MEASUREMENT PROCEDURE

• Add the content of one packet of HI 93717B-P Amino

Acid powder to HI 93717B Amino Acid bottle when
you use it for the first time only. After you have
added the powder, replace the cap of the bottle and swirl it
gently for 2 minutes to dissolve the powder. Leave the bottle
undisturbed for about 5 minutes, then the reagent is ready.
Note: after adding the Amino Acid powder, the HI 93717B
reagent will last for about one month.

• Select the program number corresponding to Phosphate HR on

the secondary LCD by pressing PROGRAM W and V.

• Fill the cuvet with 10 mL of

unreacted sample (up to the
mark) and replace the cap.

• Place the cuvet into the holder and

ensure that the notch on the cap is
positioned securely into the groove.
