Glass Expansion从上世纪80年代就开始制造ICP发射分光仪和质谱仪的样品导入部件。 如今我们为16家制造商的设备提供支持，为50多个不同型号的ICP和ICP-MS设备提供样品导入系统。 许多主要ICP制造商将我们的产品作为标准提供。 我们的产品应用广泛，受到ICP行业公认分析师的欢迎， 被誉为“行业标准”产品。 对于不同样品导入部件之间的关系我们有着深刻的理解， 同时又有生产优质雾化器、雾化室、炬管和其他ICP部件的能力及专门技术，因此能够为你提供符合您ICP样品导入需要的全套解决方案。 下面就例举一些我们致力研究开发获得的成就：
Glass Expansion采用旋流式雾化室，对雾化室设计进行了彻底改革。 事实上，在Tracey旋流式雾化室出现前， Scott式雾化室是行业标准。 而我们的旋流式雾化室设计则能帮助您获得更高灵敏度，减少冲洗时间并降低基体效应，这是其他类型的雾化室无法做到的。
我们的可完全拆卸式炬管也名列行业第一，所有的部件都可拆卸和更换。这使得炬管的操作和使用更为有效，费用更低。 在高精度炬管的基础上，您可以任意更换三个独立导管其中之一，同时确保轴心准确对齐。 所有更换部件的制造均相当精密，更换导管后无需进行任何优化。 炬管导管的更换快捷简便，减少了停机时间并增加设备生产力。
我们制造的雾化器能够在ICP仪器制造商指定的气体压力和流量条件下以最佳状态运行。 我们生产的并不是只能在某一特定气体压力和流量范围内操作的雾化器，在追求质量方面我们精益求精。 我们按照您的ICP规格生产雾化器，因为我们了解这些规格的重要性。 同时我们也了解时间对您是何等重要，因此每次更换雾化器后您不必再费时重新校准仪器。
在ICP分析中，分析结果的再现性是极其重要的。 产品或变量的极小变化或不一致都可能导致分析结果的显著变化。在这样的环境中，设计质量和可靠性十分重要。 Glass Expansion已开发了独特的专有生产方式，能够生产高机械强度以及微米级尺寸精确度的部件，能满足所有最严格的分析规格。 我们产品因极佳的精度、成本效益以及结果再现性而在世界范围内获得认可。 再现性的优势如下：
短时间背景和 RSD 较低
长时间漂移较小
对于连续测试批号的Glass Expansion部件，测试的分析结果分散性较小。
本公司的设计和生产过程能确保产品性能的可靠性，有助于将可能影响分析的变量降至最低。 您的需要是我们产品设计品质、可靠性和创新的指南。 我们最近对顾客的需要进行了回应，由此开发出了简单实用的解决方案，例如用于雾化器的快速连接器件 EzyFit 和 EzyLok、用于炬管的 GazFit 接头，以及用于连接双层雾化室冷却液软管的 EzyLok。 我们以能满足顾客的需要而自豪。
Glass Expansion has been manufacturing sample introduction components for ICP emission and mass spectrometers since the early 1980s. Today we support instruments from 16 manufacturers, providing sample introduction systems for over 50 different ICP and ICP-MS models. Many major ICP manufacturers supply our products as standard. Our products are widely used and embraced by recognised analysts in the ICP industry, and are recognised as 'industry standard' products. Our intimate understanding of the relationship between the various sample introduction components, together with our ability and expertise in manufacturing high quality nebulizers, spray chambers, torches, and other ICP components, means that we can offer you a complete solution to your ICP sample introduction needs. Here are some examples of what our commitment to research has accomplished:
Glass Expansion revolutionized spray chamber design by introducing cyclonic spray chambers. That's right, before the 'Tracey' cyclonic spray chamber, Scott-style spray chambers were the norm. The design of our cyclonic spray chambers helps you achieve sensitivity gains, reduced washout times, and reduced matrix effects not possible with other types of spray chamber.
Our fully demountable torches, with all components being removable and replaceable, are also an industry first, enabling you to make operating and using torches more efficient and less expensive. With the high-precision ground torch base, you can replace any of the three individual tubes while maintaining accurate alignment and concentricity. All replacement components are so precisely manufactured that you don’t need any further optimization after you’ve replaced a tube. Changing torch tubes is so quick and easy, reducing down time and increasing instrument productivity.
We manufacture nebulizers to operate optimally at the gas pressures and flow specified by the ICP instrument manufacturers. Instead of manufacturing nebulizers which operate within a certain gas pressure and flow range, we go the extra distance in our drive for quality. We manufacture our nebulizers according to your ICP specifications because we understand how critical these specifications can be. We also understand that your time is important and that you shouldn't have to waste it on recalibrating your instrument each time you change your nebulizer.
Reproducibility of analytical results in ICP analyses is of paramount importance. In an environment where a small change or inconsistency in a product or variable can result in a dramatic change in analytical results, design quality and reliability is essential. Glass Expansion has developed unique and proprietary manufacturing methods, which enable the production of components with the high mechanical strength and micron-level dimensional accuracy to satisfy the narrowest of analytical specifications, each and every time. Our products are recognized world wide for their excellent precision, cost effectiveness and reproducibility of results. This reproducibility provides you with the following benefits:
Short-term background and RSD's are lower
Long-term drift is lower
Analytical result spread, measured for successive test batches of Glass Expansion components, is narrower
Our design and manufacturing processes ensure reliability in the performance of our products, which helps you minimize variables that can affect your analyses. Your needs are the crux of our product design quality, reliability, and innovation. Some of our recent responses to your needs have led to the development of user friendly solutions such as our quick connect EzyFit and EzyLok fittings for nebulizers, GazFit connectors for torches, and EzyLok fittings for jacketed spray chamber coolant hoses. We pride ourselves on being attentive to your needs.
