A chemical test kit and method for detecting the presence of impurities in an oil sample is provided. The test kit is comprised of two flexible translucent or transparent containers, each with at least one breakable capsule mounted within it. One of the flexible containers has a means for separating an aqueous layer from an oil layer. The capsules contain reagents capable of extracting the impurity to be detected from the oil into an aqueous layer and indicating the presence of a threshold concentration of the impurity. The method involves the steps of introducing an oil sample into a first flexible container, breaking the capsule within it by squeezing the flexible container in the vicinity of the capsule, transferring the aqueous layer to the second container, and breaking the capsule within the second container in the same manner. A chemical reaction occurs in the second container indicating whether the impurity is present at a given threshold concentration. |
