Bulk samples such as metal blocks, ceramic sintered bodies, or pharmaceutical tablets are aggregates of microcrystals that can be measured by X-ray powder diffraction. With Rigaku’s bulk sample holder, thick bulk samples can be placed in a diffractometer with no need to cut or pulverize, enabling identification of crystal phases of bulk surfaces in a non-destructive manner. This application note shows the bulk analysis of brake pads.

It is only in the last two decades that Raman spectroscopy has begun to realize its potential as an almost universally applicable analytical technique from materials and life sciences applications to point-of-care analysis. This is primarily thanks to the availability of compact laser sources, high-sensitivity cameras, and high-resolution compact spectrometers. In this application note, the use of a stable high-power NIR 785 nm laser is shown to be critical in achieving high time resolution and high signal-to-noise ratios while allowing for both fast and slow processes to be captured simultaneously.
