Latest Patents

One of Araya's latest patents is a Continuous Gas Analyzer. This device features a standard gas introduction passage and an air inlet port positioned downstream and upstream of a dehumidifier, respectively. It measures zero gas and span gas in dry states, subtracting a moisture interference value from the sample gas measurement. This innovative approach allows for quick calibration, reducing the size of standard gas cylinders and miniaturizing the overall device.

Another significant invention is the Apparatus for Non-Dispersive Infrared Analyzer. This apparatus utilizes an infrared light beam emitted from a source that alternates between a sample cell and a reference cell through a rotating chopper. The design ensures that the infrared light beam is emitted for equal durations to both cells, allowing the analyzer to gather twice the information about gas concentration compared to conventional devices.
