trouble with the spe cartrige bad weight
Posted: Thu May 08, 2014 9:16 pm
Hi to everybody,
I'm confused about how to choose the right bed weight of a spe cartrige.
My sample is 10 ml and my analyte (pestiside) consantration is between 5-35 ppm (it is not an original wastewater, it is synthetic). I tried different cartriges (C18, 6ml, 350mg), (C18, 6ml, 500mg) but the recovery of my analyte was too low. I thought that something is wrong with my cartrige .And also I'm not clear about how to choose correct cartrige.
Can you explain me please,
I look forward to your comments.
