Knowledge of gas detection

Here you will find our knowledge in PDF format

Gas alarms and gas detectors must be selected, installed, configured and maintained correctly, for the best possible and safe result. On this page we have gathered some of our knowledge about gas detection. GasDetect is always ready to advise on the right choice of gas detectors or hand-held gas alarms, so that they best suit your task

What is PID?

PID is an abbreviation for “Photo-Ionization Detector”. A PID is a hand-held, person-worn or wall-mounted detector that measures a wide range of Volatile Organic Compounds (VOCs) and displays organic components on a scale from parts-per-million (ppm) to parts-per-billion (ppb ). The VOCs give a continuous result and can alarm when the levels exceed the user-defined limit values.

A guide to gases

Pharmaceutical and bioanalytical laboratories.

There are many different gases inside a pharmaceutical or bioanalytical laboratory. Many have no taste, color or smell, which makes it difficult to know that there is a gas leak. A gas leak from a cylinder or a fixed piping system used to carry gas poses a serious risk that can cause potentially fatal incidents or hazards in a laboratory environment.

White paper on “visual alarms”

EN 54-23, which will be mandatory from the beginning of March 2013, was developed as a supplement to EN54-3 for acoustic alarm equipment; the break-in period already ended in 2005, which means that it is now the current technological state.

Why bump tests can save lives

Article about how bump testing of gas alarms, before use, can ultimately save lives. Based on data from more than 27,000 gas alarms and 1100 customers (in English).

Chemical names for gases

List of the most common gases, their chemical names and chemical designations (CH4, NH3, CO, CO2, H2S, O2, SO2 + many more).

Cross sensitivity between gases

List of cross sensitivities between different gases when measured with a detector from Industrial Scientific Oldham. How different gases can affect the sensors.

LEL limits for gases

List of LEL limits (Lower Explosive Limit) for various gases (vapours). Used to correctly adjust alarm limits on gas alarms.

When to take Benzene seriously

“In people who are exposed to benzene, studies have shown a wide range of serious medical and physiological consequences, both acute and long-term, such as cancer and aplastic anaemia. Therefore, there is a need to reduce exposure to benzene, both for people who work with it but also for the general population.” – World Health Organization.

In the article ‘The Basic of Bezenen – Properties : Exposure : Detection (English language versions) Benzene is considered. Here you are introduced to the basic knowledge of what is benzene? Here you are introduced to the basic knowledge of what is benzene?
