Need some help with Method EEA 521.1 for Nitrosamines
Posted: Fri Apr 11, 2025 3:56 pm
Hi,
I am running method EEA 521.1 for nitrosamines and am having trouble with the internal standard not being consistent through the run. I have a directly spiked calibration and check standards that are all within range but when I extract a sample the response will go above the required 30 percent window. Has anyone had these issues?
