Polybiphenyldimethylsiloxane capillary GC column 28264-U

Supelco Equity-5 Gas Capillary GC Column Detailed Description:

Application: The Equity-5 gas chromatography column is designed for general use when non-polar chromatography columns are required. Compared to 100% polydimethylsiloxane columns, low phenyl content provides thermal stability.

USP code: This chromatographic column meets the requirements of USP G27 and G36.

Phase:

Bonded

Poly (5% biphenyl/95% dimethylsiloxane)

Temperature limit:

≤ 0.32 mm inner diameter,<2 μ m: -60 ° C to 325 ° C (isothermal) or 350 ° C (programmatic)

≤ 0.32 mm inner diameter, ≥ 2 μ m: -60 ° C to 300 ° C (isothermal or programmatic)

≥ 0.53 mm inner diameter,<2 μ m: -60 ° C to 300 ° C (isothermal) or 320 ° C (programmatic)

≥ 0.53 mm inner diameter, ≥ 2 μ m: -60 ° C to 260 ° C (isothermal) or 280 ° C (programmatic)

The application of Equity-5 gas chromatography column: The Equity-5 gas chromatography column is widely used in weak polarity applications and belongs to a broad-spectrum application column Compared with 100% polydimethylsiloxane, this fixed phase containing a small amount of phenyl is beneficial for improving thermal stability

USP Code: Complies with USP G27, USP G36

Fixed phase: bonded, poly (5% diphenyl, 95% dimethylsiloxane)

Temperature range:

-60 ℃ -325/350 ℃ (0.10 to 0.32mm inner diameter column)

-60 ℃ -300/320 ℃ (0.53mm inner diameter column with a film thickness of 1.5 microns)

-60 ℃ -260/280 ℃ (0.53mm inner diameter column with film thickness greater than 1.5um)

Based on a series of chemical properties such as polarity and boiling point of the compounds entering the chromatographic column, fixed phases have different adsorption and desorption abilities, resulting in the separation of compounds on the chromatographic column. The separation ability of compounds varies among chromatographic columns with different stationary phases

The stationary phase adheres to the inner wall of the capillary in liquid form, and polysiloxane is the most common stationary phase

100% polydimethylsiloxane chromatography column is -1 column

5% phenyl and 95% polydimethylsiloxane chromatography column is -5 columns
