品类先锋用户心得：珀金埃尔默8000型ICP测试陶土中钾钠元素实例

Core Viewpoint - The article emphasizes the importance of user feedback in evaluating the quality of scientific instruments, specifically highlighting the experiences shared by users of PerkinElmer's ICP-OES [1][4]. Summary by Sections Instrument Selection and User Experience - The article discusses the challenges faced by procurement users in selecting reliable and durable instruments from a vast array of brands in the market. It introduces "Category Pioneer," which aims to recommend trustworthy brands and instruments to enhance user selection efficiency [2][17]. - The initiative focuses on identifying top brands in specific subcategories that have proven their reliability through extensive user experience, thereby achieving significant market share both nationally and globally [2][17]. User Insights on PerkinElmer ICP-OES - The article shares user experiences regarding the PerkinElmer ICP-OES, specifically the Optima 8000 model, detailing its application in analyzing potassium (K) and sodium (Na) content in ceramic materials [5][7]. - A user conducted a quantitative analysis of K and Na in a batch of clay samples, providing data to support the optimization of ceramic production processes [7]. Experimental Methodology - The user describes the sample preparation process, which involves weighing 0.5000g of clay, adding specific reagents, and using a microwave digestion system to prepare the samples for analysis [8]. - The testing parameters include a radio frequency power of 1300W, an aerosol flow rate of 0.8L/min, and an auxiliary gas flow rate of 0.2L/min, with specific wavelengths for K and Na detection [10]. Results and Conclusions - The results indicate that the method used for testing K and Na content is precise, with a correlation coefficient (R²) greater than 0.999, and relative standard deviations (RSD) below 2%, confirming the method's reliability [11][12]. - The K content in the clay sample was found to be 2.87%, and the Na content was 1.53%, which meets the application standards for low-sodium clay [12].
