Improving Instruction for General Chemistry Students and Nonscience Majors Through the Use of Gas Chromatography

9451493 Brazdil毛细管气相色谱仪加强了理科专业和非理科专业提供的普通化学教学的基本化学原理。学生将使用常规化学家使用的仪器来更好地理解诸如定性鉴定、校准和定量、家用产品中化学物质的鉴定、亨利定律、物质的分配行为和勒夏特列原理等主题。此外，说明气相色谱法和纸层色谱法或薄层色谱法之间的联系，使学生更好地理解所有形式的色谱法所涉及的潜在平衡分配原则。

9451493 Brazdil Capillary gas chromatographs are enhancing the basic chemical principles taught in the general chemistry offered both science majors and nonscience majors. The students are using instrumentation practicing chemists use on a routine basis to gain a better understanding of such topics as qualitative identification, calibration and quantitation, identification of chemicals present in household products, Henry's Law, partitioning behavior of substances, and LeChatelier's Principle. Additionally, illustrating the connections between gas chromatography and paper or thin layer chromatography, enables students to better understand the underlying equilibrium partitioning principles involved in all forms of chromatography.
