Hygroscopicity of a material can be regarded as a physicochemical property that represents the ability of absorbing moisture from the surrounding environment. Recently, determination of the hygroscopicity is of great importance to select the most appropriate solid form of a drug substance for development. The pivotal effect of hygroscopicity evaluation in pharmaceutical development is mainly ascribed to the fact that the up-taken moisture may leads to significant adverse effects on the physical and chemical stability of the end products. For pharmaceutical development, the moisture sorption evaluation is always conducted during the early stages to optimize the formulation parameters, manufacturing process and establish a storage condition for the drug substances or end products.
Our Techniques for Hygroscopicity Testing
Such method is generally based on an analyzer of MCPC Moisture Computer and can be applied for a wide range moisture measurements such as major food products or the processing, some building materials, chemical compounds and bio/pharmaceutical products.
TA represents one of the most efficient, reliable and responsive methods for moisture determination. The primary principle of this methodology is to determine the weight loss of mass post heating the materials being tested at a certain temperature.
This method generally involves a more responsive radiator in heating and cooling requirement cycles than the infrared heaters, which results an accelerated responsiveness and saves the actual test cycle time. More importantly, when combining the thermogravimetric drying and halogen heating with highly accurate weighing technology, it can deliver a faster and more precise procedure for a wide array of moisture analysis.
We also provide clients with oven drying methods, which is commonly used for commercial purposes, such as substance vaporization, capacitance, Karl Fischer Titration, water activity, halogen and infrared drying methods, and the thermogravimetric method of infrared drying technique.
