Shinwa ULBON HR-20M, 0.5 µm, 0.32 mm ID x 25m - ULBONHR20M0503225

ULBON HR-20M Polyimide Coated Fused Silica GC Capillary Columns

Gas Chromatography Capillary Column for General Purpose

Shinwa Chemical Industries Part Number: ULB-00053-716

Column Specifications:

The capillary column performs very higher separation than the packed column because of the small
diffusion and good permeability of the sample. The fused silica capillary column coated polyimide resin on the outside of tubing was developed in around 1980. The inert surface and flexibility of fused silica tubing lead to high performance separation and easy handling. 

ULBON HR Series

“ULBON” is a generic name of the Shinwa capillary columns.
“ULBON HR” is a generic name of the Shinwa capillary columns with chemical bonding layer.

Shinwa provides ten types of stationary phases for general analysis and each analytical purpose, as an ULBON HR series. The columns are also available in various lengths, inner diameter and the film thickness of stationary phase for your requirement.

Characteristics

The inert inner surface of the column results in high quantitative analysis.
The adsorption point of the inner surface of the column has been completely removed by a rigid
treatment. Therefore, free acid and free amine which are easily adsorbed are eluted without interaction with the active surface.

No exfoliation and bleeding of stationary phase lead to high sensitive analysis.
In HR series column, the rigid chemical bonding is treated on the surface, therefore there is almost no exfoliation and bleeding of stationary phase. No bleeding from the column results in the high sensitive analysis.

The maximum temperature is higher than that of ordinary WCOT column.
The maximum temperature of HR-20M (correspondence to PEG-20M) is 240 °C and HR-silicone
series are 330 °C (except HR-1701 and HR-17). The maximum temperature of chemical bond type
column rises about 70 °C compared with the WCOT type.
