نقد و بررسی تخصصی الکترود RDE دیسک حلقه چرخان مدل RRDE3-A شرکت ALS ژاپن
دستگاه الکترود دیسک حلقه چرخان RRDE -3A به منظور استفاده در الکتروشیمی مدولاسیون هیدروداینامیک و دیسک حلقه چرخان طراحی شده است. الکترود آن با قطر 7mm با شفت کوتاه از جنس استیل ضدزنگ به منظور ایجاد یک سیستم الکترودی حلقوی غلظتی کوچک که اندازه گیری بسیار دقیق از نوع مدولاسیون چرخشی و حتی قابلیت در سرعتهای مدولاسیون شعاعی و یا حتی نوع موجی را دارا میباشد.
RRDE-3A is electronically controlled by a proportional-integral closing loop circuit driving as an DC servo-motor. Electrodes are small and rapidly interchangeable. The unit also provides an adjustable valve system for inert gas purging inside the cell vial.
RRDE-3A is able to be operated as a stand-alone unit and directly controlled by CHI, BASi Electrochemical Analyzers or other instruments. When the analysis starts, a built-in gas control allows purging the sample. Besides, the access to glass cell is easy for rinsing, cleaning, and replacing the electrodes. It is easy to remove and replace the cell vial.
