Balance / Gas Chromatography Laboratory
The Balance/GC Laboratory has 8 analytical balances with tolerances of +/- 0.2 mg. These are used in all chemistry courses. The balances are calibrated and maintained twice each year by an external vendor. There are also six Gow-Mac gas chromatographs in the laboratory. These instruments are used in the General Freshman Laboratory. The gas chromatographs are equipped with PC interfaces using netbooks, Vernier instrumentation amplifiers, and Vernier LabQuest Mini interfaces. LoggerLite is used to acquire and display gas chromatographic traces. LoggerPro is also available via a site license. Hardcopy analog plotters are also connected to each gas chromatograph. Wireless internet service is available in this lab (as well as throughout the building). The gas chromatographs are inspected and tested each semester by the instrumentation technician.
