关于处理si氧化锇的特别说明（参考文献5，附录A：2.5，“书籍”，电子显微镜程序）

“si氧化锇必须非常小心。晶体在40°C熔化，在水中溶解极慢。晶体和稀释的水溶液都能释放出si氧化锇的烟雾，即使在0°C时也是如此。低TLV（0.0002ppm）。因此，锇固定剂必须始终在通风橱（橱柜）中进行处理，因为它们的作用非常迅速，所以必须始终避免皮肤接触。

TLV =八小时平均阈值极限值，以毫克每立方米空气为单位。

形状和大小均一的纳米大小的金粒子是纳米技术（组装阵列），光散射（弹性-等离子共振；非弹性-拉曼效应）和单分子检测的无价工具。金纳米颗粒可以通过各种方法连接到蛋白质，链烷硫醇和DNA。银纳米颗粒正在发展与金纳米颗粒相似的功能特性。

Ted Pella，Inc.是为这些应用提供各种金纳米颗粒的。与我们的应用工程师联系，以了解新的开发/应用。我们一直在为新的纳米技术应用开发新的金胶体。

纳米金胶体的特征如下：

• 水中含有微量柠檬酸盐，单宁酸和碳酸钾的单分散金纳米颗粒
• 柠檬酸盐稳定并带有净负表面电荷（Langmuir 2005，21：9303-9307）
• 金胶体的pH值范围从5nm金的5以上到较大的粒子的9以下（pH随尺寸增加而增加）。
• 尺寸范围为5至250nm
• 粒子是拉曼或等离子共振光散射的宝贵工具（Analytical Chemistry 1999，71：4903-4908； Analytical BioChemistry 1998，262：137-156）

5nm至250nm尺寸的光散射程度不同，溶液颜色随粒径的增加而变化。 
 

已知这些产品在打开后至少可稳定一年。为避免打开后受到污染，宜在无尘室条件下操作产品，以免受到灰尘或其他空气传播污染物的污染。打开后，存储温度可从4-8°C（39-46°F（华氏度））到室温不等，具体取决于应用是诊断型还是研究型。胶体在沸腾时稳定，并通过冷冻破坏。当将产品存放在低于8°C（46°F）的温度下时，客户有责任确保其冰箱可以在上述范围内保持恒定的温度。

Mikrostik™胶粘剂

超薄粘性基底，透明，适用于其他粘合剂浸没的小颗粒。引用的应用包括有机粉末，花粉，种子-用于连接到SEM存根。可以用MEK稀释。快速干燥。非导电。

PELCO ^® Pro的氰基丙烯酸酯胶超

所述PELCO ^®临氰基丙烯酸酯基的瞬间或超级胶水是理想的修复，样品制备，组装和接合异种材料。透明，快速固化的氰基丙烯酸酯，无需混合或施加额外的热量。 
可提供带有5x2gr的小管套装，带分配器的20ml瓶或20gr分配器管。为了覆盖广泛的应用范围，提供了具有不同固化时间的不同粘度。 

氰基丙烯酸酯品牌交叉参考和技术数据

氰基丙烯酸酯胶（和环氧树脂）的货架期可以通过在较低的温度下保存来延长。-20℃。在较低的温度下，粘合剂变得非常粘，化学反应的速度实际上降低为零。它将使粘合剂稳定多年。使用前，将粘合剂融化并密封容器，以免凝结成粘合剂。 

PELCO ^®专业版C100氰基丙烯酸酯胶

PELCO ^®专业版C100 CA胶水有100CPS的粘度和4-10seconds的固化时间，明确的。用于将塑料，玻璃，陶瓷，橡胶粘合到表面中等光滑的金属上，不适用于多孔材料。通用型氰基丙烯酸酯胶。适用于许多应用。

PELCO ^® Pro的F5氰基丙烯酸酯胶-低气味/低白化（磨砂）

PELCO ^®临F5 CA胶是一个非常快的键合的氰基丙烯酸酯与5CPS的具有2-4秒，清晰的固化时间的粘度。适用于异种材料的高速粘合，具有光滑的表面和小的间隙（0.002英寸/ 50µm），具有优异的芯吸性能。不适合用于多孔材料。

PELCO ^® 高性能银浆

无机硅酸盐水溶液中的银薄片，专门配制的粘合剂，用于苛刻的粘合应用，如：

• 高温达927°C（1700°F）
• 超高真空 – 无碳氢化合物，无VOC
• 低温（适合性取决于匹配性能）

优异的导热性和导电性，加上不含碳氢化合物，使该产品成为FESEM，XPS，ESCA，SIMS，俄歇等应用中要求样品制备的理想选择。PELCO ^®高性能银浆提供具有20微米的银粒子尺寸兼具高导电和导热性。银含量> 60重量％。在室温下固化，但需要在93°C（200°F）下固化2小时，以达到高导电性和强键。在低温下使用本产品前必须*固化。易溶于水至260°C（500°F）。高于这个温度，它变得几乎不溶解。 
对于非导电的高温粘合剂，请尝试产品＃16026。

“Holey” (Perforated) Carbon Film

best general TEM astigmatism check

Thin films of carbon which have been treated to obtain a large number of small holes. Supported on a G400, 400 square mesh copper Gilder grid. Examination of the Fresnel fringe around the hole when the objective lens is slightly defocused enables astigmatism to be corrected. Observation of the fringe also gives an indication of TEM stability and available resolution. 

Carbon Conductive Tapes, Double Coated

These carbon tapes are conductive and may be used conveniently for scanning electron microscopy or EDS applications. 
This is the same material as the PELCO Tabs™, Carbon Conductive Tabs, but in tape form. The tape form allows for special application uses such as custom sizes, cut-outs and shapes. The purity of this tape is identical to the PELCO Tabs™; only very small impurities of Al and Si may be found. 

Both sides of the tape have a thick conductive adhesive (conductive inner film is 35µm and the adhesive is 45µm on each side for a total of 125µm [5 mils]) with a white liner. The double adhesive and conductive design permits quick mounting of samples without using liquid or colloidal adhesives. 
The tape is relatively solid and non-porous and does not absorb small samples. The variety of widths affords efficient application to various specimen mount surface sizes. Thickness is 0.16mm. Available in four widths. Can be used down to -20°C (-4°F) and temperature maximum is 60°C (140°F). Available in 8, 12, 20, 25, and 50mm W x 20m L (.31, .47, .79, .98, and 1.96″ x 21.8 yd). Core diameter is 76mm (3″). SEM mounts not included.
