• Turbidity Units of Measure
  Spectral absorption is expressed by Lambert-Beer's law and is based on compiled work by Pierre Bouguer and Johann Heinrich Lambert in the 1700's, as well as August Beer a century later. NTU FTU: Turbidity Units of Measure. English | Deutsch | Español. Home. About optek. Photometry. Products...
• MICRO: Optimizing polymers to increase pellicle lifetime and transmission for 157-nm lithography
  unpolarized light, improving results when dealing with thicker films by carefully treating nonidealities such as instrument bandwidth and sample nonuniformity. Purging the entire system with dry nitrogen gas can prevent the absorption of VUV light by ambient oxygen and water vapor. The instrument...

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...
• Cellulosics
  . Water absorption (which causes dimensional change) is also low, that of ethyl cellulose being lowest. The plasticizers in acetate are not as permanent as those in other plastics, however, and water absorption of this material is slightly higher. Butyrate and propionate are highly resistant to water...
• MICRO: Products
  size and count particles as small as 0.03 um. The product line monitors particle contamination in ultrapure water systems. Its large sample volume provides large amounts of statistical data (1.2 ml/min), and cosmic ray elimination has been added to the instrument for ultralow zero count, improving...
• Using VPD ICP-MS to monitor trace metals on unpatterned wafer surfaces
  techniques, such as atomic absorption spectrometry (VPD-AAS), total reflection x-ray fluorescence (VPD-TXRF), and inductively coupled plasma mass spectrometry (VPD-ICP-MS). Sample preparation has traditionally been performed manually; this article presents results obtained from a semiautomated sampling...

  Pressure-sensitive adhesives build stronger bonds. PSA tape from Avery Dennison Specialty Tape Div. bonds to a variety of surfaces and requires no heat, water, or solvent to activate. Electrical tape is a typical use of single-coated, self-wound PSA tape. Foam with PSA provides a tight wrap around...
