Guard Column Cartridge
保护柱芯
Dirty extracts from plasma, food or soil can shorten an analytical column's life quickly. Placed between injector and column, this 1–2 cm cartridge uses the same packing as the main column, in the same or slightly larger particle size. Extra volume is small, pressure adds little when clean, and the reusable holder accepts replacements as the matrix demands.
