Simultaneous Determination of Two Dyes in Solution

Work through the experiment one stage at a time. Each step has its own page, and the data collected in earlier steps carries forward into the next stage.

Step 1

Determine Dark Current and 100%T Signals

Collect the baseline detector readings that will be reused in the calibration and mixture-analysis pages.

Instrument Controls

Choose a wavelength and setup, then record a measurement.

How Step 1 Works

Measure the detector response with the light blocked to get the dark current, then measure the blank cuvette to establish the 100%T reference for each wavelength.
