Supel QuE Z-Sep Sorbents for QuEChERs from Sigma Aldrich

Sigma Aldrich introduces Supel QuE Z-Sep sorbents for QuEChERs.  QuEChERs is a solid phase extraction (SPE) technique for sample preparation.  New Z-Sep and  Z-Sep+ sorbents are demonstrated here to extract more fat and pigment than traditional PSA /C18 phases while showing greater analyte recovery and greater reproducibility. Z-Sep sorbents are inexpensive, safe and easy to use zirconia-coated silica particles for the analysis of hydrophobic analytes in fatty matrices.
