Gas chromatograph equipped with a 63 Ni source electron capture detector. 5.3 Gaskromatograf utrustad med en electron capture-detektor med 63 Ni källa.

Ni-63 is of considerable interest and importance in radionuclidic metrology as well as for radiation protection surveillance around nuclear facilities.

Nickel-63 is used in the detection of explosives and in electronic devices like voltage regulators and surge protectors. Nickel-63 | Ni | CID 104905 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards The electron capture detector is used for detecting electron-absorbing components (high electronegativity) such as halogenated compounds in the output stream of a gas chromatograph.The ECD uses a radioactive beta particle (electron) emitter in conjunction with a so-called makeup gas flowing through the detector chamber. The electron emitter typically consists of a metal foil holding 10 1977-12-15 The radioactive nuclide 63Ni decays by a first-order process via the emission of a beta particle. The 63Ni nuclide has a half-life of 100. years. A 63Ni electron-capture gas chromatographic assay is described for buprenorphine, a potent narcotic agonist--antagonist. In addition, the assay is useful for the measurement of the metabolite norbuprenorphine and demethoxybuprenorphine, a rearrangement product resulting when buprenorphine is exposed to acid and heat.

63 Ni is electrically deposited on a rectangular or round nickel backing and covered with a protective nickel layer or corrosion-resistant layer.. Sources are characterized by ionization current measured in a flat free-air ionization chamber. Radius of a cylindrical source couldn’t be lower than L/2π, L — source length. Binding of 63Ni by cellular constituents in some tissues of mice after the administration of 63NiCl2 and 63Ni(CO)4. Oskarsson A, Tjälve H. One and 24 hours after the administration of 63NiCl2 and 63Ni(CO)4 to mice 63Ni was present in association with both particulate and soluble cellular constituents in the lung, liver and kidney.

Naturally occurring nickel (28 Ni) is composed of five stable isotopes; 58 Ni, 60 Ni, 61 Ni, 62 Ni and 64 Ni, with 58 Ni being the most abundant (68.077% natural abundance). 26 radioisotopes have been characterised with the most stable being 59 Description 63 Ni is electrically deposited on a rectangular or round nickel backing and covered with a protective nickel layer or corrosion-resistant layer. Sources are characterized by ionization current measured in a flat free-air ionization chamber. Radius of a cylindrical source couldn’t be lower than L/2π, L — source length. Ni-63 is of considerable interest and importance in radionuclidic metrology as well as for radiation protection surveillance around nuclear facilities.

Clin Chem. 1987 Jan;33(1):176-9. Improved 63Ni radiochemical assay of free fatty acids in plasma. Barash H, Akov S. We have modified the 63Ni radiochemical method of Ho (Anal Biochem 1970;36:105) for determination of free fatty acids (FFA) in plasma.

It is detected by using an Open Window Geiger-Muller Counter, NaI(Tl) Detector or Liquid Scintillation Counter (PerkinElmer, 2010). HOW IS IT USED? Nickel-63 is used in the detection of explosives and in electronic devices like voltage regulators and surge protectors. The radionuclide 63Ni (T1/2=100.1 a) has been proposed as a fluence monitor for fast neutrons in copper samples from Hiroshima.
