Low resolution Magnetic Resonance (NMR) and X-ray Fluorescence (XRF) has the widest variety of applications for analysis in chemical related applications.Measurement of hydrogen-bearing liquids in or on a solid background
Comparison of different phases of the same material within a single sample (for example, solid/liquid ratios)
In the general chemicals industry, a good example of the first type of measurement is the determination of oil content in sulphur powder, where the NMR signal from the oil can easily be measured without interference from the solid sulphur powder background.
There are a diverse range of materials requiring daily chemical analysis including; photocopier toners, aircraft sealants, flame retardants, polymers and resin. In many cases these materials are analysed using the well respected analytical technique of X-ray Fluorescence (XRF).
There are numerous benefits associated with analysing a sample using XRF including; minimal or no sample preparation, rapid non-destructive analysis, ease of use, operation by production staff, no potentially dangerous chemicals, ppm to high % concentration range, covering the periodic table range from Sodium to Uranium.
Where analysis involves a few elements the Lab-X3500 is the simplest, multi-element analyser typically measuring one to five elements. Samples types can be solid, liquid, powder, paste, film and are often measured “as received”. In some cases a simple grinding and pressing technique is required to produce a flat disc.
The X-Supreme8000 performs a similar task measuring additional elements and includes a 10 position sample carousel for unattended operation, and an integrated PC for storage of results. Samples are measured as above or fused into a glass bead for the highest accuracy. The MDX1000 is a simultaneous Wavelength Dispersive XRF instrument analysing multi-elements in the fastest possible time, with an optional 72 position auto-sampler.
In all cases the above analysers ensure reliable, robust, simple operation carried out on a 24/7 basis.
