Modification of a packed GC injector to a versatile capillary injector

A modification of a packed GC injector to a capillary injector is presented using a simple device which is connected to the GC column by an adsorption-free connector. It permits injections of large sample volumes up to 500 μl hexane solutions on normal 0.3 mm i.d. capillary columns. No special requirements for the stationary phase are necessary. Involatile residues remain inside the device which can be exchanged easily. High performance of separation and quantification is achieved.
