Mass Spectrometer Data System Upgrade

9317691威尔金斯这项提案要求提供支助，以允许更换控制南加州区域质谱学设施内两台质谱仪的过时的pdp-11计算机系统。这台计算机控制着一台VG-7070和一台VG-ZAB质谱仪，这两台质谱仪为主要在生物、生物化学和化学领域进行研究的南加州学术科学家提供服务。它的目的是用两个现代化的独立系统以及必要的接口硬件和软件来取代目前速度较慢的单台计算机。这次计算机升级将大大减少质谱仪样品的周转时间，并消除两台质谱仪因一台计算机故障而无法操作的可能性。如“项目说明”部分所述，质谱分析是任何涉及制备和表征具有生物功能的化学品的合成研究的重要组成部分。因此，拟议的设备升级预计将对所有设施用户的研究进度产生重大影响。

9317691 Wilkins This proposal requests support to permit replacement of an obsolete PDP-11 computer system controlling two mass spectrometers located in the Southern California Regional Mass Spectrometry Facility. That computer controls both a VG-7070 and a VG-ZAB mass spectrometer which provide services to Southern California academic scientists doing research primarily in the fields of biology, biochemistry, and chemistry. It is intended to replace the current slow single computer with two modern independent stand-alone systems, along with the requisite interface hardware and software. This computer upgrade will substantially reduce mass spectral sample turn-around times and eliminate the possibility that both mass spectrometers become inoperable as a result of a single computer malfunction. As described in the "project description section" mass spectrometric analysis is a vital part of any synthetic research involving preparation and characterization of chemicals with biological functions. Thus, the proposed equipment upgrade is expected to have a major impact upon the rate of research progress for all facility users.
