According to statistics from the World Health Organization, the incidence of skin cancer in the United States is close to 20%, which means that on average, 1 in 5 people will get skin cancer once in their lifetime, and this number is still rising year by year. The high incidence of skin cancer is directly related to excessive UV exposure.
The spectrum area of the portable ultraviolet index detector covers UVB and UVA. The system can automatically perform automatic scanning from 290nm-400nm, and accumulate and store data at 1, 2, or 5nm intervals. Combined with the solar radiation and erythema constant (modifiable) programmed into the software, the MPF (monochromatic protection factor) of each selected wavelength is determined and used in the calculation of the SPF value. Using the pipette provided with the system, liquid, milky and gel-like samples can be applied to Transpore Tape or other substrates in a small amount of "dabs" or "spots". The substrate is placed on an open metal frame. Apply the sample gently and evenly to an area exceeding 1250px2 at an amount of 2μl/cm2, which is equivalent to in vivo testing.
Scope of application:
The sun protection factor analyzer adopts the latest optical test system, with precise optical sensors and unique high-compatibility analysis software, and integrates multi-industry test verification system architecture, which can quickly and accurately obtain the material's UVA, UVB, UPF and other sun protection index analysis Indexes, in order to guide the development of anti-ultraviolet properties of materials and to quickly verify the anti-ultraviolet properties of materials, and to digitize and visualize the evaluation of anti-ultraviolet properties of materials. The SPF analyzer is widely used in sunscreen products (sunscreen lotion, sunscreen cream, sunscreen spray), sunscreen functional materials (sunscreen functional textiles, sunscreen treatment additives, sunscreen gel), etc.
Instrument features:
1. Covers UVA and UVB spectral regions, spectral range: 290-400nm, wavelength repeatability: 0.25nm, system data cumulative record storage interval 1, 2, 5nm optional, monochrome resolution: 1.66nm, wavelength accuracy ±0.2% .
2. Data acquisition and analysis software: It has the function of calculating and analyzing printing data, with dual output forms of tables and graphics, built-in Boots Star rating calculation mode, cumulative tests up to 36, optional units, automatic display of MPF and absorbance values, and light stability Test function, automatically calculate UVA, UVB, UPF value, critical wavelength value, support FDA UVA in vitro test, with networking function and convenient online help mode.
3. The 125W xenon arc light source provides stable ultraviolet and near ultraviolet radiation, and the high-performance integrating sphere ensures good test accuracy.
4. Software controlled sampling platform: Provides automatic scanning test and timing measurement, software setting test mode, 12 sampling points, automatic continuous test, automatic stop when the test is completed, and save data; it can meet the standard test and long-term lightfastness test.
Finally, the editor recommends a UV sensor used in portable UV index detectors, that is, the UV sensor imported from abroad-GUVA-S12SD, GUVA-S12SD adopts a SMD package (SMD3528), especially suitable for small volume equipment . The output current of the sensor is proportional to the light intensity, and the output of the product has a very high consistency. The sensor has a specific spectral response. This product is mainly for the measurement of ultraviolet rays in sunlight and the intensity of UVA lamps, and is particularly suitable for UVI detection.
