Specac have long been involved with presses and dies that we have supplied into the XRF analysis market for pressed pellet sample preparation; joining up with Nieka who are based in Canada is a natural extension and one we are proud to achieve. Nieka produce the Fusion Fluxer, a leading tool for preparing sample fusion beads for XRF analysis.
Both pressed pellets and fusion beads have an important role to play in X-ray Fluorescent Spectroscopy, offering mutual advantages and benefits.
What are the advantages of using a Nieka fusion fluxer for XRF?
- main components have been placed a safe distance from any risk of damage from accidental spillage
- the lowest gas pressures of any machine on the market, at only 0.5psi for propane and 0.3psi for natural gas
- no oxygen or compressed air
- 100 gas levels for superb heat control
- a patented temperature control system to avoid heat transfer and energy loss between heating positions
Two of today's processes mainly using fusion are ore & mineral mining and cement manufacturing, but they are by no means the only ones. The demands of quality compliance and materials performance today is such that ‘out-of-spec’ is very costly both in time and money. But the potential effect from failures within health and safety are significant.
The grading and determination of alloy components in steel can be used to bracket metals using the standard comparative technique that XRF is for elements such as Chromium, Manganese, Molybdenum and Nickel.
Aerospace alloys is an obvious choice where accuracy is of critical importance. Based on aluminium, with tungsten, titanium and Niobium being used in various trace amounts.
The extreme conditions of potentially sub-zero temperatures from standing to potentially high temperatures after engine start-up is another example, where 100% confidence is vital. But all this must be achieved with traceability.
One of the most difficult samples to fuse is chromium, often requiring significant additional oxygen. Yet despite the Nieka Fluxer not requiring compressed air or oxygen, chromium samples are processed with ease
With the final sample being in the form of a glass disc, the original sample for analysis is effectively ‘bonded’ and can be retained for long term storage, traceability and re-check, whenever needed for verification purposes.
Functionality of The Nieka Fusion Fluxer
The functionality of any instrument is on 2 threads – cost and performance. The fact that the G4 requires no oxygen or compressed air and operates on the lowest gas pressure of any machine on the market is testament, but low cost is still a waste of money without performance.
The G4 has its own self-monitoring and check system that can be recorded over a network not only to offer repeatability, but assurance of perfect and consistent results every time, with full ISO 17025 traceability
The gas system has 100 levels of control for precise temperature control in the most demanding of environments, aided by the patented shield system to reduce radiant heat losses and prevent heat transfer between positions
Many machines have a single speed single direction rotation; Nieka by its modern design and capability can offers multidirectional and multi-speed mixing.
In the critical step of sample preparation for analytical constancy and repeatability is available at a level not previously achievable.
