refractive index

1. Food and beverage industry: Sugar content determination: used for quality control, maturity judgment, and adulteration detection of fruit juice, soft drinks, honey, jam, syrup, wine (potential alcohol content estimation), etc. Concentration measurement: measure the concentration of salt solutions, seasoning liquids, dairy products (such as whey concentration), edible oils, etc. Purity testing: Check whether fruit juice is mixed with water, honey is mixed with syrup, etc. 2. Chemical and petrochemical industries: concentration determination: measuring the concentration of acids, bases, solvents, antifreeze, cutting fluids, industrial cleaning agents, etc. Component analysis: assisting in determining the composition ratio of binary mixtures Purity identification: Quickly identify the purity of chemicals or solvents, as pure substances have a specific and constant refractive index. Petroleum products: measure the refractive index of lubricants, hydrocarbons, oils, etc. as an indicator of their composition and characteristics. 3. Pharmaceutical industry: drug concentration determination: measuring the concentration of drugs, injections, eye drops, syrups, etc. Identification of raw materials and auxiliary materials. Quality control: Ensure that the concentration of intermediates and final products meets process requirements. 4. Clinical and laboratory medicine: estimation of urine specific gravity (SG), determination of serum/plasma protein concentration, and detection of cerebrospinal fluid (CSF) protein. 5. Cosmetics and daily chemical industry: Product concentration and formula control. 6. Gemology and Jewelry Appraisal.
