Moisture Content by Karl Fischer. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

Validating the specifications, value and safety of your raw materials, products and assets.

Moisture Content by Karl Fischer ASTM D

It can be more accurate than simple weight loss because e789 the weight loss method volatiles other than water can be lost which is translated into an artificially high water content. Standards can be obtained from appropriate standards authorities. Formally confirming that your products and services meet all trusted external and internal standards. Flow behavior is an indirect measure of product consistency and quality where materials must be consistent from batch to batch.

Moisture Content by Karl Fischer

Also, hygroscopic materials like nylon absorb moisture and knowledge of the water content can be important in understanding performance. If the temperature is too low or the retention time too short all of the water might not be driven off. Send us a request Need help or have a question? A temperature value too high can degrade the polymer and actually generate water in some cases. Enabling you to x789 and mitigate the intrinsic risk in your operations, supply chains and business processes.

Assurance Testing Inspection C789. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Send us a request Wilton UK: Need help or have a question? The time and temperature values are arrived at by testing a similar material and varying the temperature and bake time independently to determine optimal conditions for removal of all water in the sample.

Inspection Validating the specifications, value and safety astk your raw materials, products and assets. Karl Fischer is used to determine the water content of samples. The water in the sample is vaporized and carried by dry oxygen free nitrogen into a reaction vessel with methanol. A small weighed sample is placed into the Karl Fischer drying oven at a predetermined temperature for a predetermined period of time.

Formic acid is added to an eight ounce screw cap bottle filled with Also, molded parts can be compared to original resin to determine the extent of degradation from the molding process since degraded material would be lower in viscosity as a result of reduced molecular weight.

Standards can be obtained from appropriate standards authorities. Certification Formally confirming that your products and services meet all trusted external and internal standards.

The prepared solution is placed in the Brookfield Viscometer and a proper astmm is selected for the spindle according to the expected viscosity of the sample. Asttm of the moisture content can be important since some polymers degrade when molded wet resulting in reduced properties.
