完整LC-MS/MS解决方案用于环境和饮用水分析
赛默飞世尔科技推出完整LC-MS/MS解决方案用于环境和饮用水分析
2007年3月23日，圣何塞，加州，赛默飞世尔科技，服务科学的业界领袖，宣布推出一套完整的LC-MS/MS解决方案，在环境和饮用水分析中，可以显著减少分析时间和样本处理成本。EQuan 环境定量系统以赛默飞世尔科技的TSQ Quantum系列三重四极杆质谱作为主系统，用于分析杀虫剂、除草剂、杀菌剂和其它环境及饮用水样品中的药物。EQuan 特色的在线样品富集技术，可以显著减少分析时间从几天到几分钟，然而却保持了灵敏度和专属性。
通过EQuan，环境样品无需离线预浓缩处理，就可以直接注射进LC-MS/MS仪器分析，EQuan减少了样品制备过程，大大降低了样品处理的时间和成本。除此之外，在线的样品制备方法减少了人员操作的错误、以及样本的丢失。比仅使用三重四极杆质谱仪的传统LC-MS/MS，检测限高出了100倍，可以轻松获得10 ppt的检出限。
这项技术的基础是包含柱转换功能的在线提取方法。EQuan系统包括：一台TSQ Quantum™三重四极杆质谱仪，两个HPLC泵，分别带有一根预富集柱（Hypersil GOLD™ 12μm, 2.1х20mm），和一根分析柱（Hypersil GOLD, 3μmх50mm），一个 CTC 自动进样器，一个包含柱子和HPLC备件的EQuan组件包。EQuan可以使用TSQ Quantum™系列，包括TSQ Quantum Access™，TSQ Quantum Discovery MAX™或TSQ Quantum Ultra™。

Thermo Fisher Scientific Offers Complete LC-MS/MS Solution for Environmental and Drinking Water Analysis
SAN JOSE, CALIFORNIA (March 23, 2007) - Thermo Fisher Scientific Inc., the world leader in serving science, announces the release of an LC-MS/MS solution that significantly reduces the analysis time and cost of processing water samples in environmental and drinking water applications. The Thermo Scientific EQuan(TM) Environmental Quantitation System coupled with the Thermo Scientific TSQ Quantum(TM) triple quadrupole mass spectrometer is a turnkey system for the analysis of pesticides, herbicides, antimicrobials and other pharmaceuticals in environmental and drinking water samples. EQuan's unique on-line sample enrichment technique significantly reduces analysis time, from days to minutes, while maintaining sensitivity and specificity.
EQuan eliminates sample preparation by allowing samples to be directly injected and enriched followed by immediate LC-MS/MS analysis, thereby reducing both processing time and cost. In addition, the on-line sample preparation method reduces human error and consequent loss of sample. Limits of Detection (LODs) are considerably improved compared to conventional injection techniques (up to 100 times) with detection limits of 10ppt (parts per trillion) easily achieved.
Thermo Fisher Scientific offers a recorded webinar on the EQuan system's use for environmental and drinking water analysis. Presented by Jonathan Beck, Ph.D., this 25 minute webinar includes an explanation of the EQuan system, plus real-life data from EQuan customers, including the Laboratoire Department de L'eau in Toulouse, France. The webinar can be viewed at http://breeze.thermo.com/e94272249/event/registration.html?campaign-id=pr.
The EQuan solution consists of a TSQ Quantum series mass spectrometer, two HPLC pumps with a pre-concentration column, an analytical column, a CTC autosampler and an EQuan kit consisting of columns and HPLC accessories. EQuan can use any of the TSQ Quantum series instruments depending on the specific application, including the TSQ Quantum Access(TM), TSQ Quantum Discovery MAX(TM) or the TSQ Quantum Ultra(TM).
