    Abstract: A field test-kit for analyzing arsenic concentration in water samples is provided. The kit includes a portable infrared beam photometer for measuring light absorbance in aqueous specimens. An infrared light emitting diode is configured to direct a beam of light through a specimen. A photodetector diode measures the intensity of light passing through the specimen. The photodetector output voltages relate to the light absorbed in the specimen and are displayed on a liquid crystal display screen. The kit is assembled using off-the-shelf electronic and opto-electronic components that have low power requirements. Dry cell batteries or solar cells power the kit. To test for arsenic, molybdenum based chemistries are used to selectively bind and convert arsenates and phosphates in the specimen into molybdenum-blue color complexes. The light absorbance of a specimen with both arsenates and phosphates bound in molybdenum-blue color complexes is compared to that of a reference specimen in which phosphates but not arsenates are bound and converted. The differential light absorbance of the two specimens is used to arrive at a quantitative value for the arsenic concentration in the water sample.

    Abstract: A handheld, portable color measuring device (10) for measuring the primary colors of red, green and blue in a color target (22) and connected to a built-in LCD display (30) or connected to a separate personal computer (38). The color measuring device (10) includes an elongated color measuring probe housing (12). A hollow cone shaped probe tip (18) is attached to one end of the probe housing (12). Inside the probe housing (12) is a battery powered white LED light source (42) connected to a color measurement switch (26). A light pipe (44) is centered inside the probe housing (12) and a portion of the probe tip (18). The light pipe (44) captures the light reflected off the color target (22) and projects the captured light onto a 3 color sensor (54). The light signal is amplified and converted to a digital signal using an A/D converter. The A/D converter is part of a microprocessor mounted on a printed circuit board (56) inside the probe housing (12).

    Abstract: A tiny and portable micro-spectrometer deployable in a bullet-like form that is inexpensive to the point that it can even be disposable is described. The device is based on the micro-spectrometer that uses the Fresnel diffraction principle that allows a tiny implementation with a nanometer resolving power of spectral signal. A bullet-like micro-spectrometer has an integration of a super capacitor as a power source, a charging coil for the super capacitor, an LED or laser diode light source and driver, an analog to digital converter (ADC) circuit, and a telemetry system with antenna string. An LED or laser diode runs in a burst mode to generate deep or vacuum UV to excite target material. When the excited state of target material undergoes a singlet or triplet transition, this transition process yields fluorescence or luminescence which is a material-dependent. The micro-spectrometer senses and uses this spectral emission from material to identify the spectral signature of the targeted material. The data is converted by an ADC and transmitted to a receiving station.
