Microanalysis Laboratory Contact person for lab facilities: NAME: Hsiupu Daniel Lee PHONE: 765-494-5308 FAX: 765-494-0239 E-MAIL: hdlee@purdue.edu Purpose of lab: The purpose of this lab is to provide elemental analysis services in support of the basic researches within the campus. When time and facilities allowed, we also perform custom syntheses of organic and inorganic compounds upon demand. Description of lab: The lab is located in Rm. 242, Wetherill Building. It has one full time supervisor who is responsible for the equipment and the services, and who is also available to provide expertise and assistance in the area of microanalysis. Usage of equipment: With proper coordination, the equipment is available for use by other Purdue University departments, other Universities, and/or external/outside company research. Policies and rules of use for available equipment: The equipment may be used by undergraduate students, graduate students, post docs, and visiting scientists. The lab supervisor will check out personnel on the use of equipment and review the safety of the proposed project. The user will provide all chemicals and expendables such as crucibles and gases. The cost of modification or upgrade of equipment for a project is the responsibility of the user. The user will also be responsible for repair of equipment damaged by negligence. List & type of equipment available: The main equipment of the lab is a Perkin-Elmer 2400 Series II CHNS/O Analyzer, capable of analyzing carbon, hydrogen, nitrogen, sulfur, and/or oxygen. The lab also has a Perkin-Elmer 240C Elemental Analyzer used for the determination of carbon, hydrogen, and nitrogen. There are several combustion apparatus for the determination of metals, a Corning 250 Ion Analyzer for the analysis of special ions, and two pH-meters for the measurement of pH’s of solutions. The lab has two electronic microbalances which can measure samples down to the tenth of a microgram, and two mechanical microbalances capable of the measuring samples from 19.999 g down to micrograms. Finally, there are some ovens , glassware, and digestion and titration apparatus used for volumetric and gravimetric titration. Is the usage of equipment available for only departmental research or is it available for other Purdue University departments, other Universities, and/or external/outside company research? The services are opened to the Chemistry department as well as all of the other departments on the main campus, the Ft. Wayne campus, and the IUPUI campus. These services are also available to other universities and/or external/outside company research. Policies and rules of use for available equipment (who can use the equipment, cost of equipment, how it is organized, etc.) The lab equipment is not available for use by any person outside our lab. We only accept samples submitted for the analysis of their element contents. Following are the instructions for submission of samples for elemental analysis: Fill out a request form which is also used as a report to you after the analysis has been done. Sample size is 3-7 mg for carbon, hydrogen, and/or nitrogen. Sample sizes are usually larger for other elements, depending on the weight % of those elements in the samples. It is necessary to make an appointment for the analysis of an unstable compound, so that the compound can be analyzed without being delayed. Turnover time is approximately one to two days for carbon, hydrogen, and nitrogen. Other elements take longer time, depending on the schedule. Arrangement is necessary for any special analysis. * Submitted to the Purdue University Materials Consortium on April 28th, 1998, by Hsiupu Daniel Lee.
