Agilent HP-20M 50m, 0.32mm, 0.30u 19091W-015

The Agilent HP-20M (part number 19091W-015) is a fused‑silica capillary gas‑chromatography column using an HP‑20M polyethylene‑glycol (PEG, MW 20,000) stationary phase. Supplied as a 50 m × 0.32 mm column with a 0.30 µm film, it is designed for high‑polarity GC separations of polar analytes such as alcohols, free acids, ethers, glycols, aldehydes and ketones. The column is specified for routine operation in the 60–220 °C range. Agilent/J&W columns are tested to tight QC specifications for column bleed, sensitivity and efficiency to support reliable qualitative and quantitative analysis.

Key Features:

• Format: 7‑inch (standard Agilent format)
• Length: 50 m
• Inner Diameter (ID): 0.32 mm
• Film Thickness: 0.30 µm
• Stationary Phase: HP‑20M (polyethylene glycol, MW 20,000; USP phase G16 equivalent)
• Operating Temperature Range: 60–220 °C

Advantages:

• High‑polarity PEG stationary phase optimized for separation of polar compounds (alcohols, glycols, acids, ethers, aldehydes/ketones).
• Long 50 m length with 0.32 mm ID and 0.30 µm film provides good resolving power for complex mixtures.
• Manufactured and QC‑tested by Agilent/J&W for low bleed, good sensitivity and reproducible efficiency.
• Compatible with established methods that call for HP‑20M/Carbowax 20M chemistry; DB‑WAX is available as a bonded alternative if solvent rinsing or higher stability is required.
