Answer:Its nominal concentration is 0.1% water by mass, equivalent to approximately 1 mg H2O per gram of standard.
Answer:It is designed for coulometric Karl Fischer moisture analysis and instrument or method performance checks.
Answer:Ten glass ampoules are supplied, each containing 8 mL of certified water standard.
Aquastar Water Standard 0.1% is a certified reference material containing approximately 1 mg of water per gram of solution for verification of Karl Fischer water-content measurements. The low water concentration is especially suited to coulometric Karl Fischer titration, including control checks at the milligram water level. This package contains ten sealed 8 mL glass ampoules, allowing fresh reference portions for routine system performance checks. The standard is a moisture reference material rather than a Karl Fischer titrant or an unknown sample. Accurate results require careful ampoule opening, prompt handling, and calculation with the certified lot-specific water value and actual weighed mass of standard.
