MetCam: Methane Optical Gas Imager - CI Systems
A CI experiment involves the use of gas phase acid-base reactions in the chamber. Some common reagent gases include: methane, ammonia, water and isobutane. Inside the ion source, the reagent gas is present in large excess compared to the analyte. Electrons entering the source will mainly ionize the … Meer weergeven Chemical ionization (CI) is a soft ionization technique used in mass spectrometry. This was first introduced by Burnaby Munson and Frank H. Field in 1966. This technique is a branch of gaseous ion-molecule chemistry. … Meer weergeven The chemical ionization process generally imparts less energy to an analyte molecule than does electron impact (EI) ionization, resulting in less fragmentation and usually a simpler spectrum. The amount of fragmentation, and therefore the amount of structural … Meer weergeven One of the main advantages of CI over EI is the reduced fragmentation as noted above, which for more fragile molecules, results in a peak in the mass spectrum indicative of … Meer weergeven Negative chemical ionization Chemical ionization for gas phase analysis is either positive or negative. Almost all neutral analytes can form positive ions through the … Meer weergeven The CI source design for a mass spectrometer is very similar to that of the EI source. To facilitate the reactions between the ions and molecules, the chamber is kept relatively gas tight at a pressure of about 1 torr. Electrons are produced … Meer weergeven CI mass spectrometry is a useful tool in structure elucidation of organic compounds. This is possible with CI, because formation of [M+1] eliminates a stable … Meer weergeven • Proton-transfer-reaction mass spectrometry • Electrospray ionization Meer weergeven WebENERSENSE INTERNATIONAL OYJ : Vorstellung des Unternehmens ENERSENSE INTERNATIONAL OYJ, Aktionäre, Vorstände und Berufsbeschreibung, Finanzstärkerating, offizielle Mitteilungen, Kontaktdaten und Börsenkennzahlen … olympics drug selling
