Perfect for microplastics (MPs) analysis using Pyrolysis-GC/MSNEWUltra ALLOY (UA) MP column kit

This product is a high-resolution column kit consisting of a precolumn (UAMP-1M-1.0F) and a separation
column (UA5-30M-0.5F) of different polarities and film thicknesses.

Features of UAMP column kit
1. Improved peak separation with precolumn
For the 12 commonly used polymers*1, pyrolyzates of eachpolymer can be analyzed with good separation and peak shape.

2. Precolumn helps reduce column contamination
Periodic replacement of the precolumn maintains the performanceof the separation column since high boiling contaminants are
retained in the precolumn.

3. Connectivity to a Multi-Functional SplitlessSampler

UAMP column kit(Precolumn and separation column)

Connecting a Multi-Functional Splitless Sampler (MFS-2015E,Frontier Labs) between the precolumn and separation column
allows splitless pyrolysis and backflushing.

Connection diagram
The connection of the UAMP column kit differs depending on whether MFS-2015E is used or not (seefigure below). When MFS-2015E is not used, connect both columns using the UA connector. When using
the MFS-2015E, a specifically designed splitter is used to connect the precolumn and separation column.
The splitter and the UA connector can be easily attached or detached due to the mechanical flexibility,abrasion resistance, and impact resistance of metal capillary columns.

SplitterImproved separation and reduced column contamination by precolumn
By connecting a precolumn (UAMP-1M-1.0F) to a separation column (UA5-30M-0.5F), peak separation can be achieved(see figure below). High boiling compounds are retained in the precolumn, reducing contamination of the separation
column. Also, periodic replacement of the precolumn will extend the life of the separation column.
