Supelco SPB ®- 5 capillary gas chromatography column 25305-U

Product Description:

Capillary GC column is also known as open tube column. The carrier gas flows through the central hole and is not restricted throughout the entire column length.

Application: This non-polar universal chromatographic column mainly allows components to be sorted in order of boiling pointElution with slightly improved selectivity, especially suitable for aromatic compounds. USP code: The chromatographic column meets the requirements of USP G27 and G36. Phase: • Combined • Poly (5% diphenyl/95% dimethylsiloxane) Temperature limit: •≤ 0.32mm inner diameter< 2 μm：- 60 ° C to 320 ° C (isothermal or programmed) •≤ 0.32mm inner diameter< 2 μm：- 60 ° C to 300 ° C (isothermal or programmed) • ≥ 0.53mm inner diameter< 2 μm：- 60 ° C to 300 ° C (isothermal) or 320 ° C (programmatic) • ≥ 0.53mm inner diameter< 2 μm：- 60 ° C to 260 ° C (isothermal) or 280 ° C (programmatic)

Application

SPB ®- 5 capillary GC columns are used to detect the quantitative form of nitrogen compounds by chemiluminescence method, which is polar and essentially alkaline. It can also be used as a stationary phase for the determination of deoxynivalenol and deoxynivalenol in grains by electron capture gas chromatography. It can also be used as a stationary phase for the determination of sterols by capillary column gas chromatography.
