S.G.E. Capillary Column [High Separation Ability]

S.G.E. Capillary Column [High Separation Ability]

Capillary columns, an essential item for GC and GC/MS analysis.

At S.G.E., we have added the maximum bleed amount of the column and the minimum theoretical plate number to our inspection items, and we are implementing more rigorous testing methods for each individual column (general columns) than before. By reducing bleed, we keep the baseline rise low and minimize detector contamination. By setting the minimum theoretical plate number (plates/m) in our inspection standards higher than before, S.G.E. offers columns with higher separation capabilities.

J&W Scientific Capillary Column

J&W Scientific Capillary Column

Capillary columns are essential items for GC and GC/MS analysis. They are recognized worldwide as an "industrial standard" in the industry.

Founded in 1975 by several scientists, J&W Company has continued to research "separation" for many years. Since then, it has dedicated itself to the manufacture of fused silica capillary columns, establishing its position as a leading company in this field. Today, under Agilent Technologies, it is recognized worldwide as an "industrial standard" in the industry.

Selection of Capillary GC Columns for Residual Solvent Analysis

Selection of Capillary GC Columns for Residual Solvent Analysis

The use of solid-phase microextraction (SPME)! An excellent analytical method that replaces traditional headspace analysis.

This document presents the results of residual solvent analysis using both the conventional direct injection method and the economical solvent-free high-speed SPME method. SPME is a technique that eliminates the costs and hazards associated with the use of organic solvents, allowing for the high-precision extraction of analytes over a wide concentration range under consistent sampling conditions. We compare three columns equivalent to those described in both EP and USP for the analysis of 60 out of 61 solvents (those detectable by GC/FID), and provide descriptions of these columns. We encourage you to read it. [Included Items (Excerpt)] ■ Column names from USP and EP and their equivalents from Supelco ■ Interactions between the stationary phase and the analyte ■ Interactions between the stationary phase and residual solvents ■ Retention times and elution order of Class I residual solvents on the EquityTM-5, SUPELCOWAXTM 10, and OVI-G43 columns ■ Retention times and elution order of Class II residual solvents on the EquityTM-5, SUPELCOWAXTM 10, and OVI-G43 columns *For more details, please refer to the PDF document or feel free to contact us.
