Karl Fischer

Moisture Content ASTM D 6869

Moisture Content by Karl Fischer ASTM D 6869

Scope: Karl Fischer is used to determine the water content of samples. It can be more accurate than simple weight loss because in the weight loss method volatiles other than water can be lost which is translated into artificially high water content. Knowledge of the moisture content can be important since polystyrene when molded wet resulting in reduced properties. Test Procedure: A small weighed sample is placed into the Karl Fischer drying oven at a predetermined temperature for a predetermined period of time. 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. If the temperature is too low or the retention time too short all of the water might not be driven off. A temperature value too high can degrade the polymer and actually generate water in some cases.  The water in the sample is vaporized and carried by dry oxygen free nitrogen into a reaction vessel with methanol. The methanol traps the water which is titrated to an end point with a Karl Fischer reagent to determine the amount present.  Specimen size: One to three grams. 

Multi elemental analyzer

Elemental Analysis


Elemental analysis, detection, identification and quantification testing. Elemental analysis and testing includes identification and quantification of elements, elemental compounds and molecular species. Sample types and matrices tested for trace elements include organic and non-organic, aqueous and non-aqueous materials. Elemental trace and ultra-trace analysis detection ranges from parts per million (ppm), to parts per billion (ppb) and parts per trillion (ppt) levels, using proven and up-to-date instruments and techniques.


Near Infrared Spectroscopy Analysis of Polymers and Plastics

Polymers and PlasticsNIR analysis capabilities and expertise.

NIR (Near Infrared Spectroscopy) is an effective analytical tool for screening and profiling polymer samples. NIR testing expertise provides valuable quantitative and qualitative analysis for polymer and plastic materials.

NIR identifies chemical bonds in a molecule by producing an infrared absorption spectrum in the range of near IR only which makes higher accuracy. The resulting spectra produces a profile of the sample, a distinctive molecular fingerprint that can be used to easily screen and scan samples for many different components. Polymer and Plastics NIR is an effective analytical instrument for detecting functional groups and characterizing covalent bonding information.NIR analytical testing and data interpretation for polymers are available globally.

NIR Polymer Analysis Solutions:

NIR is often used with other molecular spectroscopy techniques available at Estyrenics laboratories, including GC, UV/Vis spectroscopy. NIR combined with these techniques provides significant complementary data regarding a polymer molecule's molecular structure.
