美国科学系统公司SSI    
美国Scientific Systems, Inc.（SSI）是高效液相色谱仪的专业制造商,是实现HPLC系统真正商品化的首批厂家之一。美国Scientific Systems, Inc.自1967年成立以来一直致力于HPLC泵和其它部件的设计和生产，在这个方面具有世界最高水平的技术和生产设备，为目前世界四大制泵商一。1993年，SSI开始自行注册LabAlliance商标直接向市场供应高效液相色谱仪器，凭借其优质、价廉的特性，很快在欧美市场赢得美誉。1994年其液相色谱仪器进入中国市场，十年来拥有了大批用户。该仪器的操作在《中国药品检验标准操作规范》（2000版）有介绍。SSI高效液相色谱凭其过硬的质量，向客户做出免费保修三年的质量承诺。  
科学系统公司（SSI）1967年成立于宾西法尼亚州立学院（也就是宾尼法尼亚大学的前身）。从公司成立至今，SSI公司主要从事精密仪器的加工生产和高压流体技术方面的业务。虽然公司在州立学院只占地20000平方英尺，但是却给全球范围的用户提供着高质量的产品。

在20世纪60年代到70年代初，SSI公司生产高压阀（最高压力可达到100000PSI）和核工业用的其他组件产品。公司的这种生产能力在以后新的高效液相色谱即HPLC领域（在当时看来是新的领域）再次得到了认可。SSI公司与主要的厂商PE公司合作，在80年代初生产了10个系列的泵，以及其他一些液体流路产品。

从这个时期开始直到今天，SSI公司开发出了一系列的产品，其重点集中放在了成为主要HPLC行业供应商上。由于重点放在了高压活塞泵上，公司现在已经具有了电子方面的专业技术和仪器的设计以及配套的测试技术。公司的创新能力体现在泵柱塞杆的自动清洗设计和高压脉冲消除器的设计，另外，公司的其他核心产品的阀和其他流路产品也继续在生产供给。

SSI公司于1994年通过了ISO-9001的质量认证，直到今天一直在按照ISO－9001的要求进行生产。公司一直采样非常严格的质量控制系统。清洁、运转正常的设备和不断的改进创新始终贯穿于整个生产过程中。有了这些保障，SSI公司始终保持了产品的高质量，用户非常高的满意度，以及非常完善的售后服务。

1994年，SSI公司成立了一个分销公司LabAlliance，其主要是提供完整的HPLC系统，以及配件和软件。LabAlliance建立了可以提供检测器，自动进样器，馏份收集器和数据采集控制软件的网络。这些合作者允许LabAlliance公司通过全球的分销网络销售整个HPLC系统线的产品。LabAlliance的泵和检测器在中国有着很大的市场，其他第三世界国家对这种精确的化学分析仪器的需要也正在增长。

今天，SSI公司依然在给主要的OEM仪器生产商提供泵和其他组件，其中包括Waters公司，戴安公司，PE生命科学分析公司。超高压泵（18000psi）和组件产品也已经加入到公司的产品目录。公司的产品由于其非常好的稳定性，以及简单实用，性价比高，已经得到了广泛的认可。SSI公司的优势在于我们有能力为特殊的OEM企业定制生产产品，同时能保质保量的按时完成。

Scientific Systems, Inc. (SSI) was established in 1967 in State College, Pennsylvania, home of Penn State University. From the inception of the company through today, SSI has specialized in precision machining and high pressure fluid technology. The company maintains current operations in a 20,000 sq. ft. facility in State College, and maintains a worldwide customer base for its high technology products.
During the 1960s and early 70s, SSI produced ultra high pressure valves (up to 100,000 p.s.i.) and other components for the nuclear industry. This capability was later recognized by manufactures in the new field (at that time) of High Performance Liquid Chromatography, or HPLC. Working with a major supplier, Perkin-Elmer, SSI produced the Series-10 pump for this company through the early 80s, as well as other critical fluid path components.
From this time period through today, SSI has developed a wide portfolio of products, and has focused on becoming a premier supplier to the HPLC industry. With an emphasis on high pressure, positive displacement pumps, the company has a full engineering expertise in electrical and mechanical design as well as comprehensive machining, assembly and test operations. Innovative features like automatic piston wash and high pressure pulse dampeners have been developed and the core product line of valves and other fluid path components has also been maintained.
In 1994, SSI achieved ISO-9001 certification, and this recognition continues today. The company maintains a rigorous documentation control system, a clean, well maintained facility and pursues continuous improvement throughout all operations. Through these disciplines, SSI maintains the highest levels of product quality and customer satisfaction, along with full service capability.
Also in 1994, SSI launched a distribution division called LabAlliance, dedicated to providing a complete line of HPLC systems, accessories and software. LabAlliance established a comprehensive supply chain with manufacturers of Detectors, Autosamplers, Fraction Collectors and Data Acquisition & Control Software. These partnerships allow LabAlliance to supply a full line of HPLC systems through a worldwide network of distributors. LabAlliance pumps and detectors have found a major market niche in China and other third world countries where the need for accurate chemical analysis continues to grow.
Today, SSI continues to provide pumps and components to major OEM instrument manufacturers, including Waters Corporation, Dionex Corporation and PerkinElemer Life & Analytical Sciences. Ultra High Pressure Pumps and Components (up to 18,000 p.s.i.) have also been added to the product line. The company’s products are highly regarded for their reliability, ease of use and value. SSI’s strength is in our ability to customize products for specific OEM applications and then provide those products on time with the highest Quality.
