Highest Contrast & Highest Throughput for Challenging Samples
The ChromaXRM features Sigray’s patented x-ray multi-color source. Selecting the x-ray color of the x-ray beam illuminating the sample can dramatically improve contrast to visualize details that would otherwise be missed, as clearly is seen in the images below comparing the ChromaXRM to the setup of the next leading XRM. Because of the high contrast, tomographies can be acquired at 10X the throughput for these challenging samples.
500nm Spatial Resolution
ChromaXRM achieves the highest spatial resolution available on the market at 500nm (0.5 µm).
Shown below are individual eggs resolved in the eggs sacks of a daphnia (water flea) specimen.
Multiple Fields of View with 5 Detectors
Up to 5 detector configuration options are available within the same system, enabling selection between multiple resolution and field-of-view settings analogous to a visible light microscope. Below is an example workflow in which detector modes are switched by software to zoom in on features of interest in an intact medicine container.
Patented Multi-Spectral Contrast X-ray Source
ChromaXRM’s patented x-ray source technology offers up to 5 user selectable X-ray target materials. Changing the X-ray target enables the user to optimize the X-ray spectrum for each application, thereby maximizing contrast and throughput.
Each of the 5 x-ray spectra has its own peak x-ray energy and wavelength, similar to the concept of “color” for visible light. For example, blue has a 450 nm wavelength while red has a 750 nm wavelength. Similarly, an x-ray source target made of Chromium will produce 2.3Å wavelength x-rays while a Copper target will produce 1.55Å wavelength x-rays.
Samples of different compositions and sizes are optimized when the illuminating x-ray is of the correct color. Contrast and throughput can be maximized by >10X. Other XRM and microCT products on the market only offer an x-ray source with a Tungsten target, which offers good penetration but poor contrast on many challenging samples.

Life Sciences: Unstained Soft Tissue
X-rays are generally considered too energetic for soft tissue imaging. With the multi-spectral x-ray source on the ChromaXRM, a Chromium target can be selected to provide high quality, cellular resolution imaging of unstained biological soft tissue. Shown is an unstained liver sample with details down to hepatocytes.
Carbon Fibers and Low Z Materials
Carbon composites such as carbon fiber reinforced polymers and carbon paper represent some of the most challenging materials for 3D x-ray microscopes to image. The ChromaXRM provides excellent contrast and resolution for these samples, which enable straightforward segmentation for quantification.
Microstructural imaging during process development is critical in minimizing time to market. ChromaXRM provides the ability to: quantify batch to batch variations in coating thickness, measure the distribution of API in formulation, and find cracks, voids and defects in tablets and pills. Choice of x-ray target in Sigray’s patented multi-spectral x-ray source improves contrast and throughput.
Entomology and Botany
Selection of lower x-ray energies on the ChromaXRM’s multi-spectral contrast source enables excellent contrast for imaging insects and plants for entomology and botany research.
