Service Overview 1. True Density (Gas Displacement Method) Sample Requirements: Powder: Ideally 10 mL of sample. Bulk Material: Dimensions must be smaller than 15 mm in diameter and 35 mm in height, with a minimum total volume of 6 mL. Definition:True density refers to the actual mass of a solid material per unit volume in…
Overview Ellipsometry is a non-destructive optical technique used to measure the thickness and optical properties (such as refractive index and extinction coefficient) of thin films. It works by analyzing the change in polarization of light reflected off a surface. Key features of ellipsometry: Applications: Commonly used in semiconductor, optics, and materials science to characterize films…
Service Overview Hardness is the ability of a material to resist indentation by a harder object. It can also be described as the resistance to localized deformation, especially plastic deformation, indentation, or scratching. Hardness is one of the essential properties of a material and is inherently related to other strength and plasticity indicators. Hardness values…
Overview The profilometer is primarily used to measure the thickness of thin-film materials, assessing their standard properties. It is widely applied in fields such as solar thin-film materials, semiconductor wafers, microelectronic devices, thin-film chemical coatings, and flat panel displays. The instrument plays a critical role in the development and research of new thin-film materials. As…
Introduction to Rotational Rheometer Measurement Systems (Rotors): Coaxial Cylinder System (CC): Typically used for low-viscosity liquids but suitable for a wide range of fluids from low-viscosity to viscoelastic materials (e.g., from water-like samples to semi-solid creams). Easy sample loading with volume markers in the measurement cup. The large external surface area of the cup enables…
