Parameters Tab

All relevant parameters for data collection can be defined in the Instrument panel:

Measurement Parameter​

Specifies parameters that directly affect data acquisition:

Spectral Range​

The spectral range to be measured can be manipulated by following options.

  • Start
    This parameter specifies the lower limit of the spectral range dependent of the x-Axis unit.

  • Stop
    This parameter specifies the lower limit of the spectral range dependent of the x-Axis unit.

Normalization​

The following modes are supported:

  • Counts
    Returns raw energy data.

  • Transmission
    Returns a background corrected spectrum having Transmission units as y-axis units.

  • Emission
    Returns a background corrected spectrum having Emission units as y-axis units.

  • Absorbance
    Returns a background corrected spectrum having Absorbance units as y-axis units.

  • By Formula
    Returns a spectrum based on the formula definition.

Transmission, Emission and Absorbance measurement requires a valid reference!

When measuring an absorbance, emission or transmittance spectrum a valid reference needs to be measured in advance.

Perform Time Scan​

With this parameter activated a new section for setting kinetic measurement parameters is activated.

Perform Time Scan​

Performing kinetic measurements is very similar to the regular spectrum measurement. A kinetic measurement consists of a sequence of regular spectrum measurements acquired with a particular delay time between the measurements. Collected data is automatically saved according to the saving policy. The operator simply has to adjust the additional acquisition parameters Measurements and Interval.

Initial Delay​

This specifies the delay time between pressing the start button and the first measurement. When monitoring a reaction or whenever a delay is required for any operations to be completed before the first measurement is started, this time needs to be adjusted here.

Interval​

This parameter specifies the time between two subsequent measurements.

Interval too small

There is no proof for the interval time being valid before starting the kinetic measurement run. If the time is set too short the next measurement would be started, before the ongoing measurement is completed. In such event the kinetic measurement is stopped showing an error message indicating to adjust the interval time to a more appropriate value as shown in the message.

Total Time​

This specifies the delay time between pressing the start button and the first measurement. When monitoring a reaction or whenever a delay is required for any operations to be completed before the first measurement is started, this time needs to be adjusted here.

Instrument Parameter​

Integration Time​

This parameter controls the length of time the device averages the signal before readout. The longer the integration time, the stronger the signal is recorded.

Bunching​

Please contact your hardware supplier for further details.

Accumulations​

This parameter sets the number of spectra that are averaged before display. A larger the number of spectra average results in a clearer and less noisy the spectrum.

Automatic Measurements​

Dark before Reference​

This parameter set forces the software to always acquire a Dark spectrum before running the Reference

Reference before Sample​

This parameter set forces the software to always acquire a Reference spectrum before running the regular Sample measurement
