Instrument setting for absorbance / transmittance measurement
20
①
Set the instrument in the same way as measurement using cuvette.
②
Warming up the light source in the same way as measurement using cuvette.
③
Open the SpectraSmart software, and then open the shutter, slide the side of the
cuvette holder and set the reference film or make air as reference spectrum
