Total Chlorine Analyzer – HELIOS CL
The Eraly HELIOS CL Total Chlorine Analyzer excels in measuring Total Chlorine(Halides) from trace levels (<0.5 ppm) to high concentrations (>80%) in various sample matrices including liquids, solids and gases.
This advanced analyzer is utilized in refineries, environmental monitoring, industrial applications, and research laboratories.
HELIOS CL is also effective for analyzing chlorine in chlorinated PVC-C. Additionally, it comes with accessories for EOX and POX measurements and includes comprehensive equipment for AOX dosing through agitation and absorption.
Two configurations are available :
- For only liquid (including viscous) and gas samples.
- For the measure of Total Chlorine in AOX, EOX, and POX, including all sample matrices.
CHLORINE ANALYSIS
Total Chlorine in liquid, gas and LPG samples
HELIOS CL Total Chlorine analyzer with an advanced single shot auto-injector or the Mini-Autosampler with 6 test positions and�?the autosampler with 50 positions made measuring total chlorine in liquid easier.
The Autosampler (G-PSR) handles the injection process for gas and LPG samples.
These automated systems allow seamless sample injection into the Pyro-Combustion furnace for accurate measurements.
Total Chlorine in Solid and AOX, POX and EOX samples:
Samples were directly introduced to the Pyro-combustion furnace with a boat or cup.
Samples must be pre-teated with the batch or column method for AOX.
If the sample is inert to the electrolyte, direct measurement can be performed by injecting the sample directly into the titration cell, bypassing the need for the combustion system.
For halides in liquids or emulsions, direct measurement is possible. Similarly, suspensions and solids can be treated if the halides to be measured are extractable.
Advantages of HELIOS CL:
- Absolute Titration Method: Utilizes an absolute titration method with auto-calibration, eliminating manual calibration. A manual calibration option is available.
- Automated System: Replaces the H2SO4 absorber with an automatically managed drying/flushing system. There is no manual handling of acids required.
- Wide Measurement Range: Capable of measuring very small (0.1 nano Faraday) to very large (100 nano Faraday) current.
- Flexible Calibration: Software supports various calibration methods and ranges, which can be saved for future use.
High Performance and Flexibility
The HELIOS CL Total Chlorine analyzer offers unparalleled accuracy, repeatability, and reliability. It features two titration cells that can be used simultaneously, reducing the need for frequent electrolyte replacement and saving time and chemicals. This design minimizes pollution and enhances sensitivity and accuracy.
- Medium Volume Cell: For samples ranging from <1 ppm to 3000 ppm.
- Large Volume Cell: For samples from 1000 ppm to 80% (without dilution).
HELIOS CL provides three types of electrolytes:
- Very Low Concentration: For traces (<1 ppm).
- Low Concentration: For samples 1 ppm to 3000 ppm.
- High Concentration: For samples 1000 ppm to 80% (without dilution)
