Ethylene – C2H4

This page presents information about ethylene (C2H4) – or ethene, appropriate detection means – ethylene gas detector – and respiratory protective equipment (gas mask or PAPR with type A gas filters).

Ethylene gas detector and C2H4 respiratory protection

Ethylene properties

Ethylene (C2H4) – also known as ethene – is used for many applications in the chemical industry. It is the basis of petrochemistry, particularly for plastics production. Its derivatives – such as ethylene oxide or ethanol – are widely used in the pharmaceutical industry for their disinfectant properties. This gas is also used to stimulate and grow climacteric fruits (kiwis, bananas…).

Ethylene effects on health

Ethylene (C2H4) is a colorless gas hardly detectable through smell. Highly flammable, its explosive limits are set between 2.70 and 36% volume. At high concentrations, it may irritate the breathing system or cause dizziness. Even if ethylene is not toxic, it can transform into ethylene oxide in the human body, and this toxic substance is classified as carcinogenic by the IARC*.

Ethylene gas detector - C2H4

Hardly detectable through smell, only an ethylene gas detector can accurately measure concentrations of this gas. Moreover, as ethylene is a volatile organic compound with a 10.51 eV ionization potential, it is recommended to use a VOC photo-ionization lamp detector.

The colorimetric gas detection tube system is a simple and accurate solution composed by a manual sampling pump and a specific gas detection tube. They are designed for use together.

  • Gas detector tubes Colorimetric tube
  • Accurate: the sampling pump features a mechanical accuracy piston which creates a vacuum then enables direct reading on the colored tube (colorimetric tube)
  • Swift: one or two pump strokes are enough to draw sample and the value can be directly read on the tube
  • User-friendly: no knowledge, no specific process and no technical competence are required

VOC detector MX6 volatile organic compounds

The MX6-VOC accurately measures presence of volatile organic compounds (VOC) in ambient air using a 10.6 eV PID photoionization lamp from 0 to 2,000 ppm in 0.1 ppm increment.

  • User-friendly menu for easy access
  • Certifications: IECEx/ATEX : EEx ia d IIC T4
Additional information

Volatile organic compounds – most commonly known as VOCs - gather thousands of substances and gases. They can be found in many fields of activity. The MX6-VOC gas detector is a classic single-gas detector especially designed to detect these substances. Thanks to its ion-lithium rechargeable battery, it can operate during 12 hours according to the application.

The MX6-VOC gas detector needs to be calibrated twice a year in order to ensure proper operation. The photoionization sensor (sensor technology for VOC detection) can detect volatile organic compounds with a ionization potential below 10.6 eV. The MX6-VOC measuring range is set between 0 and 2,000 ppm in 0.1 ppm increment.

An integrated gas sampling pump guarantees measurements accuracy. This pump also enables to draw remote samples before intervention. According to the configuration, it is possible to add up to 5 more gases to the MX6-VOC.

This VOC detector features 3 different alarms. The powerful audible alarm is designed to alert even in noisy environments. The high visibility red LED visual alarm and a vibrating alarm are also made to ensure a high level of protection.

Its large colored screen displays concentrations in ppm (part per million) or in percentage volume. Digital values can be replaced visually thanks to the user-friendly menu.

The MX6-VOC gas detector is impact-resistant thanks to an over-molded polycarbonate housing. This monitor meets almost any EU current gas detection related standards.

The CUB is a portable VOC detector with photoionisation detection (PID) technology designed to quickly and accurately detect volatile organic compounds, keeping workers safe within working environment. With parts-per-billion (ppb) sensitivity, the CUB personal gas monitor gives an early warning of exposure to hazardous gases. Comfortable and unobtrusive to wear, the CUB can be easily worn close to the breathing zone thanks to its crocodile clip and is to date the smallest, lightest, personal VOC detector available.

CUB personal detector has a dynamic range of 0 to 5,000 ppm – the widest on the market – measuring 480 selectable compounds. When worker exposure exceeds pre-set limits, an audiovisual and vibrating alarms alert users on hazardous gases concentrations. Readings are displayed on a bright, backlit LCD display with selectable data logging time. Its long duration battery enables a continuous operation during 16 hours when fully charged.

CUB’s patented photoionisation detection (PID) sensor technology has been independently verified as best performing for speed, accuracy and humidity resistant operation. The PID sensor’s Fence Electrode features a humidity resistant and anti-contamination design providing extended run-time in the most challenging environments. Thanks to this technology, the CUB gas detector offers fast response to hazardous gases and vapors (less than 13 seconds).

The CUB personal VOC monitor is available as a standard instrument with 10.6 eV lamp for accurately detecting a wide range of volatile organic compounds (VOCs) in parts per million (ppm) levels. The CUBTAC ppm variant version with 10.0 eV lamp can accurately detect total aromatic compounds (TACs), including benzene. Both models can be quickly and easily upgraded with parts per billion (ppb) sensitivity.

This small and lightweight VOC portable detector is easy to use with a simple one button operation and an intuitive software. The instrument kit includes a charging docking station and calibration certificate.
