| FEATURES |
| ChromPACK GCB/NH2 | GCB: Surface area: 170 m2/g
Partical size: 200-400 mesh
| * ChromPACK GCB&NH2 dual layer SPE column contains GCB (upper layer) and NH2 (lower layer) SPE sorbents |
| NH2 Average partical size: 50 μm
Pore size: 60 Å
Carbon (C%): 5.0%
| * GCB has a strong affinity towards planar molecules, pigments like chlorophyll and carotinoids, sterols commonly in foods and natural products |
| | * NH2 can effectively retains fatty acids, organic acids, some polar pigments and sugars in food matrices |
| ChromPACK GCB/PSA | GCB:
Surface Area: 170 m2/g
Partical size: 200-400 mesh | * ChromPACK GCB/PSA is a dual layer SPE cartridge that contains GCB (upper layer) and PSA (lower layer) SPE sorbents |

some polar pigments and sugars in food matrices |
| | | * Similar to ChromPACK GCB/NH2, but GCB/PSA has more retention for analytes because its PSA in the lower layer contains both primary
