GB/T 6682 Specification and Test Methods for Water Used in Analytical Cleanrooms (GB/T 6682-2008, so 36961997, MOD) Summary of 3 methods: Fill a measuring cylinder with 4 oil samples and 40 mL of Yande water, and stir for 5 minutes at 54 ℃± 1 ℃ to form or emulsion, Measure the time required for emulsion separation (i.e., when the volume of the emulsion layer is not greater than 3 mL). After 30 minutes of rest, if the dye whip is not completely separated from the gold, or if the emulsion layer is not reduced by 3 L or less, record the volume of the oil layer, water layer, and emulsion layer at this time. 4 Reagents and materials 4.1 Petroleum ether: partition, 6o c-9o c.?
