Laser flash photolysis instrumentIt is a high-precision scientific instrument used to study the transient phenomena of molecules under light excitation, and has wide applications in fields such as chemistry, physics, biology, and environmental science.

Key performance indicators:

1. Spectral range

The detection range covers 190-920nm, and precise spectral control is achieved through a two-stage programmable monochromator, suitable for transient absorption spectroscopy analysis of liquid, solid, and thin film samples.

2. Time resolution

It has nanosecond level time resolution capability (such as 2-3ns rise time), with a sampling frequency of up to 2.5GS/s, and can capture the dynamic process of rapid photochemical reactions.

3. Sensitivity and accuracy

The sensitivity reaches ± 0.0005AU in pulse mode and ± 0.001AU in continuous mode, meeting the high-precision detection requirements of trace samples.

Development trend:

1. High time resolution

The nanosecond level time resolution capability can accurately capture the generation and decay processes of transient intermediates, providing critical support for chemical reaction kinetics research.

2. Wide spectral range

By using OPO technology, the wavelength of 400-1700nm can be continuously adjusted to meet the detection needs of different molecular systems.

3. Multi functional integration

Integrated transient absorption spectroscopy, emission spectroscopy, and kinetic analysis functions can simultaneously obtain concentration changes and reaction rate information of transient species.

4. Automation and Intelligence

Equipped with data analysis software such as ProData and ProK, it achieves fully automated data acquisition, processing, and simulation, improving research efficiency.
