Chemistry (12) Gas chromatography-mass spectrometry (GC-MS) is becoming the definitive tool in the research and commercial analytical laboratory. To better prepare its students for graduate school and professional employment, St. Ambrose University is incorporating the use of GC-MS throughout the chemistry curriculum.Intellectual MeritThe project is adapting experiments from the educational literature, primarily from the Journal of Chemical Education, and is integrating those experiments into general chemistry and organic chemistry, and into advanced courses such as instrumental analysis and biochemistry. Through the use of GC-MS, students are learning to separate complex mixtures and identify their components. They are learning sampling techniques, use of external/internal standards, and single ion monitoring for rapid and reliable analysis. They are challenged to apply GC-MS to solve a variety of chemical problems, some investigating and reinforcing basic chemical principles, and others that provide very practical applications. This project also offers opportunity for the chemistry faculty to adapt experiments from the research literature in order to develop new GC-MS experiments in areas such as forensics, organic chemistry and physical chemistry. Results of these activities will be disseminated widely. Broader ImpactThis project impacts underrepresented groups since the majority of our students are women, and we rank in the upper quarter among Iowa four-year colleges and universities in our percentage of minority students. GC-MS experience is especially enhancing the training of majors in environmental science and in criminalistics who will assume positions as laboratory chemists after graduation. The work of such chemists is often of critical importance to society, and it is essential that their conclusions be accurate. Careful training early in students' professional education with instrumentation they will routinely use is essential to assuring their competency.

化学（12）气相色谱-质谱（GC-MS）正成为研究和商业分析实验室的决定性工具。 为了更好地为学生进入研究生院和专业就业做好准备，圣安布罗斯大学正在将GC-MS的使用纳入整个化学课程。智力优势该项目正在改编来自教育文献的实验，主要来自化学教育杂志，并将这些实验整合到普通化学和有机化学中，并整合到仪器分析和生物化学等高级课程中。 通过使用GC-MS，学生们正在学习分离复杂的混合物，并确定其成分。 他们正在学习采样技术，使用外部/内部标准，以及快速可靠分析的单离子监测。 他们面临的挑战是应用GC-MS来解决各种化学问题，一些研究和加强基本的化学原理，以及其他提供非常实际的应用。 该项目还为化学系提供了从研究文献中调整实验的机会，以便在法医学，有机化学和物理化学等领域开发新的GC-MS实验。 这些活动的结果将广为传播。更广泛的影响这个项目影响了代表性不足的群体，因为我们的大多数学生是女性，我们在爱荷华州四年制学院和大学中的少数民族学生比例排名靠前。 GC-MS的经验尤其加强了对环境科学和犯罪学专业学生的培训，他们将在毕业后担任实验室化学家。 这些化学家的工作对社会往往至关重要，他们的结论必须准确。 在学生的专业教育早期，他们将经常使用的仪器进行仔细的培训，这对确保他们的能力至关重要。
