Setting up Internal Standard Correction in Qtegra


Why use an Internal Standard?
• The use of an internal standard (IS) is the most efficient way of correcting for the presence of non-spectral interferences
• Interferences occur when the Physical and/or Chemical composition of the sample is different from the composition of the calibration standards
• This type of interference will manifest itself as either an enhancement or a suppression of the analyte signal
