Start on the GC.
2. The chromatogram should be similar to Figure 9.
3. The acceptance criteria are:
• Area counts for components labeled C14, C15, and C16 are all > 4,000.
• The area counts ratio calculated as C14/C16 is 1.00 ± 0.05.
• MDL (C16, pg/mL) = (436,000 × peak-to-peak noise)/(Area C16) ≤ 4.
4. If these criteria are not met, repeat the test. If after repeated testing the
criteria cannot be met, consult your service and user documentation for
additional information.
