FieldMaster resistive glass capillary inlet tubes use lead silicate to create a resistive layer, which controls the speed and direction of ions. The tubes are available in single-channel and multicapillary array configurations. 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.

PRESS RELEASE

PHOTONIS USA Adds Capillary Inlet Tubes to its FieldMaster™ Resistive Glass Line

Sturbridge, MA - PHOTONIS USA, a leading electro-optic manufacturer, announces a new line of Capillary Inlet Tubes, manufactured with FieldMaster™ resistive glass. The new inlet tubes are designed to control the speed and direction of ions, resulting in a significant increase in transfer efficiency when compared to quartz inlet tubes.

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.

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.

FieldMaster™ Resistive Glass products can be ordered in a range of standard sizes and with custom resistance to suit the application. The resistance can be varied over many orders of magnitude. Resistive glass products can be used as ion guides, drift tubes, inlet tubes, and reflectron lenses. They can be easily cleaned without degredation of performance. They will be featured at PHOTONIS’ booth at Pittcon (#1227) in Atlanta GA on March 14-17, 2011.

PHOTONIS is a multinational high-technology group, with more than 40 years experience in manufacture, sales and innovation, specializing in photo sensor technology. The Group operates Internationally in the Night Vision, Industrial, Scientific and Medical Imaging markets. PHOTONIS USA designs and manufactures a wide range of custom and standard components and assemblies for mass spectroscopy as well as other medical, bio-medical and scientific instruments and holds several patents in these fields.
