点击翻译按钮获取中文摘要

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Instrument upgrades performed on the (1) Finnigan LCQ Classic, (2) two Finnigan LCQ DECA mass spectrometers, (3) LC Packings Ultimate and (4) the Pharmacia Smart HPLC Systems. Service in the mass spectrometers included maintenance of vacuum pumps, cleaning of the ion source, replacement of ion detectors, repair of electronics; the HPLC systems required maintenance of piston and syringe pumps and replacement of seals, check valves and tubing. Completed installation of a sample preparation robot (Probot). Optimized the procedure for direct sample deposition on a CD surface using the probot.
