Oxidation Reduction Potential or Redox is the activity or strength of oxidizers and reducers in relation to their concentration. Oxidizers accept electrons, reducers lose electrons. Examples of oxidizers are: chlorine, hydrogen peroxide, bromine, ozone, and chlorine dioxide. Examples of reducers are sodium sulfite, sodium bisulfate and hydrogen sulfide. Like acidity and alkalinity, the increase of one is at the expense of the other.
Chlorine levels in liquid hydrochloric acid (HCl) are precisely and safely monitored by means of AppliTek’s EZ-HCl process analyzer. On-line measurement of chlorine in liquid HCl guarantees the purity of the end product. An additional possible reason for the measurement is that chlorine is an indicator for the amount of excess hydrogen in the synthesis of hydrochloric acid.
The purpose of determining impurities in dry chlorine (after compression) is a quality control measure to avoid contamination and off-spec product batches. Alternatively, chlorine purity can also be determined by measuring absolute levels of chlorine in dry chlorine, by means of multi-wavelength UV analysis.
Determining chlorinated organics in waste water of the oxychlorination process is for reasons of environmental compliance. The on-line analyzer system uses a scrubber system where a carrier flow is bubbling through the water. The vapor phase is measured by a Flame Ionization Detector (FID) and is a measure for chlorinated organics of the water.
The purpose of monitoring calcium and magnesium levels in hydrochloric acid is to control brine acidification in chlorine electrolysis, which can be precisely monitored by means of AppliTek’s UPA Universal Process Analyzer.
The purpose of determining residual chlorine in liquid EDC (ethylene dichloride) is to protect decrease risk of corrosion and damage to production units downstream. For all other analytical solutions in the chlorination process, please browse the On-line Analyzers Suite under Products & Solutions.
The purpose of determining ethylene in the chlorination process is to minimize ethylene losses by feedback control of C2H4 / Cl2 ratio in the chlorination reactor. The on-line analyzer system uses selective C2H4 measurement by means of multi-wavelength infrared with automatic optical span possibility. For all other analytical solutions in the chlorination process.
The purpose of determination of moisture in dry chlorine is threefold: prevent corrosion, prevent formation of ferric chloride and control the overall drying process. AppliTek offers two different solutions for determination of moisture: one traditional method by means of an amperometric phosphoric pentoxide (P2O5) electrochemical cell, or a more advanced technique based on tunable diode laser technology (TLDS). Both analyzer systems are installed in a compact protective corrosion resistant cabinet.
As a specialist manufacturer of analytics, AppliTek is your one-stop-shop for state of the art analytical answers to the specific needs of the chemical industry. Ethylene dichloride (EDC) is a chemical liquid that is not found naturally in the environment, and classified as a hazardous chemical. Process control, as implemented by AppliTek, will significantly increase output, product quality, and decrease production hazards. Environmental compliance is another value-added benefit of the AppliTek technology.
The concept is simple enough but the reality of maintaining proper disinfectant residuals just isn`t always that easy. The water quality in your distribution system is constantly changing and constantly on the move. The disinfectant residual is up... now it`s down... hotspots here... no spots there... just like a game of disinfectant "whack-a-mole".
The purpose of fast determination of hydrogen in wet chlorine is to set up an early warning system against high hydrogen levels, thereby protecting the chlorine production plant against hydrogen explosion incidents. The hydrogen concentration in wet chlorine is very critical, especially for membrane and diaphragm cell type production of chlorine. A breakthrough of hydrogen in the chlorine by membrane or diaphragm damage can occur within a few seconds. Depending on the concentration, a mixture of H2 and Cl2 gas...

Fast determination of hydrogen in dry chlorine provides an early warning system against elevated levels of hydrogen, thereby protecting the chlorine production plant against hydrogen explosion incidents. AppliTek’s analyzer system for fast determination of hydrogen in dry chlorine can be considered as Best Available Technology (BAT). However, it can never replace a system for determination of hydrogen in wet chlorine since it meets other needs in process control than those for wet chlorine. Even a tiny...
The purpose of fast determination of oxygen in wet chlorine is twofold: verification and control of membrane oxygen permeation, as well as to keep control of the oxygen-chlorine-ethylene explosion triangle. The technology behind AppliTek’s analyzer system for the fast determination of oxygen in wet chlorine is qualified as Best Available Technology (BAT) as defined by US Clean Air Act and Clean Water Act, as well as European directive 96/61/EC.
The purpose of fast determination of oxygen in dry chlorine is to verify the chlorine oxygen specifications, as well as to keep control of the oxygen-chlorine-ethylene explosion triangle. The technology behind AppliTek’s analyzer system for the fast determination of oxygen in wet chlorine is qualified as Best Available Technology (BAT) as defined by US Clean Air Act and Clean Water Act, as well as European directive 96/61/EC.
Wood treatment used to protect lumber from fungi, insects, UV damage, water damage and general wear. When treating wood the proper balance of treatment solution must be monitored to ensure the highest quality while minimizing waste and excess cost due to treatment usage or product rejection.
Levels of oxygen in dry chlorine in hydrochloric acid synthesis are monitored by means of an on-line analyzer system that can be equipped with two different measuring technologies: Alternating Pressure Paramagnetic or Tunable Diode Laser (TDL) analyzer system.
