美国Chemplex Industries有限公司专业从事样品前处理设备、耗材研发和生产的公司，是X射线光谱仪（XRF）配件耗材领域的全球知名厂商。Chemplex XRF样品杯和样品膜用于RoHS、WEEE专业测试仪器盛放小颗粒固体，粉末，液体，适用于各种品牌的X射线荧光光谱仪。Chemplex样品膜薄膜张力特性极*佳，与样品杯组合使用，适合盛放各类金属重物、液体或粉末。Chemplex的许多XRF样品杯、样品薄膜被列为新颖独特的设计和应用，并被美国专利商标局授予知识产权地位.磨损微粒化添加剂 ● 改善分状制备品 ● 减少颗粒尺寸与分布均匀● 促进样品均匀性● 将粉末转化成“增塑”球团● 解决试样球团崩落或剥落问题 Chemplex® 添加剂的配方与适当的平衡磨料和润滑成分，以促进磨削和造粒过程。当使用Chemplex添加剂，所得到的样品颗粒具有无瑕疵光滑表面的特征，表现为“增塑”。Chemplex添加剂有多种形式，使得它们使用起来非常简单：散装粉末、预加重和_克片剂。Chemplex添加剂也用作稀释剂，但是使用最少量的添加剂可以最小化稀释的影响。更多信息咨询美同达磨损微粒化添加剂规格: 添加剂 化学成分X-Ray Mix® C: 48.7% O: 42.6% H: 8.1% B: 0.6% SpectroBlend® C: 81.0% O: 2.9% H: 13.5% N: 2.6% Boric Acid O: 77.6% H: 4.9% B: 17.5% 注意:些添加剂可能含有可能干扰给定分析的微量元素。建议在进行分析调查之前，运行一个“空白”来评估存在和干扰水平。® X-Ray Mix, SpectroBlend and Chemplex are registered trademarks of Chemplex Industries, Inc.Generally, samples deficient in hard abrasive particles evade the effects of grinding and generally tend to agglomerate. The underlying sample particles protected by the outer layers of a sample elude comminution resulting in an increase in heterogeneity. Many other types of samples are comprised of very hard particles, deficient in cohesiveness that tends to resist pelletizing and exhibit fissure development, chipping or flaking apart during handling or analysis. The lubricious constituents of Chemplex® additives impart binding to the sample and conduciveness to briquette formation. The resultant sample pellets are characterized with unblemished smooth surfaces appearing “plasticized.” Frequently, the metallic grinding media is influential to the comminution process. The frictional heat generated by the grinding media tends to soften the sample creating a “caking” effect shielding the underlying mass from further comminution. The recommended starting point is to evaluate a 1 to 2-1/2 wt.% additive-to-sample weight (e.g. 0.1 to 0.25gm additive to 10gm sample). Adjust the additive-to-sample weight ratio until the optimum grinding and briquetting combination is achieved. Reference materials should similarly be prepared for matrix compatibility.典型应用领域：水泥■ 生搅拌 ■ 熔渣■ 炉渣■ 催化剂■ 矿石■ 耐火材料■ 肥料■ 土壤■ 磷矿石 ■ 氧化物■ 氧化铝 ■ 铝土矿■ 碳酸盐岩■ 硅酸盐■ 有机物■ 无机物■ 以及许多其他类型的样品物质，在粒度减少、分布和压块方面表现出困难Additive Prominent Characteristics X-Ray Mix® General purpose grinding agent. Balanced for abrasiveness and lubricity to aid in grinding dissimilar particles of moderate hardness for relatively short times. Highly “plasticizes” and firmly bonds samples together under briquetting pressure. Available in pre-weighed ? and ? gm tablets for ease of dispensing.SpectroBlend® A 44μm powder well suited for blending and as a diluent for high concentrations. Well balanced with abrasive and lubricious constituents for grinding most sample materials emphasizing difficult-to-process samples requiring long grinding cycles in metallic comminution vials or dishes. Resistant to degradation by thermal and irradiation exposure. Samples have “plasticized” surfaces. Available in bulk powder and ? gm pre-weighed tablets for ease of dispensing.Boric Acid Abrasive substance for processing samples with strong re-welding tendencies. Sample pelletsfairly to moderately bond together. Frequently used in conjunction with other additives to impart increased abrasiveness to the grinding process.订货信息： Cat.No.Description 600X-Ray Mix® , Powder 1lb per bottle625X-Ray Mix® , 1/4gm Tablets 500 tablets per bottle650X-Ray Mix® , 1/2gm Tablets 500 tablets per bottle660SpectroBlend® , 44μm Powder 1lb per bottle690SpectroBlend® , 1/2gm Tablets 500 tablets per bottle750Boric Acid,1/2gm Tablets 1000 tablets per bottle
