( Brand: Agilent J W ), ( Manufacturer Part Number: DB-17MS ), ( Type: Chromatography Column ), ( Country/region Of Manufacture: United States )
The DB-17ms Agilent Scientific GC Column 122-47 is a high-performance, fused-silica capillary column designed for use in gas chromatography (GC) applications. This particular model has a length of 30 meters, an inner diameter of 0.25 millimeters, and a film thickness of 0.25 micrometers.
The DB-17ms column is coated with Agilent's DB-17ms stationary phase, which is a highly polar, bonded phase that exhibits excellent thermal stability and resistance to degradation. This stationary phase is composed of a unique blend of dimethyl-polysiloxane and cyanopropyl-phenyl-polysiloxane groups, which provide excellent separation efficiency for a wide range of compounds, particularly those that are polar or ionic in nature.
The DB-17ms column is also characterized by its high linear velocity, which allows for fast analysis times, and its low bleed, which minimizes the risk of column contamination and ensures accurate and reproducible results. This column is also suitable for high-temperature GC applications, with a maximum operating temperature of 350 C, and can be used with a variety of GC detectors, including flame ionization detectors (FID), mass spectrometers (MS), and others.
In summary, the DB-17ms Agilent Scientific GC Column 122-47 is a high-performance, fused-silica capillary column that is coated with Agilent's DB-17ms stationary phase. It is suitable for a wide range of GC applications, particularly those that involve polar or ionic compounds, and is characterized by its high linear velocity, low bleed, and high thermal stability. This column is a valuable tool for analytical chemists and chromatographers who require high-resolution, accurate, and reproducible separation results.
