12 Position PPM

12 Position Positive Pressure manifold  : all positions are individually restricted to provide even pressure to each column.
 Even flow can be maintained if you are using one or all positions.

Benefits:
* High affinity and Selectivity 
* Lowered quantification limits
* High Re-productivity and repeatability 
* Robust Materials 
Applications :
* Sample Preparations 
* Perfect Clean-up
* Selective extraction
* Trace analysis 
* Enrichment 

Regulated flow from 0 to 50 mL/min.  Full flow mode for column drying

Accommodate many column sizes 

12PPM - 1mL, 3mL, 6mL, 10mL or 15mL column

Collect rack options

Standard trays for collecting into

16mm or 13mm vials.  Custom trays upon request

Positive Pressure from Nitrogen or Air

Positive pressure gives precise results run-to-run and operator-to-operator.  Use nitrogen or air, as necessary for your method.
