Trace Evidence ID

Result with max confidence

The SPE-f raman.ID + metal.ID, using remarkable orthogonal spectroscopy analyses, can now identify unknown material, chemical elements, chemical structure, and organic/inorganic particles. In trace evidence ID locating the microparticles in the sample and apply microspectroscopy was often time consuming. Now you can use the imaging guided spectroscopy to obtain spectra only of the particles you are interested in. E.g. 10 µm sperically shaped gun shot residue particles or only 40-60 micrometer skin flakes. Documentation and interpretation is also integrated helping you with the ID of unknowns in minutes.

Produce results in a timely manner

Reliable imaging + spectroscopy combination - integrated imaging directed spectroscopy ensures the measurement of just the particles you are interested in.
High reproducability – no user interaction is required to run samples. All measurement parameters are set in receipt files.
Fast results – enumeration of a sample in just 5 minutes. Identification of 50-3000 individual contaminating particles per hour.
High sample throughput - load up to 2 samples into the system and run them fully automated.
Minimal user training - after 1-3 days of on site user training, anybody is able to work with the system.
Robust - integrated system with worldwide support.

ID of trace evidence materials

Image analysis -> particle number, size and shape

The system gathers morphological particles information without any user interaction. From each particle the system reports:

Number, size:
Feret's diameter (longest dimension)

Shape:
Aspect ratio; Angularity, rectangularity, elongation, area, perimeter, circularity, solidity, fibrosity, convexity and height

Particle color image:
Automatically collect and document high resolution sharp (auto-focus) color images of the particles.

Imaging led spectroscopy:
The coordinates for each particle are potential spectroscopy target locations. Select particles morphology for the identification.

With pre-defined methods illumination, auto-thresholding and auto-focus a complete user bias is established. This ensures high repeatability and reproducibility of the counting results.

raman.ID -> chemical structure

raman.ID gives fingerprint spectra of the vibrations of all molecules. With the integrated unique spectra interpretation you can quickly and reliably identify organic and inorganic particle materials by their spectra without specialized knowledge. The fingerprint spectra is extremely sensitive to the chemical structures to identify inorganic and organic materials.

Raman Spectroscopy delivers reliable spectra of the particles. It is non-destructive and virtually free of sample preparation.

Particle size and chemical distribution

Let the SPE raman.ID deliver results on hundreds of inorganic or organic particles in just a couple of minutes for you. Save years of laboratory time with imaging-led spectroscopy.

metal -> chemical elements

metal.ID gives spectra of the chemical elements. You can quickly and reliably identify inorganic and metallic materials by their spectroscopic fingerprints without specialized knowledge.

Particle size and chemical distribution

metal.ID is Laser Induced Breakdown Spectroscopy, LIBS. It is sensitive, ultra fast (1 s / Particle) and virtually free of sample preparation. It gives spectra of the several elements e.g.: Al, Au, Ag, Ba, Ca, Cr, Cu, Co, Fe, Li, Mn, Mg, Ni, Pb, Sn, Sr, Si, Sb, Ti, V, Zr, Zn as well as of hundreds of mixtures and alloys.
