Overview
The QIWEI WFH-203B camera obscura UV analyzer is composed of a quartz Glass UV lamp and a filter, providing UV light sources with two wavelengths of 254nm and 365nm. The Illuminant can be used for experiments after being filtered by the filter, and the two Illuminants can be used alone or mixed at the same time. The instrument has a simple and lightweight structure, strong versatility of parts, and convenient use and maintenance.
Features
1. Composed of quartz Glass UV lamp and filter, providing 254nm and 365nm wavelength Illuminant
2. Illuminants can be used alone or mixed at the same time
3. Built-in ordinary fluorescent lamp, providing illumination for chromatography plate pointing and positioning
4. The whole machine is simple in structure, lightweight, and has strong parts versatility
5. Easy to use and maintain
Principle
The instrument produces ultraviolet light with wavelengths of 254nm and 365nm through a quartz ultraviolet lamp, filters the color of the filtrate and irradiates the sample. The fluorescent substances in the sample generate fluorescence under ultraviolet excitation, and are analyzed and detected by observing the fluorescence phenomenon.
Applications
Scientific experiments, production research, dyestuff coatings and rubber, petrochemistry, Spinning & weaving chemical fibers, grains, oils, vegetables and food, public security certificate identification
Steps
1. Connect power supply (AC220V +/- 10% 50Hz)
2. Select the UV light source to be used (254nm, 365nm or mixed)
3. Place the sample in the observation area
4. Turn on the corresponding Illuminant for observation and analysis
5. Turn off the power after use
