Product Description: How to Translate

Adopting dual monochromators and dual imported photomultiplier tube optical path compensation design. Equipped with * PC software and hardware, the instrument has excellent qualitative and quantitative testing functions. This instrument is used for trace analysis and determination in various fields such as chemistry, drug testing, environmental protection, petrochemicals, medical and health care, and food nutrition.

Main features:
● Independent dual optical system structure.
Adopting real-time monitoring and compensation technology for light sources, the measurement results are stable.
High sensitivity and high signal-to-noise ratio, with an S/N ratio of over 150.
Adopting dynamic 20 bit A/D conversion technology, with a wide dynamic range and good linearity.
Using a standard PC as the hardware environment, the instrument has a low failure rate and strong reliability.
Adopting * window software technology, the data graph processing function is strong and the operation is simple.
● Equipped with audit tracking software.
Using a 150W high-power xenon lamp with strong excitation energy, it produces a continuous light source.
Adopting automatic compensation technology for light sources, the measurement results are stable.

Function:
The PC directly controls the host and processes data, using mouse buttons to comfortably perform a series of operations such as scanning, data analysis, tabulation, and recording.
Using a high-speed A/D converter with 20 bits, it has a large dynamic range and can quickly and accurately measure small changes in the sample.
Software functions:
Filtering: Retrieve peak values; Calculate peak area; Continuous scanning measurement; Quantitative analysis of samples; Draw the standard curve (1-3 times); Calculate the concentration of the tested sample based on the standard curve, save and adjust the spectrum; Graph window processing; Automatically measure S/N ratio, etc.
