    The oral dissolving film is uniformly coated by a film applicator and then dried and formed.
    Oral dissolving films are prepared by a coating mechanism, where a liquid containing film-forming materials is uniformly applied onto a substrate, followed by drying to remove the solvent and form a solid film.
    Coulometric thickness gauge measures the sealing quality of anodic oxide films.
    This article introduces a method for assessing the sealing quality of anodic oxide films using a coulometric thickness tester. The sealing quality affects the corrosion resistance and wear resistance of the oxide film. Based on electrochemical principles, the coulometric thickness tester evaluates the sealing effectiveness by measuring the electric charge required to dissolve the oxide film, providing objective and repeatable results.
    Key operational points for determining the acid value of oils and fats using potentiometric titration.
    This article introduces the key operational points for determining the acid value of oils and fats using potentiometric titration. The method principle involves dissolving the oil or fat sample, titrating it with a standard alkaline solution, automatically determining the endpoint based on the potential jump, and then calculating the acid value using the formula.
    Usage of Paint Film Solvent Rub Tester in Rapid Detection of Curing Degree
    The paint film solvent resistance tester rapidly evaluates the degree of paint film curing by simulating solvent wiping. Its principle is that a fully cured paint film has a high cross-linking density, enabling it to resist solvent dissolution.
    Coulometric Method Coating Thickness Gauge for Non-Destructive Measurement of Precious Metal Coatings
    The coulometric coating thickness gauge measures the thickness by calculating the amount of electricity required to dissolve the precious metal coating through the principle of electrolytic dissolution. This method is non-destructive to the overall sample, only forming tiny electrolytic spots.
    Application of Electrolytic Thickness Tester in Quality Control of Precision Electroplating Layers
    The electrolytic thickness gauge measures coating thickness through the principle of electrochemical dissolution, calculating based on Faraday's law, offering high accuracy and independence from calibration.
    How does the instrument calculate total dissolved solids in water from conductivity?
    This article explains how TDS instruments estimate total dissolved solids by measuring the electrical conductivity of water. Since most dissolved solids exist in ionic form, which affects conductivity, there is a correlation between the two.
    Selection of Coating Thickness Measurement Methods: Coulometry vs. Dissolution in Electrolytic Thickness Gauges.
    This article compares two techniques in electrolytic thickness gauges: the coulometric method and the dissolution method. The coulometric method measures coating thickness through electrochemical dissolution, making it suitable for single-layer metal coatings with simple operation and high accuracy. The dissolution method, on the other hand, measures thickness via chemical dissolution, making it more appropriate for multilayer or complex coatings.
