    The Palm-SPEC Spectrophotometer combines a Palm-size PC with a miniature spectrophotometer to create a system with a footprint of 4" x 7". This system, loaded with touch-screen software, provides the general laboratory with a low-cost, easy-to-use and accurate spectrophotometric instrument with a 370-950 nm spectral range. The Palm-SPEC can display and log real-time Concentration, Absorbance, and %Transmission values as well as graphical spectra in ~1 second. The Palm-SPEC comes with a Compaq Aero 2150 Color Palm-size PC pre-loaded with OOIPS2000 Spectrometer Operating Software and the Microsoft Windows CE 2.11 operating system. The spectrophotometer consists of this company's S2000 Minature Fiber Optic Spectrometer, a tungsten bulb, violet LEDs and a sampling chamber for 1-cm square cuvettes.

    The Palm-SPEC uses a 2048-element linear CCD-array detector, which is installed inside of a miniature optical bench with a 600 line/mm grating. This design yields 2048 wavelengths simultaneously over the 370-950 nm spectral range and has an optical resolution of ~2.0 nm FWHM, stray light of <0.05% and photometric linearity of ~99.9%.

    The OOIPS2000 Spectrometer Operating Software designed for Windows CE is operated by the stylus or the touch of a finger. To obtain data, a user places a sample in the holder, selects a previously saved experiment procedure and touches a button to take a scan. The 2.4" x 3.2" high-resolution Thin Film Transistor then displays the Wavelength, Absorbance, Concentration and %Transmission values and a real-time spectrum in ~1 second.

    Method saving allows the user to set and lock experimental procedures. The security feature tracks users and a QC-watch feature monitors system performance, logs outcomes and presents a diagnosis to ensure the integrity of the data and automatic sample naming.

    The Compaq Aero 2150 has 16 MB of RAM. The Palm-SPEC comes with an extra docking cradle, which the user connects via an RS-232 port to any desktop or portable PC with Windows 95/98 or NT. The Palm-size PC can also be used independently of the spectrophotometer. Attach modems (for e-mail or the Internet), cellular phones, digital cameras or any other RS-232 serial device to its serial port. The industry standard infrared port (IrDA) provides wireless connectivity with PCs, printers and other instruments, and the expansion slot allows compatibility with many memory, pager, and I/O cards.
