Non Thermal Plasma Method to Prepare [11C] Methyl Iodide From [11C] Methane and Iodine Methane and Iodine

A kit used for preparing a method for producing [11C]methyl iodide, wherein the method comprises the steps of:

• obtaining methane (A1) from the reduction of carbon dioxide with nickel
• and then adding a cyclotron to produce [11C] onto the methane target whereby the [11C]methane is carried into said system in a stream of a carrier gas whereby a carbon dioxide trap (A2), a drying tower (A2 and A4), and a hydrogen trap (A3) are used to remove hydrogen;
• introducing a mass flow regulator (A5) to mark the start of the low pressure area of said system whereby the low pressure area contains an iodine source (A6), a plasma reactor (A7), and a trapping chamber (A8) and wherein the mass flow regulator is regulated by a pump (A10);
• transferring [11C]methane via said iodine source into said plasma reactor, whereby iodine vapors form and pass through said system simulataneously simultaneously with [11C]
• methane to further form a gas stream;
• applying a voltage to electrodes positioned in said gas stream inside said system, whereby electrons are stripped from the carrier gas and plasma is created thus forming a [11C]methyl iodide plasma, and then
• transferring said [11C]methyl iodide plasma via said trapping chamber and said pump
• to a reaction vial (A11) containing a suitable solvent or a loop reaction system.
