In the test method, a first sample of the water is colorimetrically analyzed in a reaction chamber using a “molybdenum blue” test in which silica and phosphate in the sample are complexed with a first reagent. The phosphate complexes are then optically inactivated by a second reagent and the color of the silica complexes is intensified with a third reagent. From this, the silica content is calculated. A further sample is colorimetrically analyzed without using the second reagent, so that a combined silica and phosphate content of the further sample is obtained. A value of the silica content is subtracted from the value of the combined silica and phosphate content, resulting in a phosphate content for the sample. The silica content and the phosphate content of the sample are reportable."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Instrument for sequential analysis for silica and phosphate in aqueous solution","description":"A sample of water is tested for silica and phosphate content in a single apparatus.
