PHOTONIS Technologies SAS
Resistive Glass Tubes for Mass Spectrometers Resistive Glass tubes are made from a patented process that makes the surface a semiconductor. The voltage applied across the tube creates an electric field that preferentially attracts ions - either positive or negative - and more efficiently draws them into the mass spectrometer. The resisitive glass properties also prevents collisions with the tube walls and with other ions, resulting in a better sample transfer. Resistive glass capillary tubes are available in a number of sizes and lengths... (read more)
