PLOT COLUMNS
Fused Silica Porous Polymer Columns, Particle Trap
PLOT Column Particle Trap
• Includes two Press-Tight® connectors and a 2.5 m column.
• Protects detector and valves; connects between column and detector or valve.
• Eliminates detector spikes and scratches in valve rotors.
The technology used to adhere particles in PLOT columns is excellent; however, it
is still possibile for particles to dislodge when extreme pressure shocks and gas flow
changes occur. This sometimes happens when valve switching or backflushing is used.
In those cases, using particle traps is recommended.
