Hach 16900 - Titrate the Sample

Figure 3 Install a titration cartridge
3.2 Titrate the sample
1. Prepare the sample as follows:
a. Add the applicable sample volume to a 125-mL or 250-mL Erlenmeyer
flask. Use the smallest possible size of graduated cylinder or pipet to
measure the sample volume.
Do the sample volume measurement and dilutions accurately. However,
the final total volume of titrated solution is not important.
b. Dilute the sample to the applicable total volume with deionized water, if
necessary.
c. Add the necessary reagents to the sample. Swirl to mix.
2. Titrate the sample as follows:
a. For fixed-position titration, attach the digital titrator to a laboratory stand
and use a magnetic stirrer. Refer to Figure 4.
b. Turn the counter reset knob to set the digital counter to zero.
c. Put the delivery tube tip in the solution and swirl the flask while titrating.
Turn the delivery knob to titrate.
