Detection of unknown substances by means of Dräger detector tubes*
Detection of various organic and some inorganic substances:
Polytest
e.g., Acetone
Acetylene
Ammonia (at > 1 vol.%)
Arsenic hydride
Gasoline (engine fuels)
Benzene
Ethylene
Liquid gases
(propane, butane)
Carbon monoxide, Monostyrene
positive
Perchloroethylene
Carbon disulfide
Hydrogen sulfide
Municipal gas (with more than 2 vol.% of CO)
Nitrogen monoxide (NO)
Toluene, xylene, trichloroethylene
positive
negative
Detection of various organic substances:
Detection of some
halogenated hydrocarbons:
Detection of amines:
Ethyl acetate 200/a
Perchloroethylene 2/a
Ammonia 0.25/a
e.g.,esters of acetic acid, alcohols, ketones, benzene
toluene, benzine hydrocarbons
positive
e.g.,perchloroethylene UN N° 1897
(chloroform, dichloroethylene,
dichloroethane, >50 ppm methylene
chloride, trichloroethylene)
e.g.,triethylamine UN N° 1296
(ethylene diamine,
hydrazine, ammonia)
negative
Detection of important
aromatic hydrocarbons:
Detection of
propane butane:
Detection of acidreacting substances
Toluene 5/b
Hydrocarbon 0.1%/c
Acid Test
e.g., benzene, toluene, xylene
and ethylbenzene
e.g.,propane UN N° 1978
Detection of ketones:
Detection of CO:
Acetone 100/b
Carbon monoxide 10/b
e.g.,acetone UN N° 1090
methylisobutyl ketone,
methylethyl ketone
Detection of alcohols:
Alcohol 100/a
e.g., formic acid, acetic acid,
hydrochloric acid, nitric acid
Further detection
e.g.,methane, ethane, H2, CO2 and other
substances may be necessary
e.g.,CO UN N° 1016
Further detection
of other substances may be
necessary
e.g.,alcohol UN N° 1096
butanol, methanol, propanol
*Important: This sample taking schedule refers to a selection of substances which frequently occur in practice. Other situations
may necessitate another sequence of measurements. If this is the case, the use of additional detector tubes,
procedures or measurements must be completed.
