity works in batch mode and determines the TRUE TOC in under 3 minutes. The TRUE TC you even get within 1 minute.
The TC is particularly advantageous if a high proportion of the TIC is present. This speed guarantees that very short peaks can be determined very well during a daily cycle. The analyser's availability is over 98%.
Even when used in high salt applications its weekly service is about 30 minutes.
