Instrument features and functions

1. Technical features

C-T type dual beam optical structure

Dual monochromator, aberration correction type Chenier Turner deviceThe C-T dual beam optical structure not only solves the problems of stray light and severe secondary diffraction caused by traditional optical paths, but also compensates for coma, which is superior to0.00002%TThe ultra-low level of stray light is the choice for high-resolution spectrometers

In order to obtain highly reproducible and accurate results from a large number of applications, all optical system lenses are coated with high-quality coatingsMaster holographic gratingThe density of UV visible grating lines is1300 pieces/mm; using a four zone segmented fan-shaped signal collection chopper with *, during the operation of the chopper, the signals of the sample and reference are separately separated and corrected by their respective black zone signals, ensuring the most accurate signals of the sample and reference are obtained each time;

This system can reduce the impact of energy drift from the light source and also minimize the effects of temperature changes on solution density and refractive index;

Sensitive detection

High quality photomultiplier tube configuration, wide gain range, fast response, high stability, especially suitable for detecting weak radiation energy;

The dark current determines the maximum sensitivity of the photomultiplier tube and limits its lower limit for detecting weak light signals,Q series unique dark current automatic correction technology, real-time deduction of dark current, sensitive response to weak light signals;

Adjustable bandwidth
