Gas Chromatographic Column

WM Series High Performance GC Column

WM series of capillary columns adopt strict technique and performance detection with strength in super inertness, low loss, high column efficiency, high selectivity, stable reproducibility and long lifetime.

(1) Super Inertness and Low Loss GC/MS Column

• The unique surface deactivating technique ensures the super high inertness of column, and the peak type of separation component is sharp and symmetrical.
• Unique bonding and cross-linking technology allow the column to keep a low loss level at higher temperature with good stability and long lifetime.

(2) Exceptional lot-to-lot reproducibility

• The consistency of column inertness and superior inter-column reproducibility can be guaranteed by mixed standards samples test.
• Higher detection sensitivity and more accurate analysis results.

(3) Cases of Excellent Performance of WM Column

Determination of 37 fatty acids:

Welch has released dedicated columns for 37 fatty acids with excellent separation performance and reproducibility. Benefited from the optimized method, the analysis time can be greatly shortened without losing the resolution and the customer's analysis cost can be saved.
