To prepare the 1000 ppm standard
1. Place 3 mL of OIW Surfactant into the bottle marked 1000 ppm.
2. Pipette 100 µL of oil directly into the OIW Surfactant. Swirl the bottle until the oil is fully
dispersed in the OIW Surfactant.
NOTE: It may be necessary to heat viscous oils for accurate pipetting. A temperature of 120 °F
(49 °C) to 150 °F (66 °C) is usually sufcient. If you must heat the oil in order to pipette it, you should
also warm the OIW Surfactant in the 1000 ppm bottle before you add the oil. This will help the OIW
Surfactant fully disperse the oil.
3. Add distilled water to the 1000 ppm bottle until the liquid level reaches the 100 mL mark.
4. Cap the bottle and shake it vigorously for at least 15 seconds.
5. Place the bottle in the hot water bath and heat it until the contents are uniformly milky-white in
appearance.
6. Put on heat-resistant gloves suitable for handling glass bottles at boiling water temperature
(212 °F, 100 °C).
7. Remove the bottle from the hot water and, while the contents are still milky-white, shake the
bottle vigorously for at least 30 seconds.
8. Allow the 1000 ppm standard to cool to room temperature.
NOTE: You may accelerate cooling by placing the 1000 ppm standard in a refrigerator or a container
of cold water.
9. Fill a 3 mL syringe with the 100 ppm standard.
10. Attach an unused syringe lter to the end of the syringe.
11. Press the syringe plunger to lter the liquid into the 8 mm cuvette marked 1000 ppm. Continue
until the cuvette is ½ to ¾ full.

Settings screen.
