PLAZMARK Discoloration Example Due to Ozone Gas (1)
PLAZMARK atmospheric pressure type can also be used as a simple monitor for ozone generators!
We investigated the discoloration caused by ozone gas on PLAZMARK O2 cleaning cards No. 1 to 3, which react with various radical species, and long labels No. 41 and 42 for atmospheric pressure plasma. The O2 cleaning cards No. 1 to 3, designed to discolor when reacting with various radical species in vacuum plasma, also discolor when exposed to ozone gas, which is a type of reactive oxygen species, under normal temperature and pressure. When the three types of O2 cleaning cards were treated in a vacuum plasma device, the color difference was found to be No. 1 high sensitivity > No. 2 medium sensitivity > No. 3 low sensitivity; however, in response to ozone gas, the results showed No. 1 high sensitivity ≈ No. 2 medium sensitivity > No. 3 low sensitivity, indicating different responsiveness. [Discoloration Test with Ozone Gas (Partial)] ■ Ozone Generator: Ozone generator OW-5 manufactured by IHI Agritech Co., Ltd. ■ Ozone Monitor: EG-2001 manufactured by Ebara Jitsugyo Co., Ltd. ■ Color Difference Meter: FD-5 fluorescent spectrophotometer manufactured by Konica Minolta (Measurement light source M1, illumination system C light source, 2° viewing angle) *For more details, please refer to the related links or feel free to contact us.
