USE OF THE OCTET COM PARA TOR
L
Mott
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
1. Add 10 mL of Sulfur Dioxide Absorbing Solution (7804) to the impinging tube. Connect impinging apparatus to intake of air sampling pump. Make sure the long tube is immersed in the absorbing solution. Sample at 1.0 LPM for 30 minutes or until a measurable amount of Sulfur Dioxide is absorbed. Cover impinging apparatus with aluminum foil to protect from light.
2. At the end of the sampling time fill the small test tube (0230) to the line with the absorbing solution from the impinging tube. Use the 0.25 g spoon (0695) to add one level measure of *Sulfur Dioxide Reagent #1 (7693). Cap test tube and shake vigorouly to dissolve the powder.
3. Use a 1 mL pipet (0354) to add 1 mL *Sodium Hydroxide, 1.0N (4004PS) to the same small test tube (0230). Cap and invert several times to mix.
4. Use the other 1 mL pipet (0354) to add 2 mL (2 measures) of *Sulfur Dioxide Passive Bubbler Indicator (7805) to a large test tube (0204).
5. Pour the contents of the small test tube (0230) into the large test tube (0204) containing the indicator. Immediately cap tube and invert 6 times, holding cap firmly in place with index finger.
6. Wait 15 minutes. Place test tube into the Sulfur Dioxide Passive Bubbler Comparator (7746). Match sample color to a color standard. Record index number from comparator.
