I work with an ICS5000 to analyze sugars in foods with a PA10 column Thermo.
Our sequences are 30-40 samples,every 5 samples we put a intermediate standard to control time and area displacements, the analysis lasts one hour each sample.
we observed falls of areas in the intermediate standards regarding the same standar of calibration by 20-30%, this interferes with low results in the samples.
Why is this happening?
Thank you very much!!!!
