Huguenot Labs Inductively Coupled Plasma Mass Spectrometry ICP-MS deposit analysis testing is used to determine the elemental components of a deposit. This ICP-MS test is a very powerful tool for trace Part’s Per Billion- Parts Per Million (ppb-ppm) and ultra-trace (ppm-ppb) elemental analysis. The Pipe analysis and ICP-MS test does not determine if the pipe was manufactured to ASTM requirements. It does however give you a detailed breakdown of the material being removed from the walls of the pipe due to corrosion and/or MIC. Included in this test is “Stereomicroscopic” photos giving a visual view of the deposit analysis.
