On cruises with short transit times, perform, in port, as many of these the following as possible.:

Lab orientation/Introduction

...

• • Alkalinity/pH/chloride titrations
    • Alkalinity: Prepare 20 mM and 40 mM standards if necessary 
    • Chlorinity: Prepare 2 liters of dilution solution
  • Coulometer
    • HCl solution, KOH and AgNO3 solutions if needed
  • IC 
    • all solutions except for anion eluent, which should be made shortly before analysis
    • pourable calibration standards
  • ICP
    • 2% and 3% TM nitric acid solutions, also 10% if doing analyzing hard rock
    • internal standard(s)
    • primary in-house cocktail
    • pourable in-house and IAPSO calibration standards
  • SPEC
    • Ammonium
      • Ammonium standard and (dry ammonium chloride in oven overnight) + calibration standards
      • , alkaline solution
    • Phosphate 
      • Phosphate primary standard (dry monobasic potassium phosphate in oven overnight) + calibration standards
      • Sulfuric acid solution
      • Antimony potassium tartrate solution
