YMC-Triart [Metal free column]

YMC-Triart [Metal free column] consists by a double-layered structure: PEEK-lined inner surface and stainless outer tube. YMC-Triart [Metal free column] is suitable for analysis of coordination compouns.

            
Wetted part (liner) PEEK
Outer tubeStainless steel

Features
  • YMC-Triart materials filled in a “metal free” column hardware that consists of PEEK-lined stainless steel tube and PEEK frit.
  • Suitable for analysis of coordination compounds
  • High pressure tolerance guaranteed.
  • Improved Sensitivity on Coordination Compounds Analysis

    Metal coordination compounds which have phosphate group in their structure tend to show poor peak shape by interacting with metal, such as stainless steel column. On nucleotides analysis shown below, better peak shape was obtained with the metal free column.
    The metal free column is effective for highly-sensitive analysis using LC/MS, as well.

    Elimination of sample-metal interaction by optimization of system configuration

    Tubing or HPLC system components could induce peak shape deterioration. The example below shows the comparison of nucleotides analysis on an ordinary HPLC system and a “non-metal” HPLC system. The “non-metal” system consists of a PEEK sample loop, a PEEK injector needle sheet and a PEEK tubing between injector and column. Just by using such PEEK parts, peak shape of coordination compounds can be greatly improved.
