X-ray fluorescence spectroscopy is the technique of preference for the analysis of additiveand trace elements in fresh lubricants. The main strengths of the technique are itsreproducibility, accuracy and ease of use.
For the calibration of an XRF spectrometer for blending control applications, highconcentrated single element concentrates are required. Most of the commercial availableorganic standards are 5000 ppm and do often contain another non-certified major element(i.e. Sulfur). Since recently we can offer a list of high concentrated single elementconcentrates.
These concentrates are stable for several years (the test period covers 4 years)and miscible with each other. Below you can find a table that lists our commercially availableconcentrates. The table lists the concentration of the major element, some physical data andthe presence of trace elements (72 elements, from Sodium (atomic number 11) up to Uranium(atomic number 92) are tested).
• Analyze a wide range of elements: Boron to Uranium (4kW WDXRF), Sodium to Uranium (CG EDXRF)
• PPB-level elemental detection limits
• Simple 3-step process: pipette, dry and analyze
• Easy-to-use EZ Analysis user interface
• Minimal hazardous waste
• Non-technical operation
• No routine recalibration
• No gases or acids
• No digestion
• No filtration
