Welch Materials WEL-PEG20M GC Columns

WEL Series Economical GC Columns

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.

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.

General Specifications:

Stationary Phase Composition: Polyethylene glycol 20M (PEG 20M)
