MET-Biodiesel

  • Application: This rugged metal column was designed specifically for the determination of free and total glycerin in B100 biodiesel samples. A guard is integrated, thereby providing protection with a leak-free connection (the guard and analytical column are one continuous piece of tubing; there is no union between the guard and analytical column).
  • USP Code: None
  • Phase: Bonded; proprietary
  • Temp. Limits: -60 °C to 380 °C (isothermal) or 430 °C (programmed)

The rugged metal MET-Biodiesel column requires different care and use than fused silica columns.
  • Identifying the integrated guard: An aluminum tab is bent over a section of the integrated guard. Tailing peaks may indicate the column is installed backward.
  • Cutting a metal column: Score hard/saw with a ceramic wafer, grab the end to be discarded with needle-nose pliers, and then snap off.
  • Injector inserts: For Agilent 5890/6850/6890/7890 systems with a cool-on-column injector, an insert for 0.53 mm I.D. metal columns is recommended instead of an insert for 0.53 mm I.D. fused silica columns. This will help prevent damage to autosampler syringe needles. The insert for 0.53 mm I.D. metal columns has 4 lines on it (Agilent P/N 19245-20780). The insert for 0.53 mm I.D. fused silica columns has no lines on it (Agilent P/N 19245-20580).
  • Conditioning: Install, establish flows, wait 15 minutes, confirm flows, and then run through the oven temperature program three times. Hold at the upper temperature 30 minutes at the end of each cycle.
