SENSITIVIT Y iN ITS PUREST FORM Sensitivity The Oasis mixed-mode sorbents, which are all built upon the unique water-wettable Oasis HLB copolymer, provide dual modes of retention, enabling greater cleanup selectivity and sensitivity for both acidic and/or basic compounds—even if the sorbent in the wells runs dry. An example of this outstanding sensitivity can be seen with the Oasis μElution plate. This product employs a patented design to concentrate a sample up to 15x without requiring evaporation or reconstitution.

SENSITIVIT Y iN ITS PUREST FORM Recovery Variable recoveries hinder method performance and result in costly retesting, which reduces laboratory productivity. Oasis products use a polymeric sorbent that provides consistent retention and capacity—even if the sorbent dries out. Effect of Drying on Recovery (Oasis HLB Versus C18 Sorbents) impact of drying on Oasis HLB sorbent No High, consistent recovery with Oasis HLB sorbent C18 Cartridge (100 mg) Drying Time Drying Time Quality Waters detailed process design and stringent quality controls have established a new standard in batch-to-batch and lot-to-lot...
