GL Sciences’ InertSep SPE products contain sorbents and are created using the same advanced silicas and bonding technologies like those used to create Inertsil HPLC packings. Therefore, InertSep SPE cartridges and 96-well plates show exceptional purity, excellent reproducibility, high recoveries/low non-specific binding, low- to non-existent backgrounds from reagents used to manufacture the column housing, and rigid durability over a wide pH range.
