An Orsat gas analyser or Orsat apparatus is a piece of laboratory equipment used to analyse a gas sample (typically fossil fuel flue gas) for its oxygen, carbon monoxide and carbon dioxide content. Although largely replaced by instrumental techniques, the Orsat remains a reliable method of measurement and is relatively simple to use. [1]
a mineral acid with many industrial uses; commonly used in the laboratory preparation of hydrogen halides Phosphorus pentachloride: one of the most important phosphorus chlorides; a chlorinating reagent. Also used as a dehydrating agent for oximes which turn them into nitriles. Phosphorus tribromide: used for the conversion of alcohols to alkyl ...
When the reagents are highly susceptible to oxidation, traces of oxygen may pose a problem. Then, for the removal of oxygen below the ppm level, the inert gas needs to be purified by passing it through a deoxygenation catalyst. [4] This is usually a column of copper(I) or manganese(II) oxide, which reacts with oxygen traces present in the inert ...
[1] This table displays the steps involved in using a GasPak to create a completely anaerobic environment for incubating an inoculated agar plate. After inoculating the agar plate(s) with bacteria under aseptic conditions, the agar plates are placed in an anaerobic jar that contains components, like the catalyst chamber, that will help facilitate the reaction to eliminate free oxygen and ...
production of anaerobic conditions for organisms that die in the presence of even little oxygen (anaerobiosis), e.g. tetanus bacteria Microscope: to observe microscopic specimens that cannot be seen by the naked eye. Microtitre plates: mostly used for ELISA: Microtome: cuts prepared specimens for analysis under microscope Nichrome wire loop
Kipp's apparatus, also called a Kipp generator, is an apparatus designed for preparation of small volumes of gases. It was invented around 1844 by the Dutch pharmacist Petrus Jacobus Kipp and widely used in chemical laboratories and for demonstrations in schools into the second half of the 20th century.
An ordinary glovebox, showing the two gloves for manipulation, with airlock on the right. The most straightforward type of air-free technique is the use of a glovebox.A "glove bag" uses the same idea, but is usually a poorer substitute because it is more difficult to purge, and less well sealed.
Potassium permanganate will decompose into potassium manganate, manganese dioxide and oxygen gas: 2 KMnO 4 → K 2 MnO 4 + MnO 2 + O 2. This reaction is a laboratory method to prepare oxygen, but produces samples of potassium manganate contaminated with MnO 2. The former is soluble and the latter is not.
