Features 1. Fluorescence Emission Spectroscopy Select a certain wavelength of light to excite the sample and record the functional relationship between the fluorescence emission intensity and the emission wavelength in the sample. The fluorescence emission spectrum is obtained.
2. Fluorescence excitation spectrum selected a fluorescence emission wavelength recording fluorescence emission intensity as a function of the excitation light wavelength, that is, fluorescence excitation spectrum.
3. Time resolution technology;
It can be used to distinguish and separately measure the components of the mixture that have spectral overlap but have different life spans.
The time-resolved fluorescence measurement formula is as follows:
P(t)=P0EXP(-t/Ï„)
Where P(t): fitting exponential function P0: intensity value EXP: exponent operator t: time value Ï„: fluorescence mean time lifetime product application The material composition analysis can be applied to biochemistry, biomedicine, environmental chemical and other departments.
Car Air Purifier
The car purifier is also called a car purifier or a car Air Purifier, which usually consists of a high-voltage generating circuit negative ion generator, a micro fan, an air filter and other systems. Its working principle is as follows: the micro-fan (also known as ventilator) in the machine circulates the air in the car, and the polluted air passes through the PM2.5 filter and activated carbon filter in the machine to filter or adsorb various pollutants, and then After the negative ion generator installed at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage during operation), the air is continuously ionized to generate a large number of negative ions, which are sent out by the micro fan to form an air flow of negative ions to achieve the purpose of cleaning and purifying the air.
