FMC sells chemical products used by beef and poultry processors to reduce pathogens, such as E. coli and salmonella, on uncooked beef and poultry. [13] FMC obtained a patent on a method for sanitizing fowl that have been killed, plucked and eviscerated by contacting the fowl with an aqueous acid solution and maintaining that contact for a time ...
Diamond Alkali Company was an American chemical company incorporated in 1910 in West Virginia by a group of glass industry businessmen from Pittsburgh. The company soon established a large chemical plant at Fairport Harbor, Ohio, which would operate for over sixty years. In 1947, the headquarters of the company was moved from Pittsburgh to ...
High-pressure chemistry is concerned with those chemical processes that are carried out under high pressure – pressures in the thousands of bars (100 kPa) or higher.High-pressure processes are generally faster and have a higher conversion efficiency than processes at ambient pressure.
Atmospheric pressure chemical ionization chamber cross section. Atmospheric pressure chemical ionization (APCI) is an ionization method used in mass spectrometry which utilizes gas-phase ion-molecule reactions at atmospheric pressure (10 5 Pa), [1] [2] commonly coupled with high-performance liquid chromatography (HPLC).

Chemical ionization in an atmospheric pressure electric discharge is called atmospheric pressure chemical ionization (APCI), which usually uses water as the reagent gas. An APCI source is composed of a liquid chromatography outlet, nebulizing the eluent, a heated vaporizer tube, a corona discharge needle and a pinhole entrance to 10 −3 torr ...
The erosion diameter of the spray spot formed by DESI is known to be directly tied to the spatial resolution. Both the chemical composition and the texture of the surface will also affect the ionization process. The nebulizing gas used most commonly is N 2 set at a typical pressure of 160 psi.
