Moisture content analysis for medical devices has never been easy. The resins are sophisticated and very expensive, the customers are demanding, and a minuscule cosmetic defect can mean the difference between thousands of dollars of saleable finished goods and scrap. When working with the complex, high-volatile-content materials that make up modern medical devices, every part per million counts, and every gram of resin counts. That’s why Computrac designed the Vapor Pro ...

Selerity SFC Custom Applications: Selerity SFC Custom Applications offer distinct advantages over gas chromatography (GC) and liquid chromatography (HPLC) when: Compounds are not volatile enough for GC without derivatization. Compounds do not have chromophores suitable for UV detection under HPLC conditions. Compounds are unstable at typical GC temperatures. Universal detectors such as the flame ionization detector (FID) are desired that are not available for ...
