What a routine PMI demonstration at a process plant revealed about replacement parts, documents, and the limits of visual inspection The components on the table During a recent Positive Material Identification demonstration at a process manufacturing facility, the maintenance and engineering team brought a set of components into the meeting room: a pipe elbow, a tee, a bolt, and a small instrument valve assembly still attached to its manifold. The situation behind the demonst

Which components warrant verification, at which points in the maintenance workflow, and how to turn testing into a documented programme The usual answer to “where should we be doing PMI?” is anywhere the material grade is part of the safety or corrosion case. True, and useless. A maintenance manager needs to know which items in a storeroom and which points in a workflow actually justify the time. Handheld XRF is a portable XRF instrument that requires minimal sample preparati

A requirements-first approach to instrument selection for PMI (Positive Material Identification), and how the ProSpector range from ELVATECH maps onto it. Elvatech is an established manufacturer of X-ray fluorescence (XRF) analysers, known for its ProSpector range of handheld instruments. The line is built to cover a broad span of material analysis — from dedicated heavy-element analysers suited to stainless, nickel and low-alloy steels, through to full light-and-heavy-elemen

The chromophores that give a gem its colour, the chemistry behind its value, and how to get a result you can trust !! Somewhere in Bangkok, a rough reddish-purple tourmaline was placed in front of an X-ray fluorescence analyzer. In sixty seconds it returned a set of numbers. Whether those numbers meant anything depended entirely on one thing most people never think about: how the instrument had been told to interpret what it saw. That single idea — that an XRF number is only

Why your handheld XRF shows “grade not identified” on coated parts — how to read Zn-Ni plating over steel correctly for PMI and material verification, and which ProSpector model fits the job.

How portable XRF lets gold and platinum mines grade ore on the spot, lift recovery 3–8%, and stop relying on week-old lab results.
