Ensure you prepare sufficient amounts of each solution, taking into account the volume required for priming
(~2mL per prime), calibration and sample analysis. It is recommended to prepare a total minimum volume of
20mL for each sample, and 250mL and 500mL of pre-mixed calibrant and blank, respectively.
4.4 Priming of Lines
Always prime both Port A and Port B lines 3 times before any analysis to ensure that both lines are filled with
liquid and there are no air bubbles present. This can be confirmed by visually checking all flow lines. For
automated system, 6 primes of Port A are required to accommodate the longer sampling line.
