  • Patent number: 9260740
    Abstract: The contamination of foodstuffs, additives, cosmetics, pharmaceuticals and the like by undesirable micro-organisms is threat to public health. On occasion, the level of bacteria that conventional testing techniques are designed to look for is so low that the test result for the bacterium is “negative”. However, the bacterium although present in un-detectably small amounts may multiply under the right conditions and given the shelf life of the product, may be able to recover to an extent whereby public health is threatened. This problem is alleviated by the provision of micro-organism testing apparatus comprising (a) an incubator, and (b) a multi-compartment resealable container provided with or adapted to receive a growth medium in one compartment and having a growth medium additive in another compartment, the compartments being separated by a barrier whose removal or puncture will expose the medium to the additive.

Silver quantum clusters-embedded OTBN are highly luminescent. Since the quantum clusters are embedded in the matrix, they are highly stable over a long period of time. The composition described here is utilized in the form of a device for ‘visible/ultraviolet light color change-based detection’ upon passage of water through a water purification device. Upon interaction with ions present in water, luminescent silver clusters undergo chemical transformation to Ag2S nanoparticles. The transformation is reflected in the form of visible color change (from pink to black) and luminescence quenching (from red emission to negligible luminescence).

    Abstract: The invention is directed towards methods and compositions for identifying the amount of hydrofluoric acid in a buffered oxide etching composition. In buffered oxide etching compositions it is very difficult to measure the amount of hydrofluoric acid because it has varying equilibriums and it is toxic so it hard to handle and sample. When used to manufacture microchips however, incorrect amounts of hydrofluoric acid will ruin those chips. The invention utilizes a unique method of spectrographically measuring the hydrofluoric acid when in contact with added chromogenic agents to obtain exact measurements that are accurate, immediate, and safe.

  • Patent number: 8936754
    Abstract: There is provided a high-accuracy automatic analysis device achieving both of measurement in a wide concentration range and high sensitivity at a low concentration. The signals of a plurality of wavelengths ?1 to ?12 where the sensitivity of light absorption caused by fine particles is high from a light source 40 are converted to absorbances by a spectroscopic optical system (detector) 41. The absorbances are converted to a secondary parameter from in which a noise component is cancelled by using a previously-defined conversion table 54, so that a concentration of a measured material (predetermined component) is calculated by an operation unit (calculating means) 53 based on the secondary parameter. Thus, analysis being resistant to the noise even at the low concentration can be achieved in a range up to a high concentration.

  • Patent number: 8932874
    Abstract: The invention is directed towards methods and compositions for identifying the amount of ammonium acid in a buffered oxide etching composition. In buffered oxide etching compositions it is very difficult to measure the amount of ammonium acid because it has varying equilibriums and it is toxic so it hard to handle and sample. When used to manufacture microchips however, incorrect amounts of ammonium acid will ruin those chips. The invention utilizes a unique method of spectrographically measuring the ammonium acid when in contact with added chromogenic agents to obtain exact measurements that are accurate, immediate, and safe.
