An evaluation instrument, pertaining to the system, comprises a storage container, where a plurality of test elements is held ready for use, a sample application position, where one test element at a time is brought into contact with the sample, a measuring device for the determination of a measurable variable characteristic for the analysis, and a transport device, by which one test element ...

An air filter apparatus, in particular for a heating and/or air conditioning installation for a motor vehicle, is of the kind comprising a housing through which an air stream can pass, with at least one filter member pivotally mounted within the housing for movement between a working position and retracted position. The filter member comprises a first end which is pivotally mounted about a first axis extending at right angles to the direction of flow of the air stream, and a second end disposed ...

A dust collector includes a base, a cover, and a barrel disposed between the base and the cover. The barrel includes a lower frame, an upper frame, one or more intermediate frames, and one or more telescopic tubes selectively secured to the frames, to form a spatial structure for the barrel, and the barrel is collapsible to a collapsed structure when the telescopic tube is disengaged from the lower and the upper and the intermediate frames. The intermediate frames may be received within the uppe...

A droplet separator including a plurality of droplet separating members configured for the formation of packs which are disposed at a supporting structure. The packs are connected to the supporting structure in an upwardly tiltable manner. Accordingly, the droplet separator can be inspected and manually cleaned in a simple manner even with closest space conditions.

A flue gas purification system comprising in the flue gas stream an electrostatic precipitator, mercury sorbent injection and a two-stage electrostatic separator, and wherein the mercury sorbent injection is positioned between the electrostatic precipitator and the two-stage electrostatic separator.

Apparatus and process for extracting powder from a stream of powder laden air drawn from a manual powder spray booth in a first embodiment, with a cyclone recovery system, typically containing two cyclone separators for separating the powder from the air. The cyclone separators have a breakaway design to facilitate cleaning. The resulting cyclone cleaned air is drawn through a prefilter section by a fan section having serially stacked fans. The prefilter section further separates powder from the...

A method for detecting the presence and amount of carbon monoxide, comprising the use of infrared spectroscopy to compare the spectra of the test gas containing carbon monoxide and the reference gas. The reference gas is the test gas from which carbon monoxide had been removed by conversion using catalysts. The presence and quantity of carbon monoxide is determined by deducting the spectrum of the reference gas from the spectrum of the test gas. The catalysts comprise nanoparticles of gold preci...

Reagents for determining presence or concentration of cyanuric acid are described. The reagents include an indicator, a 2,4-diamino-6-alkyl-1,3,5-triazine, and may include a stabilizer, an antioxidant, or both.

Compositions for CO.sub.2 detector solutions and rapid-response reversible dry surface CO.sub.2 detectors made from them are disclosed. The CO.sub.2 detector solutions generally comprise a poly(oxyethylene) based compound, a pH sensitive indicator dye, an organic solvent, a cationic phase transfer agent and an anionic base. However, minimally these detector solutions comprise a poly(oxyethylene) based compound, a pH sensitive indicating dye, an organic solvent and a base. The solutions were embe...
