  • Water Vapor Permeation Testing Of Ultra-Barriers: Limitations Of Current Methods And Advancements Resulting In Increased Sensitivity
    or altered In designing a more sensitive method the limitations of the current methods were first studied From there enhancements and modifications to the traditional comparative or concentration sensor produced an order of magnitude increase in sensitivity from 5x10 3 to 5x10 4 g m 2 day Permeation results illustrating the new system will be presented as the highlight of the paper Limitations found in the current methods alterations made to a traditional system and insight into future modifications that will increase the sensitivity even further will also be included A major hurdle for the introduction of flexible OLED s into the commercial market is the limited lifetime of the devices due primarily to the degradation in the presence of moisture and oxygen Permeation barriers are required to minimize the exposure of the devices to the moisture and oxygen in the atmosphere A water vapor transmission rate WVTR value of 1 x 10 6 g m2 day has become the unofficial standard for the OLED industry to achieve a device lifetime of 10 000 hours This value was originally estimated by calculating the amount of oxygen and water needed to degrade the reactive cathode Obviously an impediment is the development

  • Development And Testing Of A Rapid Protocol For Environmental Swabs Using An Oxygen-Depletion Technology
    plating on agar resulting in a high degree of manual labor and long periods of incubation up to 72 hours A new technology has been introduced that can reduce testing time and expense for very low bacterial loads on swabs hence highlighting areas of concern for QC staff and hygienists GreenLight is an assay that can relate oxygen depletion to microbial load In theory even the presence of one bacterium

  • Physical Testing Of Medical Packaging
    sterile from production to final use In its guidance the FDA lists four advantages of container and closure system integrity tests These include the ability to detect a breach prior to product contamination the ability to conserve samples that may be used for other stability tests the fact that they require less time than sterility test methods the fact that the potential for false positive results may be reduced But integrity testing offers other benefits as well Like traditional microbial challenge testing it can be used during package development for periodic checks on production or when critical events occur Unlike microbial challenge however integrity testing doesn t incur the delay required for culturing making it far more convenient and usable Nor does it require highly trained specialists or incur the same risk of operator error Ease of testing means packages can be tested more often over their anticipated lifecycle This can be critical for packaging that is shipped handled and otherwise challenged in ways that may affect its ability to keep contents sterile Package integrity testing using instrument methods can be more sensitive repeatable and reproducible and therefore more reliable Depending on package design a variety of package integrity testing

  • The Impact Of Permeation On Shelf Life And Packaging
    gauges wrong material choices etc allows the transmission of some compound s at a rate that causes product degradation faster than the desired shelf life Repercussions from under packaging can range from product complaints and returns all the way potentially to voided warranties law suits and legal action Over packaging probably will not result in legal action but can be a significant waste of money and material resources Often times a lack of product knowledge will lead a manufacturer to use the best package available within a given budget in order to prevent under packaging If the proper testing program had been implemented pre launch significant dollars could have been saved in wasted costly over packaging Furthermore once the product is a success it s often impossible to change anything connected with the package design for fear of losing market share At either end of the spectrum package design can have a potentially large impact on the environment As Figure 1b illustrates over packaging results in excessive material usage thus negatively impacting the environment Under packaging creates product returns resulting in increased waste again creating a negative impact on the environment BARRIER MATERIALS The knowledge and level of sophistication in the barrier plastic packaging business has skyrocketed as absolute barrier type packages such as cans and bottles has shifted to permeable packaging systems 1983 marked the introduction of a co extruded multi layer plastic ketchup bottle to the US supermarket shelves Since then companies have been working at a feverish pace on packaging strategy The competition is steep and product quality and package design could be the keys to market success Decision makers have an increasingly new variety of resins materials package configurations and technologies to evaluate Barrier levels of materials today range from ultra barriers used in the electronics
