How can I adjust the results from my UV when it changes over time?

18 January 2025 0 6K Report

I measured the absorbance of a compound and as usual, I autozeroed it before using. But I have observed that the autozeroed value when you remove the DI water UV cell from the equipment, it was -0.047A. from -0.047A to -0.040A UV vis, same wavelength changed in just 20 mins. But I already measured all my samples. I do not know how to adjust it. Please advise

Thank you.
