Cooled Needle Vaporizing Injector

This injector was designed specifically to overcome problems associated with the hot syringe needle. It comprises a standard vaporizing injector with a glass insert. Between the septum and the upper region of the heated part of the injector body (and inserted into the upper region of the insert) is a gas-cooled jacket of length accommodating the needle of a standard syringe - when the needle is inserted only a millimetre protrudes into the heated region of the injector. After injection the syringe is removed and the cooling gas turned off. The base of the cooling jacket then heats up so that material coming into contact with it might be vaporized. The technique should ensure minimization of discrimination caused by selective fractionation from the syringe needle. Published results seem to confirm that the technique gives highly precise quantitative results.
