FieldMaster™ Resistive Glass Ion Guides

Product Announcement from PHOTONIS Technologies SAS


FieldMaster™ Resistive Glass Ion Guides-Image

Ion Guides and Drift Tubes:

FieldMaster™ Resistive Glass Ion Guides and Drift Tubes have demonstrated an improvement in ion transmission when compared to conventional tubes. They can be easily removed or cleaned without degradation in performance. The single-piece, solid tube design provides containment for counter-flow gas, eliminating the need for an additional enclosure.

PHOTONIS has developed a series of specialty glass tubes which can be used by analytical instrument designers and manufactures to facilitate the movement of ion samples by providing a specific, even electric field strength. Our FieldMaster™ Ion Guides and Drift Tubes are composed of a proprietary lead silicate glass that has been doped to produce a resistive surface. These tubes can be etched or be equipped with leads to optimize current flow. The resistivity can be varied over several orders of magnitude.

FieldMaster™ Ion Guides and Drift Tubes can be ordered in standard sizes and can also be etched, or equipped with leads to optimize current flow. The resistivity can be varied over several orders of magnitude.


Capillary Inlet Tubes:

When Resistive 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 increases 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.

 

Monolithic Reflectron Lenses:

PHOTONIS has patented a process using Resistive Glass Tubes to produce non-linear gradient electrical resistance changes within the monolithic tube structure. This single piece unit can take the place of a multi-piece stacked ring assembly which simplifies the cleaning process.

Current reflectron-type TOF-MS instruments use complex multi-piece stacked ring assemblies which carry timeconsuming assembly and cleaning processes. They also require the use of a voltage divider in each layer to reverse ion direction.

 A reflectrion lens made with resistive glass provides a solid assembly replacement for a stacked ring assembly yet provides the same ability to alter ion flow, becoming a form-fit-function replacement for the multi-piece stacked ring assemblies. Additionally, the solid resistive glass piece provides for simpler cleaning and replacement.

The process can also be applied to create collision cells from Resistive Glass.

Ion Mobility Spectrometers:

PHOTONIS' patented Resistive Glass technology is a key element to achieving high resolving power in our Ion Mobility Spectrometers. Our products offer high resolving power, and can be customized for use with a variety of sources including DESI, DART®, Electrospray, Corona Discharge, Radiation and more.

PHOTONIS Ion Mobility Spectrometer (IMS) Analyzer is a complete integrated assembly for simplified IMS analysis that features high resolving power (64-150) in a compact design. The unit combines PHOTONIS’ patented Resistive Glass products with a new robust ion gate technology to create an IMS analyzer which improves resolution and simplifies serviceability.

Key components of the IMS Analyzer are made from Resistive Glass to replace conventional lens assemblies. In the new IMS Analyzer, the reaction and drift tubes are comprised of Resistive Glass, providing a solid piece construction that allows uniform counter flow of drift gas without the need for additional containment.

Resistive Glass is manufactured in a patented process by PHOTONIS that creates an electric field to guide or direct charged particles, resulting in greater ion throughput and sample transfer. The compact platform is designed to be scaled or customized to interface with a wide variety of instruments to simplify IMS analysis in applications where a narrow range of contaminants need to be quickly identified. Its unique design allows the user to quickly and inexpensively perform a simple IMS analysis and receive fast, accurate results even at room temperature sampling.

 

Other Specialty and Custom Glass Products:

Glass Capillary Arrays:

Glass Capillary Arrays consist of millions of precision glass capillary tubes fused together to produce a uniform and mechanically rigid structure. They can be used for sample filtration, collimation or as optical beam line splitters.

PHOTONIS Glass Capillary Arrays have exceptional thermal and chemical stability, and can be manufactured to withstand temperatures in excess of 450°C for use in harsh environments. It can be provided with a ground matte finish or a polished service. The input surface can also be blackened to minimize light scattering.

Solid border Glass Capillary Arrays are compatible with most existing Millipore or Nuclepore equipment, or fitted within a metal flange or mounted on glass tubing for high temperature or high pressure applications. Glass Capillary Arrays can be ordered at various bias angles and in a variety of shapes and sizes for your custom application. -

Flexible Fiber Optic Light Guides

Fiber Optic Light Guides offer unique solutions to long-standing design problems. They are well-suited to explosive, corrosive, high-voltage, radiation and other hazardous environments. Custom sheathing and end tips can be added to support your specific application.

PHOTONIS Flexible Fiber Optic Light Guides transmit light through glass optical fibers. These light guides collect light in a large acceptance angle, typically 82°, which is equivalent to a f/0.57 lens. Fiber Optic Light Guides can transport light over complicated paths into remote areas, saving weight, space and cost.

Glass Coated Wire:

PHOTONIS is the pioneer of glass coated wire technology. Originally designed to improve the electrical characteristics of ion-generating corona wires, glass coated wires today can be used in high-speed printing, high temperature sensing, corrosive atmosphere wiring, and electrostatic precipitation.

PHOTONIS manufactures its Glass Coated Wire using a state-of-the-art drawing process which creates a very smooth glass layer on the wire core. The glass is chemically bonded to the wire and hermetically sealed, protecting the wire from oxidation and chemical attack.

PHOTONIS is the pioneer of Glass Coated Wire technology, which was originally developed to improve the electrical characteristics of ion-generating corona wires in high speed copiers. An insulating layer of glass can be added to nearly any kind of metal wire by drawing the wire through a molten glass preform. All our Glass Coated Wire is custom-sized for your particular application, so contact PHOTONIS regarding your particular Glass Coated Wire needs.
