software function

Wavelength scanning: Full band spectrum scanning from 190nm to 1100nm can be performed on the tested substance, or segmented scanning can be performed

Dynamics testing: Time scanning of the tested substance to timely detect changes in absorbance caused by changes in concentration

Quantitative measurement: By establishing a standard curve, concentration analysis of the measured substance can be performed

Multi wavelength testing: Multiple wavelengths can be set simultaneously to test the absorbance of the tested substance at multiple wavelengths

DNA/protein testing: purity and concentration analysis of DNA/protein using nucleic acid protein testing formula
