Photometric Mode

  • In this mode, the absorbance (Abs) (or transmittance (%T)) at a specific wavelength can be easily measured.
  • The factor (K) value can be set to allow a simple quantitative test (C = K × A) on a sample to be performed making it possible for absorbance (Abs) measurement.
  • Up to 8 wavelengths can be set, and the absorbance at each wavelength is measured automatically.
  • Automatic analysis for up to 7 samples is possible using the multi-cell holder.

Quantitation Mode

  • It is a mode that can measure and manage the calibration curve by utilizing the multi-cell holder.
  • Quantitative analysis for a sample of interest can be performed using a calibration curve made by up to 7 concentrations of the sample.
  • Four types of calibration curves including linear (zero-crossing), linear, quadratic, and cubic types are provided.
  • Accurate calibration curve can be created with the values measured repeatedly for a maximum of 5 times.

Spectrum Mode

  • This mode allows the user to check the spectrum of the desired wavelength band.
  • Absorbance (Abs) and transmittance (%T) data can be switched using a shortcut key.
  • Automatic spectrum analysis for up to 7 samples (excluding the reference sample) is possible.
  • This mode includes the functions to zoom in the section and to find the Peak/Valley location of the spectrum.

Kinetic mode

  • This mode allows the user to check the change in absorbance (or transmittance) over time at a specific wavelength.
  • This mode is measured at regular intervals, and the minimum interval that can be set is for 1 second.
  • This mode’s progresses during the measurement is displayed, and 24-hour measurement is possible.
  • The changes in the absorbance of 7 samples can be obtained automatically.
