Report Variable (Detection Parameters)

Type:

Floating point number

Dimension:

nm

Value range:

190.0 - 900.0

Default:

Start: 190.0 nm; End: 900.0 nm

Related Parameters:

Peak Purity Threshold

Description:

The Peak Purity Start Wavelength and Peak Purity End Wavelength detection parameters limit the wavelength range for peak purity calculations.

Function:

For calculating the Peak Purity Index (PPI) and the Peak Purity Match Factor, only the wavelength range within the values limited by start and end is used.

 Note:

The values 190 nm (Start) and 900 nm (End) are used as defaults. The actually recorded wavelength range is used for the calculation if the recorded range of the 3D field is smaller.
