*WARNING: Reagents marked with a * are considered hazardous substances.
Material Safety Data Sheets (MSDS) are supplied for these reagents. For your
safety, read label and accompanying MSDS before using.
To order individual reagents or test kit components, use the specified code
number.
USE OF THE OCTET COM PARA TOR
The Octet Comparator contains eight permanent
color standards. A test sample is inserted into the
openings in the top of the comparator. The sample
can then be compared to four color standards at
once, and the value read off the comparator. For
optimum color comparison, the comparator should
be positioned between the operator and a light
source, so that the light enters through the special
light-diffusing screen in the back of the comparator.
Avoid viewing the comparator against direct
sunlight or an irregularly lighted background.
PRO CE DURE
A blank should be run on the test sample in the following manner:
Fill a test tube (0898) to the lower line (5 mL) with sample water. Add
5 drops of Aluminum Complexing Reagent (7868). Cap and mix.
Follow Steps 2 through 5 below. Subtract this blank reading from the
test results.
1. Fill a test tube (0898) to the lower line (5 mL) with sample water.
2. Use the 0.05 g spoon (0696) to add one measure of *Aluminum
Inhibitor Reagent (7865). Shake until powder dissolves.
3. Use a 1 mL pipet (0354) to add 2 mL of *Aluminum Buffer
Reagent (7866).
4. Use a second 1 mL pipet (0354) to add 1 mL of Aluminum
Indicator Reagent (7867). Cap and invert several times to mix.
Wait 5 minutes.
5. Insert test tube into Aluminum Comparator (7869). Match sample
color to a color standard. Subtract reading from blank. Record as
ppm aluminum.
NOTE: Color begins to fade after 15 minutes.
NOTE: If the color is darker than that of the 0.5 ppm standard,
the test should be repeated on a dilution of the original sample and
the test result multiplied by the dilution factor. For example, if 1
mL is diluted to 5 mL with distilled water, multiply the result by 5.
