Hey Jessica, how are you? So great to see you at your new role! Seems like you are getting the hang of Environmental Analytical Chem work! Hehe! Do you use MeOH to extract your salmon samples in PFTE (teflon) tubes? Are your cleanup columns also PFTE? We usually use glass columns for PCB work that we load with silica from scratch!
Hey!! I’m good thanks, how are you? Long time no speak! The tubes aren’t PTFE, they’re PP and I do an extensive alkaline wash of all glassware and plastic before use. I do find I have some small contamination for some of the smaller PFAS I’m working on but only for around 2 out of 30 (and not the most important ones!). Thanks for sharing your methods 😋🫶🏻
Also, I completely get the part when it is hard to film when too many people are working in the lab or you have just too much to do to actually stop and record and explain!
