Welch Materials have concentrated on GC R&D and production for many years, and each column would be tested strictly before selling with attached column report. Welch columns are characterized by stable properties, high column efficiency and good reproducibility.
Welch GC column can be divided into two types: WM Series High Performance GC Column and WEL Series Economical GC Column, which can meet the analysis requirements of various customers.
Welch also provides services as sample analysis, method development, column recommendation, after-sales support and training for customers. With good product performance and perfect after-sales service system, our GC columns have been widely used in universities, research institutes, pharmaceutical, petrochemical, brewing, environmental protection or other industries.
WM Series High Performance GC Column
(1) Super Inertness and Low Loss GC/MS Column
- The unique surface deactivating technique ensures thesuper high inertness of column, and the peak type of separation component is sharp and symmetrical.
- 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.
Cross Reference
Each of the WEL series of capillary columns has been strictly tested with attached evaluation chromatogram. For high column efficiency and sensitivity, our products are popular among new and regular customers. We can provide sample analysis for customers to ensure the superior performance of columns and various dedicated columns for some test items with higher column efficiency and separation effect, which can help in the qualitative and quantitative analysis.
