When it comes to high-quality GC columns, Hewlett Packard is a trusted name in the industry. One of their popular products is the HP-5ms column, which is identified by the part number 19091S-43In this article, we will explore the composition and features of this column, as well as its equivalence to other capillary columns.
What is the HP-5ms Column?
The HP-5ms column is a capillary column designed for gas chromatography (GC) applications. It is made of a (5%-phenyl)-methylpolysiloxane phase, which provides excellent inertness for active compounds. This makes it suitable for a wide range of applications, including the analysis of acidic and basic compounds.
With a length of 30 meters and a diameter of 0.25 mm, the HP-5ms column offers optimal separation efficiency. It has a film thickness of 0.25 µm, which ensures improved sensitivity and mass spectral integrity. The column is housed in a 7-inch cage, making it compatible with various GC systems, including Agilent 5890, 6890, 7820, 7890, 8860, and 8890 series GC systems.
The HP-5ms column is known for its very low bleed characteristics, making it ideal for GC/MS applications. It is bonded, crosslinked, and solvent rinseable, allowing for easy maintenance and extended column life.

Equivalent to USP Phase G27
The HP-5ms column is equivalent to USP phase G27, which means it meets the performance requirements set by the United States Pharmacopeia. This ensures consistent and reliable results across a range of applications.
Benefits of the HP-5ms Column
The HP-5ms column offers several benefits that make it a popular choice among chromatographers. These include:
- Excellent Inertness: The column provides excellent inertness for active compounds, allowing for accurate and reliable analysis.
- Low Bleed Characteristics: The HP-5ms column has very low bleed characteristics, reducing background noise and improving signal-to-noise ratio.
- Wide Compatibility: It is compatible with various GC systems, including Agilent and non-Agilent systems with similar oven sizes.
- Long Column Life: The bonded, crosslinked, and solvent rinseable design ensures easy maintenance and extended column life.
- Improved Sensitivity: The 0.25 µm film thickness of the column provides improved sensitivity, allowing for better detection of analytes.
