Choose the SPE unit that suits your needs! We have a a great deal of experience regarding contamination source detection, production process issues, as well as parts cleanliness testing for the automotive industry.
The speed and flexibility of the SPE units also ensure smooth operation; with fast and reliable results.
Sample Preparation
Sample Preparation Typically particles are impacted on a surface from an airstream, glued to a tape, or filtered from a liquid. For filtration you can use any standard filter such as cellulose nitrate 25 mm or 47 mm filter patches and a similar type of membranes. On those membranes the SPE easily counts and identifies inorganic particles with metal.ID > 5 µm . Identification of organic particles such as fibres with raman.ID is limited to particles larger than > 25 µm in each dimension. They effectively shield the Raman laser focus from the filter material. To identify particles as small as 5 µm with imaging led Raman spectroscopy we suggest the use of the dedicated gold coated filtr.AID membranes. Adhesive tapes that are typically used in forensic investigations can also be mounted directly in the instrument.
Particle Counter
SPE-i CSS measures the number, shape, and size of particles ranging from1-40000 µm on filter membranes. This device provides reproducable results using fully automated image acquisition and analysis/documentation units. The particles appearing on the filters are used to evaluate the components' cleanliness levels according to ISO 16232 standards or other customized standards.
SPE-i metal.ID is able to sort particles 20 µm and greater, determine basic material/chemical composition(metal, non-metal, fiber), determine elements, recognize 100 alloys and much more. This particular tool can identify the elemental distibution at a throughput rate of 300 - 1000 particles per hour. An integrated metal.ID spectra (LIBS) library is available for metallic elements and several alloy materials.
SPE-i raman.ID +metal.ID enables you to determine chemical elements as well as chemical structure information using Raman Spectroscopy for particles at a rate of thousands per hour. For the first time two orthogonal spectroscopy technologies can identify unknown particle material. Thanks to the intuitive software control, you will be able to obtain statistically relevant information after a short introductory training period. Simply insert the sample, select the relevant particle size and shape, then allow the system to identify the exact chemical composition and elemental distribution at a throughput rate of 100 - 1000 particles per hour.
