Abstract
A method for control or calibration in a chemical analytical determination using a dry analysis element comprising at least one color-producing reagent and a porous layer, wherein the method comprises applying an aqueous dispersion onto the porous layer and measuring the optical density of the color produced, wherein the aqueous dispersion comprises a substance which is the same as or similar to an analyte to be determined and water-insoluble particles dispersed therein, wherein the particles are particles of a homopolymer, a copolymer, phthalates, trimellitates, phosphates, benzoates, amides, phenols, aliphatic esters, hydrocarbons, halogenated hydrocarbons, adipates, sebacates and natural polymers.

A method for control or calibration in a chemical analytical determination using a dry analysis element, said dry analysis element comprising at least one color-producing reagent and a porous layer, comprising the steps of:
- applying an aqueous dispersion onto the porous layer;
- and
- measuring optical density of the color produced,
- wherein the aqueous dispersion comprises a substance which is the same as or similar to an analyte to be determined and water-insoluble particles dispersed therein wherein said water-insoluble particles are solid particles or liquid particles, said solid particles being selected from the group consisting of homopolymers and copolymers and said liquid particles being selected from the group consisting of adipates, sebacates, phthalates, trimellitates, phosphates, benzoates, amides, phenols, aliphatic esters, hydrocarbons, halogenated hydrocarbons, and natural polymers.
