The Arc-Met 8000 is an excellent mobile OES spectrometer that delivers analysis results in the field or the shop floor. The Arc-Met was such an effective metal analyzer that Oxford engineers used it as the building block the PMI-MASTER Smart. The PMI-MASTER Smart used the best features of Arc-Met 8000 and incorporated new technology for better results and a lighter instrument.

What did the PMI-Master Smart use similarly to the ARC-Met 8000, and how does the PMI-Master go above and beyond?

Both instruments are purpose-built for accurate mobile analysis, but the Smart is a true road warrior. The PMI-MASTER Smart also can analyze all of the elements required by API 5L, product analysis reports, and store/compute CE calculations.



In sections 6.1.1 and 6.1.2 of API 5 L guidelines, it specifies that purchasers and buyers must know the chemical composition of OCTG for welding. At a minimum the operator must know the following elements:

  • Carbon
  • Manganese
  • Phosphorus
  • Sulfur
  • Chromium
  • Columbium (Niobium)
  • Copper
  • Molybdenum
  • Nickel
  • Silicon
  • Titanium
  • Vanadium

a. Boron. (But if the heat analysis indicates a boron content less than 0.00 I %, then no boron determination is required for the product analysis.)

b. Any other alloying element added during steelmaking for a purpose other than deoxidation. Calculation of Carbon Equivalent

For PSL 2 pipe, carbon equivalent (CE) calculations shall be based on the product analyses and shall be calculated as follows. All carbon equivalent results shall be reported:

a. When the carbon content is less than or equal to 0.12%, the carbon equivalent shall be calculated using the following formula for CE(Pcm) [see Note I]:

CE(Pcm) = C+ Si/30 + Mn/20 + Cu/20 + Ni/60 +Cr/20 + Mo/15 + V/10 + 5B

If the heat analysis indicates a boron content less than 0.00 I %, then the product analysis need not include boron, and the boron content can be considered as zero for the CE(Pcm) calculation.

b. When the carbon content is greater than 0.12%, the carbon equivalent shall be calculated using the following formula for CE(lIW) [see Note 2]:

CE(lIW) = C + Mn/6 + (Cr+Mo+V /5) + (Ni+Cu)15

If you travel between multiple locations or need a lightweight spectrometer for metal analysis, the PMI-MASTER Smart is a mobile spectrometer for you.


Periodic maintenance (PM) and calibration are essential tasks that you need to do on a regular basis to ensure that your equipment continues to function as intended.
