  • 2
    mmol/l
  • Potassium:
  • 0.1
    mmol/l
  • Lithium:
  • 0.1
    mmol/l

    Linearity
  • Sodium:

    Reproducibility
    Based upon the measurement of 20 replicates over
    a 10 minute period, reproducibility
    will be better than:
  • Sodium:
  • (at 140 mmol/l level)
    1.5%    C.V.
  • Potassium:
  • (at 5.0 mmol/l level)
    1.5%    C.V.
  • Potassium:
  • (at 80 mmol/l level)
    1.5%    C.V.
  • Lithium:
  • (at 2.5 mmol/l level)
    2.5%    C.V.

  • Applications
    Flame photometry is well proven in clinical
    applications and is universally accepted as
    the reference method.
    The 405C will economically fulfill the
    requirements of:

  • Hospital Clinical Chemistry laboratories
  • Renal Dialysis laboratories
  • Independent Clinical Testing laboratories
  • Veterinary laboratories
  • Universities, Medical schools and
        technical colleges
