Our atmosphere is dynamic. Biological, physical and chemical processes contribute to ‘clean air’, a gas mix which is remarkably well balanced for life and free of toxic gases and particulates.

Oxygen is at as high a concentration as enables aerobic organisms such as us to breath easily, whilst not so high as to cause unquenchable forest fires. Carbon dioxide is plentiful enough for plants to grow, both as a source of carbon and in retaining sufficient but not too much warmth from the sun. Elements essential for life such as sulfur and iodine are transported from land to sea in the form of volatile organic compounds (VOCs).

Many gases, which are toxic or harmful to life are removed by chemical and physical adsorption on solid particles (particulates) which ultimately fall out of the air under gravity as dust or rain. What is more, through a series of chemical reactions, including reactions with sunlight (photochemical reactions), the atmosphere is kept almost completely free of specific VOCs released by plants, it would seem to their own and wider advantage. For example, it has been recently established that on being bruised, leaves release VOC messengers (pheromones) that attract predators of leaf eating insects! Read more! 

Leak checks to analytical laboratory equipment promotes good laboratory practice and preventative maintenance offering a number of benefits including; improvements to analytical performance, minimising troubleshooting, and the prevention of damage to columns and sensitive detectors. Gas leaks can cause significant losses of expensive high-quality gas, shortened trap and purifier lifetimes, increased column bleed, and increased system and detector maintenance. Many problems can be minimised by leak checking a complete analytical system.

Pharmaceutical and biotechnological companies use gases in a wide range of applications across all stages of the production chain – from research, development and quality control to production of active pharmaceutical ingredients (APIs) and final drugs. Industrial gases are essential to the development of modern medicines and the production of pharmaceutical packaging.

There are a wide variety of gases found within a pharmaceutical or medical laboratory. Many have no taste, colour or smell, which makes it difficult to tell if a gas leak is present. A gas leak from a cylinder or fixed pipe gas system poses a series risk that can cause a potentially fatal incident or hazard within a laboratory environment.

The pharmaceutical industry is one of the worlds fastest growing industries. Most of the sales revenue it generates is then reinvested in the area of research and development of new products. Research and development uses a wide range of speciality gases and equipment. Analytic instruments such as gas chromatographs, liquid chromatographs and spectrometers all rely on the appropriate level of gas delivery to operate effectively.

Market-leading hand-held PIDs part of vital equipment on board government body’s ‘first responder’ reconnaissance vehicles.

Ion Science has recently supplied 300 Tiger hand-held volatile organic compound (VOC) detectors to Germany’s Federal Office of Civil Protection and Disaster Assistance (BBK) where they are part of the vital chemical measurement system on board ‘first responder’ reconnaissance vehicles.

An emergency response organisation will greatly increase its effectiveness and the level of protection it offers its employees (Responders) by deploying a photoionisation detector (PID).

Incidents Involving VOCs
Many Hazardous Materials incidents involve volatile organic compounds (VOCs), a vast chemical family that is primarily made up of hydrocarbons such as gasoline, alcohols, methane and acetone as well as the BTEX family which include benzene, toluene, ethylbenzene and xylene. Typically, VOCs have a high vapour pressure at ambient temperatures, meaning the liquid gives off vapour that can be readily detected.

Hazardous Material spills including biological, chemical and radiological materials pose a serious risk if not promptly and properly responded to by the individuals who initially identify the spill and the appropriate emergency response team.

When a Hazardous Materials (HAZMAT) response team arrives at the scene of any incident or accident involving hazardous materials there are many unknown factors which initially need to be identified, so it is critical that First Responders tackle each incident in an accurate and systematic way.

The versatile nature of a PID instrument makes it an indispensable device for the emergency services in response to a HAZMAT incident.

The ability of a photoionisation detector (PID) to measure low levels of volatile organic compounds (VOCs) makes them a vital tool in the decision making process following a hazardous materials (HAZMAT) incident. In the immediate aftermath of an accident, chemical spill or other incident involving hazardous materials there are many unknown factors. The speed at which these can be identified is key to the response, containment and clean-up effort. In the event that the HAZMAT materials are VOCs the sensitivity of photoionisation detection to measure low (parts per million - ppm) levels that can be toxic but not detectable by standard lower explosive limit (LEL) sensors make it a versatile tool for evaluating the dangers in an emergency response situation.
