Positive Material Identification (PMI) is a fast and non-destructive method for verifying the chemical composition of metals and alloys. Portable and cost-effective, PMI can be performed in one of our labs, or in the field.
Positive material identification is a cost-effective method for confirming general material types. While not as thorough as other chemical analysis methods, PMI is a great option for confirming the alloy or type of large batches of material, testing finished components, re-certifying materials, Scrap Material and evaluating materials that cannot be destroyed, or shipped to a lab.
All incoming raw material is cross checked in an independent laboratory for their chemical analysis to ascertain that the supplier has send us the right raw material. After confirmation of the same, the raw material is assigned a number and is taken on stock.
During inspection or dispatch on the behest of the customer we can also arrange for PMI (Positive material identification) tests for the manufactured finish goods. We provide 100% traceability on our products without any exception. At Roll-fast you can demand any document related to the manufacturing history of the product even after 10 years of supplies. We have them on record.
Roll-Fast also provides as a service to our customer positive material identification for all finished and raw materials which are us ed in our factory, we also provide for Chemical testing and chemical analysis for bolts and nuts in an independent laboratory. All our raw materials are pre checked as soon as we get the raw material from the mill before it is incorporated in our manufacturing system. These raw materials are further given a raw material number and the complete manufacturing process or travellers carry this r aw material number which is always mentioned on our job card.
PMI with portable XRF-analyzer
As part of our On-site Metallographic Analysis, Element offers on-site PMI with a portable XRF-analyzer for identification of medium and high alloyed metals, such as stainless steels, nickel alloys, and copper alloys.
Our on-site PMI analysis services provide you with a rapid response to your material sorting requirements when shipping materials or parts to a laboratory is too slow or not possible.
XRF (X-ray fluorescence) is a non-destructive analytical technique used to determine the elemental composition of materials. XRF analyzers determine the chemistry of a sample by measuring the fluorescent (or secondary) X-ray emitted from a sample when it is excited by a primary X-ray source. Each of the elements present in a sample produces a set of characteristic fluorescent X-rays (“a fingerprint”) that is unique for that specific element, which is why XRF spectroscopy is an excellent technology for qualitative and quantitative analysis of material composition.
