13 Basic Concentration Measurements—Basic A-%T-CSetting the Wavelength and ModeThe steps for taking measurements in the two modes are similar—the only difference iswhether you measure a standard or enter a factor.Setting the Wavelength and ModeTo set the wavelength and mode1. Press Set nm or any other number key to set the wavelength.2. Enter the wavelength for taking measurements and press Set nm again.3. Press Change Mode until the appropriate measurement mode (Concentration withStandard or Concentration with Factor) appears.Using Conc/Std to Measure ConcentrationIn this mode a standard sample of well known concentration is used to determine theconcentration of samples. The concentration of unknown samples is determinedratiometrically from the measured standard. The measurement can be expressedmathematically asStandard Concentration Sample ConcentrationAbs / %T of Standard Abs / %T of Unknown Samplewhere the standard concentration is precisely known, the Abs/%T of the standard and theAbs/%T of the unknown sample are measured, and the sample concentration is calculated.To use Conc/Std to measure concentration1. If necessary, press Change Mode to switch to the Concentration with Standard mode.If a 6-Position Cell Changer is installed, place the blank in the B position, and thestandard in position 1.58 Orion AquaMate 7000 Vis and Orion AquaMate 8000 UV-Vis Thermo Scientific
