Food

This is an example of the analysis of food dyes. By using ultra-fast scan mode, the time needed for routine spectral checks can be shortened. The 350 nm to 900 nm region can be measured at 1 nm intervals in approx. 4 seconds.

Pharmaceuticals and Life Sciences

This is an example of the analysis of λDNA. Trace quantities (on the order of a few µL) can be measured by combining the instrument with Nano Stick and TrayCell®. Using TrayCell, a calibration curve for 4 µL of λDNA was obtained in the range between 25 ng/μL and 500 ng/μL.

Chemistry

Materials can be confirmed quantitatively by using LabSolutions UV-Vis and color measurement software.
LabSolutions UV-Vis color software shows the chromaticity diagram of the XY color system or Hazen color.
