| Study Title | GC-XLE method development: dSPE and MgSO4 as clean-up for sample preparation |
| Study Type | Untargeted MS anlaysis |
| Study Summary | Compared to using dispersive SPE (dSPE) based on the QuEChERS procedure, we found similar reproducibility using high purity MgSO4 to analyze standard reference material (SRM) of human serum and human plasma samples and slightly higher recovery of targeted chemicals using MgSO4. To avoid contamination by environmental chemicals in solvents and reagents used for QuEChERS, we chose to use high purity MgSO4 to remove water-soluble interferences. |

Collection:
| Collection ID: | CO001857 |
| Collection Summary: | Ethylenediaminetetraacetic acid (EDTA)-treated plasma samples were collected following standard operating procedures. Two samples were randomly selected from archival samples obtained from the Center for Health Discovery and Well Being (CHDWB) cohort of approximately 750 individuals and pooled to complete the test of XLE method development. The original study was conducted under Emory Investigational Review Board (IRB approval No. 00007243) and included both genders and individuals self-identifying as white, black, Hispanic and Asian. SRM1958 are standard reference material of human serum fortified with organic contaminants and were purchased from National Institute of Standards & Technology (NIST). |
| Sample Type: | Blood (plasma) |
