Good sample preparation is an essential part of obtaining accurate analytical results, no less so in the preparation of fused beads: the choice of the correct quality flux, the method and the equipment for producing the bead. Accurate temperature adjustment and control, including the correct cooling regime, are crucial to making quality, reproducible fused beads.

The Vulcan can rapidly change fusion temperatures to suit different material types. Consequently, and unlike electronically heated furnace type devices, switching from a high temperature fusion routine to a lower temperature routine, does not result in significant operational time loss. This is a great advantage for a busy laboratory that is tasked with preparing a wide range of material types for XRF analysis.

The Vulcan addresses all the control issues and proves second to none in Automatic Bead Fusion, providing:

Accurate flame control for optimum fusion conditions, using gas, air and oxygen mixes

• Repeatable and stable fusion temperatures with no variation due to ambient conditions
• Low burner temperatures for sample oxidation and no upper temperature constraints, reducing the need for complex flux mixes
• Programmable gas control for multiple temperature settings including temperature ramping during fusion gives system flexibility when a wide range of samples types need to be fused (Optional)

Separate burners and cooling control for casting dishes

• Correct temperature of casting dish allows good bead formation
• Control of cooling conditions improves bead release and reduces the need for release additives
• Correct flame timing maintains good condition of platinum ware

Flexibility and programmability

• All functions have an override capability to allow manual control of the fusion process, for safety and during method development
• Fusion programs and advice available for special applications such as ferro alloys. Fusion settings can be stored in memory as application programs, allowing accurate, repeatable control of the fusion process

The Vulcan can also be used to directly prepare solutions for ICP/AAS or a combination of beads and solutions.
