- W2085104724 abstract "Handheld computers provide a compact and cost-effective means to log data in the undergraduate chemistry laboratory. Handheld computers have the ability to record multiple forms of data, be programmed for specific projects, and later have data transferred to a personal computer for manipulation and analysis. They are more affordable than notebook computers and are more widely applicable than programmable calculators. This study focuses on acid–base titration experiments that are commonly used in introductory chemistry courses. We wrote an interactive Basic language program that allowed a Palm device to measure pH during the course of a titration, and we used a compatible interface for the data acquisition, which we found to record accurate voltage measurements. After synchronizing the device to a laboratory workstation, the experimental data could be transferred into a spreadsheet file, viewed in graphical form and analyzed. Many other applications of handheld computers in the laboratory are possible with the ability to write individual programs on a handheld device. Therefore, the Palm's size, ease of use, and affordability make it an attractive alternative to previous data acquisition methods for use in the chemical laboratory." @default.
