FieldMaster™ Resistive Glass is a patented process that uses lead silicate to create a resistive layer at the surface. When such glass is used in Capillary Inlet Tubes, the surface acts as a semiconductor as the resistive properties create uniform electric fields.


Voltage is applied across the tube preferentially attracting either positive or negative ions, more effectively drawing them into a mass spectrometer. These electric fields can guide or direct charged particles, improving ion transmission in atmospheric pressure ionization applications.

 

Resistive Glass prevents ion collisions between other ions as well as the tube walls, reducing ion loss and boosting sample transfer efficiency.  Polarity switching can occur at a much higher rate, which boosts the efficiency of the analysis.  Additionally, the electric field can be varied across several orders of magnitude.  Capillary inlet tubes made from Resistive Glass increase transfer efficiency when compared to traditional quartz tubes.

 

FieldMaster™ Resistive Glass Capillary Inlet Tubes are available in both a Single Channel and as a MultiCapillary Array, which has six distinct channels contained within a single inlet tube.  The single capillary array resistive glass increases transfer efficiency between 6 and 10x when compared to traditional quartz tubes, while the multicapillary array can increase efficiency up to 1000x using the same comparison.

Tubes can be ordered by standard ID and OD specifications in standard lengths to fit most mass spectrometers.
