線上比色法分析水中二氧化矽 Online colorimetric analysis of Silica in water

Measurement Method: Colorimetric measurement at 630 nm using molybdate, conform with standard method ASTM 4500-SiO2-C 使用鉬酸鹽在630 nm處進行比色測量，符合標準方法ASTM 4500-SiO2-C

EZ1000 Silica Analyzers achieve excellent precision and accuracy. At the heart of the colorimeter there is a compact photometer assembly developed especially for the EZ Series. Consumption of reagents is reduced by low volume analysis, yet high sensitivity is assured by a long optical path length. The limit of detection is in the low µg/L range.
優異的精度和準確度。 專為 EZ 系列開發的精巧型光度計零組件。 低容量分析減少試劑消耗，而長光路長度達成高靈敏度。 檢測極限在低 µg/L 範圍內。

Precision micropumps dose all reagents. Sample lines and analysis vessel are cleaned with demineralized water to eliminate cross contamination between samples. Electronic and wet-chemical part of the analyzer are strictly separated. A transparent door allows for instant visual inspection of the wet part.
精密微型幫浦計量所有試劑。 樣品管線和分析容器用軟化水清洗，以消除樣品之間的交叉污染。 分析儀的電子部分和濕化學部分嚴格分開。 透明門設計方便操作人員即時目視查看潮濕部分。
