Before and after the treatment, the usual method is to check whether the hemodialysis results are sufficient. The dialysate dose monitor (DDM) continuously measures the composition change of used dialysate * 1 through UV light absorption, and determines the dialysis dose. The dialysis dose is displayed on the screen to ensure that the patient has been adequately treated in each treatment. In this kind of optical measurement, deep UV LED has the ability of compact, single wavelength and optional wavelength.

Similarly, applications in other analytical applications in the medical field, such as blood analysis, are also expected.

*Used dialysate returned from the dialyzer, including waste discharged from the patient.

Some substances have the property of producing fluorescence by irradiating ultraviolet rays. As for the detection and analysis of foreign matters in food manufacturing, equipment utilizing this property is also used. Although the wavelength required for fluorescence varies according to the physical object, it is difficult to select the wavelength with conventional UV mercury lamp because the emission spectrum is fixed.

With deep UV LEDs, wavelengths can be selected, and they are expected to achieve analytical techniques that cannot be achieved with conventional light sources. In addition, they have many advantages in food analysis, such as no mercury, no heat generation in the radiation direction, compact and high design flexibility.

Some substances have the properties that enable them to absorb ultraviolet light of a specific wavelength, and the concentration in the gas can be obtained by irradiating the ultraviolet light and measuring the amount of light transmitted. This principle can be used in ozone analysis equipment, as well as TOC (total organic carbon), protein, Sox, NOx, chlorine, etc., and similar principles can be used for analysis.

In order to analyze these items, UV mercury lamp is usually used. However, there are various limitations in size and voltage. By using deep UV LED in the analyzer, miniaturization and low power consumption can be realized.
