Acquisition of a Liquid Chromatography Mass Spectrometer for Mentored-Student Research in the Chemistry of Environmental Steroids and of Self-Assembled Monolayer Films

该合同将支持采购具有电喷雾（ESI）和大气压化学电离（APCI）探针和同步光电二极管阵列LC检测的液相色谱串联质谱计（LC- ms）。该仪器将用于环境生物学、生物化学和物理化学之间的合作研究，用于植物甾醇、雄激素甾醇和烷烃硫醇项目。质谱仪将使本科生受益于指导的研究项目，他们将为研究生课程和研究事业做好更好的准备。研究环境、动物和植物样品成分的学生将看到LC-MS在快速鉴定和定量方面的力量。这所大学理科专业的学生中有60%是女性。在过去的三年里，三分之二的理科毕业生是攻读生物和化学研究生课程的女性。

This award will support the acquisition of a liquid chromatograph tandem mass spectrometer (LC-MS) with electrospray (ESI) and atmospheric pressure chemical ionization (APCI) probes and simultaneous photodiode array LC detection. The instrument will be used in collaborative research between environmental biology, biochemistry and physical chemistry for projects on plant sterols, androgenic sterols, and alkane thiols.The mass spectrometer will benefit undergraduate students in mentored research projects, who will become better prepared for graduate programs and careers in research. Students studying the components of environmental, animal and plant samples will see the power of LC-MS in quick identification and quantification. The science majors at the university are sixty percent women. For the last three years, two-thirds of the graduating science majors have been women who have pursued graduate programs in biology and chemistry.
