Before testing, samples must be cooled to 25O C (77O F) by collecting through a sample cooler for saf

If the sample remains cloudy after the first filtering, the sample should be refiltered through the same filter paper since the filter becomes more retentive on the second filtration

5、e112-ml1. Rinse and fill the plastic titration vial to the line (12-ml) with the cooled boiler water sample (Figure 1). 2. Pipette 2-ml of Barium Chloride 10% into the vial and swirl to mix (Figure 2). 3. Add 2 drops of Phenolphthalein Indicator and swirl. IF THE SAMPLE DOES NOT TURN PINK, the Hydra
6、te Alkalinity level is zero. Record zero on the Onboard Graphing Log and adjust dosage to increase hydrate alkalinity. IF THE SAMPLE TURNS PINK, counting the drops, add Sulfuric Acid N/10 until the sample is colorless (disregard the eventual reappearance of a pink color). Swirl the vial between drop

Record the result and adjust dosage as necessary.2TEST RESULTS DOSAGE ADJUSTMENT1. Fill the sample cup to the 25-ml mark with cooled boiler water s
8、ample (Figure 1 & 2). 2. Place the AMERZINE corrosion inhibitor ampoules tapered tip into one of the four depressions in the bottom of the sample cup. Snap the tip by squeezing the ampoule toward the side of the cup. The sample will fill the ampoule and begin to mix with the reagent (Figure 1 & 2).
9、3. Remove the AMERZINE corrosion inhibitor ampoule from the cup. Mix the contents of the ampoule by inverting it several times, allowing the bubble to travel from end to end each time (Figure 3). 4. Wipe all liquid from the exterior of the ampoule and WAIT EXACTLY 10 MINUTES for full color developme

Direct the comparator toward a source of bright white light while viewing from the bottom. Hold the comparator in a nearly horizontal position and rotate it until the color sta

If the sample turns pink, add Gallic Acid while stirring until the pink color disappears. This neutralizes the sample (Figure 2). 3. Place
15、the electrode into the sample and take care to ensure that the liquid level is above its upper steel band. Stir the electrode gently in the sample to create a homogenous sample (Figure 3). 4. Allow time for the reading to stabilize. Note the reading on the display. 5. Record the result and refer to
