Main features:
Durable stability: The dual beam optical system and circuit system ensure the long-term stability of the instrument.
Ultra low stray light: Advanced optical systems, low-noise circuit systems, and high-quality optical components ensure that the instrument has ultra-low stray light, making high concentration sample testing more accurate.
Display and operation: Humanized design, the host can perform spectral scanning, and the large screen display shows data, graphics, and curves, making it more intuitive and easy for users to operate.
Easy and convenient replacement of lamp source: The flange seat deuterium lamp structure eliminates the need for special tools when replacing the deuterium lamp, eliminating the need for light path debugging steps during lamp replacement, making instrument debugging and maintenance easier.
Rich optional accessories: various accessories such as automatic six color comparison stand are available for selection, and the instrument measurement function is more extensive.
Optional UV-Solution3.0 working software, capable of conducting various tests (spectral scanning, derivative spectroscopy) and other functions.
Main functions:
Luminescence measurement: Measurement of transmittance, absorbance, and coefficient absorbance at a fixed wavelength.
Spectral scanning: optional scanning speed, optional scanning interval (0.1, 0.5, 1, 2, 5nm), automatic peak/valley detection, spectrum scaling and other functions.
Quantitative determination: Single wavelength method, 1-3 order linear standard curve fitting, can establish standard curves for up to 9 standard sample points.
Dynamics measurement (time scan): Conduct dynamic testing on the sample, with optional testing intervals, and can save nearly 10000 test data points.
UV2800S has four adjustable spectral bandwidths (0.5, 1, 1.8, 4nm).
Supplementary explanation for industry applications:
The UV2800 series is a large screen scanning dual beam. The new optical and circuit system design ensures that the instrument has high resolution, low stray light, persistent stability, and high signal-to-noise ratio. The 1.8nm bandwidth has higher spectral resolution and can meet the requirements of multiple pharmacopoeias. The bandwidth adjustable UV2800S meets the multi-level analysis application needs of users. Computer application software enables more powerful functions for your instrument.
