The instrument is designed with full digital output. After 24 bit a / D, the signal is converted to logarithm and zeroed by single chip microcomputer, and the processed result is sent to RS232 interface.

The grating of the instrument is directly fixed on the motor axis of the stepper motor. After sine conversion by the single-chip microcomputer program, the motor is controlled to select the wavelength. The traditional sine bar mechanism is replaced, and the reliability and stability of the system are further improved. The wavelength correction is carried out when the machine is turned on.

The instrument can control the wavelength.

The instrument can carry out automatic spectrum scanning by stopping flow.

The flow cell of the instrument adopts Z-shape design, and the flow cell is treated with constant temperature, so that the noise and drift of the instrument are greatly improved.

The optical path of the instrument adopts double beam design, which further reduces the influence of environmental changes on drift.

The optical path of the product can be adjusted by changing the flow cell and the corresponding system parameters. It can be easily converted from analytical to semi preparative or even large preparative.

The product has analog output port.

The product can be controlled by chromatographic workstation through RS232 interface.
