The diagnostic tool comprises a permanganate-based colorimetric indicator formulation and a translucent assay container for containing the permanganate-based colorimetric indicator formulation. The diagnostic tool is characterized therein that the permanganate-based colorimetric indicator formulation is admixed with a product sample to be tested so that the admixed permanganate-based colorimetric indicator formulation undergoes a colorimetric reaction in the presence of organic residues in the product sample, the arrangement being such intensity of the colorimetric reaction displayed provides a semi-quantitative determination of a concentration of organic residue dissolved or suspended in the product sample."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Diagnostic tool for colorimetric detection of organic residues","description":"This invention relates to a semi-quantitative diagnostic tool and a method for using the same to verify the efficacy of cleaning-in-place procedures in eliminating carbohydrate-based, organic residues","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9797877","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
