Workflow

streamlined particle analysis

Sample Preparation

Standard ø 47 mm patches were glued on special mounts in a 3 min operation. Keeping them straight and cross contamination free. Just flip in the sample into a position of the integrated 2 X sample changer. Click start.

Automated microscopy

Based on the measurement method the sample is illuminated to optimize contrast between substrate and particle. Autofocus operation ensures reproducibly sharp images.

Particle analysis

Individual particles are recognized using the most suitable threshold algorithms or your pre-set parameters and measured individually for their morphological parameters.

Target selection

Each particle image is stored together with the particles location.  Particles overlapping multiple fields of view are merged into one particle object.

Top interesting particles are recorded and photographed by higher power magnification and even 3D stacks with maximum focus depth to obtain optimum (X, Y and Z) spectroscopy locations. From this the height of a particle is measured.

 

Chmeical Identification

LIBS.ID

The so physically characterized particles are then measured by means of LIBS spectroscopy. The optimized spectra are immediately compared with pre-recorded spectra in a library to produce reliable matches.

Raman.ID 785

You can within the automated run apply Raman Spectroscopy to show the molecular structure of the particles material.

The results from the particles morphology as well as its elemental composition and molecular structure are combined to deliver a powerful picture especially helpful to transfer previously unknown particles into knowns.

All raw data are stored in a container that could be re-processed.

Compile great standard reports and combine morphology, color, size, chemical structure and elements to compelling information

 

Flexible imaging (microscopy)

In the fully software controlled automated microscope you control the software controlls illumination and the magnification for your specific measurement task.

Suitable illumination depends on the particles and the used substrate. For morphological directed Raman spectroscopy of particles the gold coated filt.AID filters are optimized. An optimized illumination for this sample is the dark field

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

Ultra fast image spectroscopy target acquisition

The system gathers morphological particle and the particles location without any user interaction. The instrument scans the surface of your sample automatically for particles. Depending on the particle size you chose the right magnification, e.g. 5x (field of view: 1.9 mm) for particles >25 µm. Counting all the particles on your ø 47 mm sample takes then less than 7 minutes. The lower the magnification the larger is the field of view and the faster is the scanning. For spectroscopy a high N.A. value is essential to collect a maximum of light.

Fastest particle detection

This is why the system uses different objectives for scanning (particle recognition) and spectroscopy. So the SPE automatically applies the right objective for optimum signal and aligns the analysis laser with the particle. This transfer of the particle coordinates over different powers of magnification is truly ultra-fast image analysis directed spectroscopy.

The system gathers morphological information and the particles location without any user interaction. You choose the best out of 6 integrated auto-thresholding algorithms for your sample. Or you choose manual thresholding for the particle recognition.

 

  • Number, size

Particle Feret's diameter (longest dimension), particle circular equivalent diameter, stretched fiber length

  • 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. 3D stacking is also available.

  • Particle stitching over the entire sample

Particles overlapping multiple field of views are combined to single particles with no limitations. E.g. a particle could be as large as 47mm and it would be seen by the instrument as one. 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.

 

Robust Raman - raman.ID

Combines optical microscopy with a reliable automated structure spectroscopy and therefore delivers composition identification for 150 Mio. organic substances. raman.ID delivers fingerprint spectra of the energy of the vibrations of all molecules. Within 2-60 seconds you gather detailed information about the chemical structure of your sample. It delivers excellent information to make initially unknown organic and inorganic micro-particles well known. It even works in water so you can collect valuable information about particles in-situ by using a wet-cell for your investigation.

ID chemical structure with multiple raman.ID colors

Raman spectroscopy works with a laser. The laser color is variable. Depending on your sample you choose the right wavelength or a combination of more than one. Particle contamination works best with 785 nm laser minimizing fluorescence.

 

Fully integrated identification and interpretation

The systems comes with a library and a powerful software matching particle spectra to typical extrinsic contaminants. Within a couple of minutes you can record your own material and update your product related library. Integrated algorithms optimize (remove weak fluorescence background) and match the particles spectrum with the pre-recorded with Pearson´s algorithm combined with a supervised search strategy. With every spectrum the software tells you the quality of the match with the library spectrum and spectrum quality. You can setup your level of minimum quality for the spectrum and the matching. This makes anybody working with your method to an expert that can now reliably produce ID of materials down to the 1 µm level.

Micro LIBS.ID

SPE LIBS.ID combines optical microscopy with a very sensitive element analysis system. Within one second (single shot LIBS) it delivers fingerprints of chemical elements of your sample. Thus, you optain excellent information to make unknown inorganic and metal material samples known.

ID chemical elements from   to

Laser Induced Breakdown Spectroscopy, LIBS works excellent for the lighter elements from Hydrogen to Uranium. Alloys quantitative composition, e.g. Copper in Aluminum is detected down to 0.1 mass percent.

µ-drill and surface cleaner

The ablation from the LIBS process removes the top layers (3-10µm) of your sample within microseconds. This helps to measure through surface coatings or contaminations. You gain access to material beneath deeper layers of your sample.

One click identification and interpretation

Easy to use measurement methods provide a key to all tools of modern data analysis and automated particle classification (e.g. inclusions and impurities) into different material bins.

Highly intuitive software

From easy parameter setup you transform your method development into solid GMP proof measurement receipts for your measurement. Integrated you find pre and post processing of individual spectra or on the entire data from a whole measurement run on thousands of particles. This makes the tool perfect for R&D as well as for your routine quality operations.

For each particle the report shows at a glance:

 – spectrum as it was obtained by the system

 – the same spectrum after the integrated background   and fluorescence removal

 – the best database match according to your preferred matching algorithm e.g. Pearson´s
