Draeger Tubes & Chip Measurement System Handbook

Draeger is the leader in industrial gas and vapor analysis and have developed more detection devices and tubes for more applications than any other gas detection company.

Draeger sampling tubes allow identification and measurement of different substances even under difficult conditions.

Draeger Chip Measurement System (CMS) combines Chips for measure specific substances with an electronic analyzer for easy-to-use spot-measurement. The analyzer combines an optical system for analyzing the color reaction with a mass flow controller and pump system.

List of Detectable Gasses and Vapors by CAS-Number

Leak detection Drager
As manufacturing processes advance, the use of flammable and toxic gasses is increasing, along with the probability of gas leaks. The potential for industrial plants, employees, and first responders to confront these situations is also increasing with potentially deadly consequences, namely explosions, asphyxiation, and loss of life.

A leak is an unpredictable abnormal release of gases or vapors of higher concentrations. A leak has to be regarded as an exceptional event of a relative short duration. In case of normal operation there is only clean air (without even low concentrations of the target gas or vapor). A gas detection system for leak detection is not to measure a gas concentration but to give alarm reliably if a preset alarm threshold is exceeded.

A key part of any safety plan is properly identifying what gasses are present, installing the proper early warning detectors, and defining a comprehensive safety plan.

The CAS-number is a worldwide used code to identify a chemical substance non-ambiguously. This is a unique numerical identifier issued to every chemical substance described in the open scientific literature (from 1957 to present) by the Chemical Abstracts Service. It the easiest way to characterize a chemical substance, including organic and inorganic compounds, minerals, isotopes, alloys and nonstructurable materials.

The guide below, provided by Drager, is a very helpful reference document of CAS-Numbers.

As with any critical process control or safety application, consultation with an applications expert is imperative prior to the selection or specification of any leak detection, gas monitoring, or safety device.
