Why am I getting Empower peak purity angle values higher than peak threshold values for a pure standard? - WKB10800

Article number: 10800

SYMPTOMS

    Empower peak purity angle values are higher than peak threshold values for a pure standard.

ENVIRONMENT

    Empower peak purity Pure standard.

CAUSE

In the Empower Calculating PDA peak purity help menu, it says:

If possible, do not use the shortest wavelengths (190 to 210 nm) within the available wavelength range as they can contribute more noise and variability.

FIX or WORKAROUND

Set the processing method purity start wavelength at 205 nm or above to eliminate some of this noise variability.
