SP-2331 GC-MS Columns for Dioxins
Model 24257 - SP-2331 Capillary GC Column
L × I.D. 30 m × 0.25 mm, df 0.20 μm (Supelco)Application: A highly polar cyanosiloxane column specially tested for analyses of dioxins, specifically tetrachlorodibenzodioxin (TCDD) isomers. Because the phase is stabilized, it has a maximum temperature slightly higher than non-bonded cyanosiloxane columns
USP Code: none
Phase:
• Stabilized
• Proprietary
Temp. Limits:
• Subambient to 275 °C (isothermal or programmed)
