Reagent Blank Correction
: This method needs a reagent blank
correction. A single blank vial may be used more than once; the blank
vial is stable up to one day (room temperature). For most accurate
measurement, run a blank for each set of measurements and always use
the same lot of reagents for blank and samples.
•
Preheat the Hanna Reactor C 9800 to 150 °C (302°F). For correct
use of the reactor follow Reactor Instruction Manual.
Use of the optional HI 740217 safety shield is strongly recommended.
Do not use an oven or microwave because leaking samples can
generate a corrosive and possibly explosive atmosphere.
• Remove the cap from two Reagent Vials.
• Add exactly 5.0 mL of sample to one vial (sample vial), and 5.0
mL of deionized water to the other vial (blank vial), while keeping
the vials at a 45-degree angle.
• Add the content of one packet of Potassium Persulfate for Phosphorus
analysis to each vial. Replace the cap tightly and shake gently the
vials until all the powder is completely dissolved.
•
Insert the vials into the reactor and
heat them for 30 minutes at 150°C.
