    摘要: Embodiments generally relate to detection of end of service life for respirator filter cartridges for organic vapor(s). Typically, detection of end of service life might use a competitive UV absorbance-fluorescence approach. Thus, a sensor that emits light upon application of UV may be placed within the cartridge, with a UV lamp and a light detector directed at the sensor. In some embodiments, a plurality of corresponding sensor and UV lamp and light detector might be used. Typically, the light level emitted by the sensor(s) might be used to estimate effective end of service life.

    摘要: The disclosure relates to a microarray reader that includes a light source which emits light and beam shaping elements positioned near the light source to direct the light. The microarray reader further includes a microarray that is at least formed of an optical substrate and a reaction chamber in contact with the optical substrate. A buffer solution is encapsulated by the optical substrate and the reaction chamber and a holder aligns the microarray relative to the light source such that when light hits the buffer solution molecules in the buffer solution are excited to emit fluorescent light. A temperature control component is thermally engaged with the holder such that the temperature control component adjusts the temperature of the buffer solution. The microarray reader further includes a sensor that receives the fluorescent light emitted by the excited molecules in the buffer solution to generate a signal.

    摘要: A method and apparatus for determining the concentration of one or more microbes in a sample is provided. This method involves filtering a sample through a filter inside a sample tube to retain the one or more microbes on the filter. The resulting filtrate, which contains or produces adenosine triphosphate, is passed through the sample tube and enters the reporter region. In the reporter region, the adenosine triphosphate in the filtrate comes in contact with a transparent porous matrix, which includes a luciferin-luciferase complex. The adenosine triphosphate interacts with the luciferin-luciferase complex to provide light response, which is measured by a detector. The light response is compared with a calibration curve to determine the total concentration of one or more microbes in a sample.

    摘要: A microarray reader (500) includes a light source (501) which emits light and beam shaping elements (502) positioned near the light source (501) to direct the light. The microarray reader (500) further includes a microarray (504) that is at least formed of an optical substrate (505) and a reaction chamber (506) in contact with the optical substrate (505). A buffer solution (507) is encapsulated by the optical substrate (505) and the reaction chamber (506) and a holder (508) aligns the microarray (504) relative to the light source (501) such that when light hits the buffer solution (507) molecules in the buffer solution (507) are excited to emit fluorescent light. A temperature control component (509) is thermally engaged with the holder (508) such that the temperature control component (509) adjusts the temperature of the buffer solution (507). The microarray reader (500) further includes a sensor (510) that receives the fluorescent light emitted by the excited molecules in the buffer solution (507) to generate a signal. The microarray reader (500) provides a simple and low-cost solution to overcome the drawback of improper alignment of the microarray (504) on the temperature control component (509).
