概要	A new type of flow injection analysis (FIA) combined with a high-temperature reactor maintained at 100–400 C, namely hydrothermal flow injection analysis (HT-FIA), has been successfully applied to high throughput determination of Ru(III) on the basis of a conventional chromogenic reaction with 1,10-phenothroline (phen). Although this classical chromogenic reaction using phen is sensitive and selective for Ru(III), the complex formation of Ru(phen)3 requires 2 h. The acceleration using HT-FIA is extraordinary high so that the determination reaction of Ru(III) was successfully shortened to 5 s at 150 C, where the analytical procedure was accelerated more than 1000-fold. This enabled a high-throughput analysis of Ru(III) with 100 mL sample, of which at least 10 samples can be analyzed within 10 min. The detection limit of Ru(III) determined on the basis of 3 times of standard deviation was 53 pmol or 5.4 ng Ru in 100 mL sample.
