The equipment purchased through this project was for a laboratory program associated with a course designed for students who are not majoring in the natural sciences. The course, "Chemistry and Crime: From Sherlock Holmes to Modern Forensic Science", is a one semester course designed to teach the fundamentals of forensic science ranging from atomic absorption spectra and paint analysis to infrared spectroscopy and drug analysis to electrophoresis and DNA analysis. The funds were used to purchase equipment for six experiments. (1) Gas chromatography is being used to determine the concentration of alcohol in blood, to determine the identity of accelerants used in arson and to characterize a sample containing a mixture of drugs. (2) High pressure liquid chromatography is being used to separate and identify drugs in suspect samples. (3) The drugs present in samples separated by high pressure liquid chromatography are being identified by infrared spectroscopy. (4) DNA profiles for suspect identification are being obtained by using restriction enzymes and electrophoresis equipment and power supplies. (5) Visible spectrometers are being employed for determining the blood and breath levels of alcohol. These experiment have supplemented a series of experiments previously in place, on a limited basis, with phenomenal success. The various pieces of equipment acquired for the forensic science laboratory are also used in the organic and biochemistry laboratories. A "crime lab" equipped so that the above experiments can be conducted has created an environment to stimulate the interest of the traditional nonscience majors. It has made the study of chemistry more interesting, more challenging and more rewarding. The institution contributed to this project in an amount equal to the NSF funds.

通过该项目购买的设备是为非自然科学专业学生设计的一门课程相关的实验室项目。“化学与犯罪”课程：“从福尔摩斯到现代法医科学”是一门为期一学期的课程，旨在教授法医科学的基础知识，从原子吸收光谱和油漆分析到红外光谱和药物分析，再到电泳和DNA分析。这笔资金用于购买六项实验的设备。气相色谱法被用来测定血液中酒精的浓度，确定用于纵火的助燃剂的性质，以及测定含有混合药物的样品的特征。(2)高压液相色谱法正被用于分离和鉴定可疑样品中的药物。(3)用红外光谱法对高压液相色谱分离的样品中存在的药物进行鉴定。(4)利用限制性内切酶、电泳设备和电源获得嫌疑人DNA图谱。可见分光计被用来测定血液和呼吸中的酒精含量。这些实验在有限的基础上补充了以前进行的一系列实验，取得了显著的成功。为法医学实验室购置的各种设备也用于有机和生物化学实验室。一个配备了上述实验设备的“犯罪实验室”创造了一个激发传统非科学专业学生兴趣的环境。它使化学研究更有趣，更有挑战性，更有回报。该机构为该项目提供的资金相当于国家科学基金会的资金。
