Single-bore

Significantly improve ion transfer efficiency compared to conventional quartz inlet tubes.

Voltage applied across the inlet tube creates an electric field that preferentially attracts ions into the inlet tube.

Forces more ions into the mass spectrometer.

Also prevents collisions with other ions and tube walls which can produce ion loss, resulting in more efficient sample transfer.

Resistive glass inlet tubes provide unique ability to preferentially attract + or – ions.

Rate of polarity switching can be accomplished more quickly with resistive glass tubes.
