Portable uv vis spectrophotometer
1. Photometric measurement: It is convenient to measure the absorbance of the sample at the specified wavelength,
Transmittance. Fixed-point test can measure up to 10 wavelengths at the same time;
2.Quantitative measurement: automatically establish a standard curve, first-order \ first-order zero-crossing,
Second- and third-order curve fitting, single-wavelength correction, dual-wavelength correction, and three-point method are optional; standard curve can be stored and recalled;
3. Qualitative measurement: scanning speed of 3500nm / min, many methods of spectrum processing, including: scaling, smoothing, filtering, peak and valley detection, etc .;
4.Kinetic measurement: calculation of enzyme kinetic reaction rate. Various map processing methods such as scaling, smoothing, filtering, peak and valley detection, and derivative are available for your choice;
5.DNARNA, protein test function, automatically calculate the sample ratio and concentration.
