The patent, entitled "Skin Permeation
Device for Analyte Sensing or Transdermal Drug Delivery" issued to Echo Therapeutics in China, includes claims that encompass the skin preparation device, which prepares the skin in a controlled, dermabrasive manner to permit either drug delivery or analyte extraction.
For the packaging industry, Systech's oxygen permeation
and water vapour permeation
analyzers offer testing of all packaging film, finished package and PET bottles.
When the vulcanization temperature was 90[degrees]C, the permeation
flux reached a maximum while the separation factor achieved a minimum.
The intent of this study is to test the effects of FMP on fuel permeation
, to determine whether the material has any negative effects, and also, to test the effects of FMP on permeation
using ethanol-containing fuels.
Rhodia Engineering Plastics says the PA materials, part of the Technyl product line, control emissions to below emerging EPA and CARB permeation
Systech Illinois' leading oxygen permeation
analysers are capable of testing the oxygen barrier properties of packages with a detection threshold of 4E-05 cm[sup.
Subsequent to our earlier communications, in connection with the solvent transport characteristics of NR/EVA blends [11, 12] systems, the present examination aims at the solvent vapor permeation
properties of NR/EVA blend membranes using different organic solvents and their mixtures as penetrants.
3), and its effect on permeation
was documented in both a 1992 SAE paper (ref.
However, with Ixef low permeation
plastic, even the most stringent PZEV regulatory requirements may be reached with a minimum quantity of layers.
27mm thick, the Model 8001 can measure oxygen permeation
of plastic bottles, cans, containers and so on over a very wide measurement range of 0.
We're currently getting four to five times reduction in the permeation
rate of oxygen versus straight nylon 6 material," said Dahman.
com)-- Systech Illinois are global suppliers of permeation
analysers for the packaging industry.
