Overview

Quasi dual beam UV visible spectrophotometer $r $n features automatic light seeking and positioning! $r $n truly enables users to freely change lights! There is no need to disassemble the instrument casing. The deuterium lamp and tungsten lamp are both externally replaceable, so there is no need to worry about data instability caused by the light not hitting the access slit after changing the lamp. As long as the light is installed on the dimming path without manual intervention, the instrument will automatically find a better position, more accurate and stable! The main features of $r $n are: $r $n1. The designed optical system, 1600/mm high-performance holographic grating, and * high-performance receiver ensure excellent performance indicators of the instrument. $r $n2. Import

TU-1901 Host Part Operation Interface
DNAProtein measurement scheme one 260nm 280nm measurement scheme two 260nm 230nm

The automatic measurement of DNA/protein mainly involves measuring the absorbance at the points of 260nm/280nm/230nm/320nm, and obtaining the concentration of DNA and protein according to the calculation formula.

Quantitative measurement - By inputting known X and B values, the content of unknown samples can be measured

quantitative measurement

For quantitative analysis of samples, multiple standard samples (two or more) can be used to establish absorbance concentration curves at different wavelengths, and the unknown sample concentration can be obtained from these curves.

Multi wavelength testing - refers to the measurement of absorbance/transmittance of a sample at multiple wavelengths

Spectral scanning - the sample needs to draw a large absorption peak within a certain wavelength range,

Automatically provide peaks and valleys of unknown samples (qualitative analysis)

Time Scan——Dynamics measurement, also known as time measurement, refers to the process where users set wavelength points based on their own samples and scan the sample solution within a certain scanning time range at regular intervals
Measure absorbance or transmittance at scanning intervals, or convert absorbance to concentration by inputting concentration factors.
Can perform time scanning to set single wavelength absorbance or transmittance, and establish absorbance (or transmittance) - time curve
