Application Spotlight
Advantages of Glass Expansion RF Coils:
• High purity and consistent plating promote extended coil life
• Each coil is supplied on a plastic former ensuring correct
dimensions are maintained and allowing easier installation. These
formers can be then used periodically to check the coil dimensions,
so it is a good idea to keep the former even after coil installation.
• Each coil is supplied in a special protective container to ensure
correct dimensions are maintained, and the coil arrives corrosion
free.
• Correct alignment of the coil with respect to the torch body
reduces devitrification of the outer tube and ensures the plasma
is concentric within the torch allowing the sample aerosol to travel
correctly through the plasma.
In addition to producing the highest quality RF coils, Glass Expansion
also simplifies the installation with a “Do-it-yourself” RF coil installation
kit. Each kit is designed specific to the ICP model, including an
installation tool, spanner and easy to follow step-by-step graphic
instructional CD (Figure 4). This way you ensure proper alignment
and concentricity each and every time, in addition to saving the cost
of a service call and minimizing ICP downtime. Glass Expansion
has recently added to its family of RF coils to accommodate more
models of ICP-OES and ICP-MS instruments. To view the complete
list, please visit our RF Coil web page.
