Agilent DB-1 100m, 0.25mm, 0.5um, 7inch 122-10AE

The Agilent DB-1 (catalog 122-10AE) is a fused‑silica capillary GC column coated with a non‑polar 100% dimethylpolysiloxane (DB‑1) stationary phase. It is configured as a 100 m, 0.25 mm ID column with a 0.5 µm film in a 7‑inch cage format and is intended for general‑purpose gas chromatography and GC–MS separations of nonpolar to moderately polar volatile and semi‑volatile compounds. The column supports routine and higher‑temperature analyses within Agilent’s specified operating range.

Key Features:

• Stationary phase: DB‑1 (100% dimethylpolysiloxane).
• Length: 100 m.
• Inner diameter (ID): 0.25 mm.
• Film thickness: 0.5 µm.
• Format: 7" cage (7‑inch).
• Operating temperature range: approximately -60 °C to 325/350 °C (manufacturer listed limits).

Advantages:

• Nonpolar DB‑1 phase provides broad, general‑purpose separation performance for volatile and semi‑volatile organics, suitable for GC and GC–MS workflows.
• Long 100 m length with 0.5 µm film increases resolving power for complex mixtures and improves retention of higher‑boiling analytes (inferred from confirmed length/film specs).
• 7‑inch cage format and standard 0.25 mm ID ensure compatibility with common Agilent column hardware for straightforward installation.
• Wide rated temperature limit enables routine low‑temperature work and elevated‑temperature separations when needed.
