摘要:
The invention relates to an electrochemical gas sensor (10) comprising a housing (20) and at least one electrode (21, 22), wherein the housing (20) comprises a gas inlet (23), wherein an at least strongly acidic, fluid electrolyte (30) is present in the gas sensor (10) and wherein the electrolyte (30) at least partially wets the electrode (21, 22). In a gas sensor (10) of this type the electrolyte (30) contains an additive, wherein the additive comprises at least one surfactant. The invention further relates to an electrolyte (30) for a gas sensor (10), which comprises at least one surfactant as an additive.

The invention relates to an electrochemical gas sensor (10) comprising a housing (11) which has a number of electrodes (31, 32), i.e. at least one working electrode (31) and at least one counter electrode (32), in additon to a liquid electrolyte (60), at least one of said electrodes (31, 32) and/or the housing (11) consisting at least partially of an absorption agent composition. The invention also relates to the use of a sensor of this type for detecting acid gases.
摘要:
A gas measurement system for measuring the concentration of gaseous and/or vaporous components of a gas mixture by means of the color change of at least one reaction substance on a reaction support unit in which the at least one reaction substance is arranged on the reaction support unit separately within at least two light permeable channels is provided in such a manner that data can be read out reliably at low technical expense. The data reading device can be designed as a digital camera and/or as a reading apparatus for an electronic data storage device.

Die Erfindung betrifft einen elektrochemischen Gassensor 10 mit einem Gehäuse 20 und wenigstens einer Elektrode 21, 22, wobei das Gehäuse 20 einen Gaseinlass 23 aufweist, wobei in dem Gassensor 10 ein wenigstens stark saurer, flüssiger Elektrolyt 30 vorhanden ist, und wobei der Elektrolyt 30 die Elektrode 21, 22 teilweise benetzt. Bei einem solchen Gassensor 10 ist vorgesehen, dass der Elektrolyt 30 einen Zusatz enthält, wobei der Zusatz wenigstens ein Tensid aufweist. Die Erfindung betrifft weiter einen Elektrolyten 30 für einen Gassensor 10, der als Zusatz wenigstens ein Tensid aufweist.
摘要:
The invention relates to an electrode (100) for an electrochemical gas sensor (1) wherein the electrode has a gas-permeable membrane, and wherein a graphene layer (3) is deposited on the gas-permeable membrane (4) as electrode material. An electrode (1) of this type is manufactured, for example, in that a dispersion of graphene or graphene oxide in a volatile liquid is applied onto a gas-permeable membrane and the volatile liquid is evaporated.
