Product Description

Continuous Online Total Organic Carbon Measurement

Analytical Method:
The Model 3S TOC Analyzer, by ECD Analyzers,  utilizes the method of UV persulfate oxidation, detection of generated carbon dioxide using a Non Dispersive Infrared Detector (NDIR), which conforms to EPA, DIN, CE, ASTM, NAMUR regulations.

An alternative TOC analytical method is a UV correlation technique. This analytical method is used in the Model UV6 Analyzer. For more information view the product page for the Model UV6 Analyzer.

Measuring TOC continuously online is the perfect solution for monitoring contamination and discharges. The TOC Analyzer measures total organic carbon in liquid samples using the method of UV persulfate oxidation with subsequent carbon dioxide detection by nondispersive infrared absorption (NDIR). The analyzer can measure TOC in liquid samples ranging from 0–5 mg/L to 20,000 mg/L. The method conforms to EPA, DIN, CE, ASTM, and NAMUR regulations as well as meeting the requirements of ISO and EN directives.

Safe Operation in Case of Sample Loss
The fast loop reservoir has a floating level sensor. If no sample reaches the reservoir for more than a preset time, the analyzer switches automatically to standby mode. As soon as the sample flow restarts, the analyzer switches back to the analysis cycle automatically. Air bubbles are removed in the reservoir before the sample enters the analyzer.

Dual Compartment Enclosure
The analyzer consists of two separate housing compartments in order to separate the electronics from the wet part.

Analysis Process
The sample first is acidified and then sparged to remove inorganic carbon. The remaining liquid is mixed with sodium persulfate and digested by two high-performance reactors. The resulting CO2 is then stripped from the liquid and, after drying, its concentration is measured by a NDIR analyzer.

Digital Flowmeter
Unlike traditional analyzers where the flow is controlled by a glass tube rotameter, the carrier gas flow is controlled digitally and is displayed in cm3/min. The flow is monitored and in the case of an abnormal value such as a line blockage, the analyzer stops automatically and displays a «low carrier flow» message.

Safe and Reliable Online TOC Measurements
Separate lines for stripping gas and carrier gas There are two separate gas lines, each with its own compressor. One is intended for the stripping gas for the TIC (total inorganic carbon) and one for the carrier gas (automatically monitored by a digital flowmeter).

Integrated carrier gas
An internal air compressor produces the carrier gas for the oxidation and detection stages. The air is purified using an internal soda lime filter which means that there is no need for external air treatment or a compressed air supply, as in traditional analyzers.

Autoclean
This function uses a dedicated peristaltic pump to clean the liquid lines of the analyzer, the sample line, and the external reservoir.

Automatic ZEROGAS checks
The ZEROGAS value is expressed in ppm and specifies the residual CO2 concentration value in the carrier gas (ambient air filtered through a soda lime filter). During a ZEROGAS cycle, the pumps and UV lamps are switched off and the carrier gas passes through all the wet cells to the IR detector. The detected CO2 concentration is stored in the analyzer as the ZEROGAS value. A ZEROGAS cycle can be started manually or automatically at a time and interval selected by the operator. If the ZEROGAS value exceeds a certain preset limit, the alarm «ZEROGAS too high» will be activated and the analyzer will stop.

Materials Used in the Analyzer
All materials used are chosen for their long life and reliability. The design uses the minimum number of fittings. All of the materials used are resistant to the corrosive liquids used during operation.

TOC or TC
The Analyzer is also available as a total carbon (TC) analyzer. Here the step of sparging the acidified sample is omitted. Along with a high volume external pump, this offers faster response times when the total inorganic carbon (TIC) in the  sample is considered insignificant.

SIMPLE OPERATION – FULL CONTROL
The user interface is a touchscreen located on the front of the analyzer. All output/input data, status information, alarms, and fault conditions are shown. Simply pressing the touchscreen buttons gives access to commands and settings; access to the system configuration and timings is protected by a password.
