Abstract: A portable, battery powered instrument for measuring the amount of material dissolved in a liquid solution employs electro-optic technology based on the Beer-Lambert Law. A sample probe (14) is inserted in a solution to be measured. The results of the measurement are displayed on a display (22). The displayed results are frozen for a predetermined period of time at the expiration of which, the power is turned off to conserve battery power.

Abstract: A monitor for use in sample testing comprises a sample chamber for receiving a vessel containing a light-emitting substance, and an avalanche photodiode for receiving the emitted light and connected to a circuit for measuring the light received by the avalanche photodiode. The use of an avalanche photodiode enables the monitor to be portable and robust and to be included in a portable kit for carrying out hygiene monitoring in the field.

Abstract: Wide-field fluorescent imaging on a mobile device having a camera is accomplished with a compact, light-weight and inexpensive optical components that are mechanically secured to the mobile device in a removable housing. Battery powered light-emitting diodes (LEDs) contained in the housing pump the sample of interest from the side using butt-coupling, where the pump light is guided within the microfluidic flow cell to uniformly excite the specimen. The fluorescent emission from the sample is then imaged using an additional lens that is positioned adjacent to the existing lens of the mobile device. A color filter is sufficient to create the dark-field background required for fluorescent imaging, without the need for expensive thin-film interference filters.

Abstract: An optical fluid tester device for testing a fluid sample in an ampoule includes an ampoule cradle, a radiation source, a radiation detector and an analyzer. The ampoule cradle supports the ampoule. The ampoule with the fluid sample serves as a lens whose focal properties are dependent on the index of refraction of the fluid sample. The radiation source irradiates the ampoule. The radiation detector is located opposite the radiation source so that the ampoule, when supported by the ampoule cradle, lies between the radiation source and the radiation detector. The detector serves to detect the intensity of the incident radiation. The analyzer verifies the composition of the fluid sample based on the detected intensity, which is dependent on the focal properties of the ampoule and is, therefore, indicative of the composition of the fluid sample.

Abstract: Appareil de contrôle permettant d'effectuer des tests sur des échantillons qui comprend une chambre d'échantillon dans laquelle on place un récipient contenant une substance luminescente, et une photodiode à avalanche qui enregistre la lumière émise, que mesure ensuite un circuit auquel la photodiode est connectée. Grâce à l'utilisation d'une photodiode à avalanche, l'appareil de contrôle est solide et transportable, de sorte qu'on peut l'intégrer dans un nécessaire portatif pour effectuer sur place des contrôles d'hygiène.
