Polymer GPC was performed on two 300 x 7.5 mm Polymer Laboratories PLGel 5. µM mixed-C columns with Waters Associates liquid chromatography 2996 photodiode. array absorption. Polymer...
• Rapid parts for the long haul
  as a plasticizer that reduces the interactions of polymer chains and allows for greater extension. WATER ABSORPTION. Researchers watched how the various postcured samples absorbed water at room temperature for up to one year. The water uptake of the ProtoTherm 12120 material was extremely low. The UV...
• Using VPD ICP-MS to monitor trace metals on unpatterned wafer surfaces
  were made of high-purity Teflon and were precleaned. Instrumental analysis was performed using the Elan 6000 ICP-MS (Perkin-Elmer SCIEX Instruments, Concord, ON, Canada), with the MCN-6000 microconcentric nebulizer (Cetac Technologies, Omaha, NE) as the sample introduction system. A small amount...
