Explanation: Alexander,
I tried 'intermediate solution' on Google and it seemed to work well.

Alexander,
It may still not be what you need, but I found the following: http://www.cybercolloids.net/library/jecfa/index.php?submit=...
Solutions:
Stock solution (1 mg/ml): Dilute an appropriate volume of certified reagent lead standard solution with distilled and deionized water (D/D water) to make one liter.
Intermediate solutions: (a) 100 µg/ml. Pipet 10 ml of the stock solution into a 100-ml volumetric flask and dilute to volume with D/D water. (b) 10 µg/ml. Pipet 10 ml of the 100 µg/ml solution into a 100-ml volumetric flask and dilute to volume with D/D water.
Working solutions: Assemble four 100-ml volumetric flasks and transfer to them (pipet), respectively, 1, 5, 10, and 20 ml of intermediate lead solution (b). Dilute to volume with D/D water to make solutions containing 0.1, 0.5, 1, and 2 µg Pb/ml.

Good to know that it helped. Enjoy the rest of the weekend.

Google links to "intermediate solution" are not decisive. These links all use use this possible translation it in the standard sense (i.e. a solution to a problem), not in the sense of "something dissolved in water or a fluid".
