2. APPLICATION

The Bulk industry

Chromatotec’s innovative solutions for the Bulk industry. Our advanced analyzers and monitoring systems ensure precision, efficiency, and safety in bulk handling and processing.

The U.H.P. industry

Companies like Air Liquide, Praxair, Air Products, and others in the petrochemical and chemical industry rely on Chromatotec for impurity control in gases delivered to customers. Chromatotec offers the airmoQuality system, comprising a 19″ rack cabinet with an industrial computer, calibration unit, and one to three analyzers to measure various components, including pure gases, sulfur compounds, CO, CO2, VOCs, CH4, NH3, Amines, and permanent gases at different concentration levels, ensuring gas quality for customers in the industry.

The Specialties industry

Chromatotec offers specialized solutions for the Specialties industry. Our products ensure precise control of VOC in nitrogen or helium, calibration cylinder usage, and detection of Mercaptans compounds down to 1 ppb. We also provide options for ppt analysis (30 to 3000 ppt).

The medical industry

offer solutions for impurity control in air, O2, or N2O. Our technology also addresses the detection of key substances such as Formaldehyde, ETO (Ethylene Oxide), and CO (Carbon Monoxide). Count on Chromatotec for precise and reliable analysis to maintain the highest standards of safety and quality in the medical field.

Food and Beverage Industry

Carbon dioxide (CO2) is a commonly used additive in food and beverage industry (e.g. for soft drink, brewery, and champagne carbonation). Its fabrication process can lead to the presence of impurities such as aromatics, BTEX, ammonia, acetaldehyde, Total Hydrocarbons and sulfur compounds (Total Sulfur Content, SO2, COS, mercaptans…).

To ensure people’s safety, limit values of these impurities has been set by various health and safety regulations. The International Society of Beverage Technologists (ISBT) CO2 Guidelines offers a list of parameters including the molecules listed above and its recommended limit (Table 1).

Gas Chromatography (GC) is one of the most commonly used techniques for CO2 quality and purity monitoring to ensure meeting legal requirements. Chromatotec® has developed a GC analytical system for impurities measurement in CO2.

Moisture monitoring in Chlorine and corrosive gases

Monitoring moisture in chlorine and corrosive gases is crucial because even small moisture concentrations make chlorine highly corrosive. In chlorine production, online moisture measurements are recommended before compression and liquefaction to prevent corrosion. The chlorine DET H2O system, based on electrolytic analysis, measures water traces in chlorine, featuring controls for pressure, flow, and inert gas purging. It’s designed for corrosive environments, with a programmable measurement range from 0-50 PPB to 1,000 PPM. The unit is typically installed in non-corrosive areas, and parameters can be adjusted via an integrated keyboard. Output options include a 4-20 mA analog signal or digital serial communication.

European Pharmacopoeia and medical gases

Continuous moisture monitoring in medical and pure gases, such as O2, is essential to meet European Pharmacopoeia standards. Medical air, comprising 22% oxygen and 78% nitrogen, requires moisture levels below 67ppmV for it to be “breathable.” The DET H2O moisture monitor employs electrochemical measurement, offering precise values within a range of 0.5ppmV and even down to ppb, tailored to specific needs.
