Shinwa ULBON HR-Thermon-HG, 0.53 mm ID x 15m - ULBONHRTHERMONHG05315

ULBON HR-Thermon-HG Polyimide Coated Fused Silica GC Capillary Column

Gas Chromatography Column for Special Purpose - Organic Mercury (Methyl and Ethylmercury) and Tributyltin Analyses

Shinwa Chemical Industries Part Number: ULB-00090-722

Column Specifications:

The ULBON HR-Thermon-HG is the optimum column for analyses of organic mercury compounds subject to regulation, as well as harmful tributyltin compounds used as antifouling agents for fishing nets and in ship bottom paints.

In analyses of TBTC (tributyltin chloride) and alkylmercury compounds, the use of packed column results in poor separation reproducibility due to the adsorption of sample materials.

The ULBON HR-Thermon-HG displays only extremely low levels of sample adsorption, thus enabling good quantitative reproducibility and high sensitivity analyses. In particular, the ULBON HR-Thermon-HG displays superior separation abilities in analyses of tributyltin chloride in comparison with packed columns due to the almost complete absence of decomposition and adsorption phenomena.

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.
