( Brand: Agilent ), ( Manufacturer Part Number: PL1110-1520 ), ( Part Type: Guard )
The Agilent Technologies PL1110-1520 GPC/SEC Guard Columns, part number PQR65, are an essential accessory for Gel Permeation Chromatography (GPC) and Size Exclusion Chromatography (SEC) applications. These guard columns are designed to protect your analytical columns from contaminants and ensure the longevity of your columns.
The guard columns are constructed with a high-quality, stable stationary phase that is chemically bonded to a porous silica support. This stationary phase provides excellent column efficiency and long-term stability, ensuring consistent and reliable separations over time. The columns are also equipped with an inlet and outlet filter, which helps to prevent the entry of particles and other contaminants into the analytical columns.
The PL1110-1520 GPC/SEC Guard Columns have a nominal length of 15 cm and an internal diameter of 7.5 mm. They are compatible with Agilent's PL1110 series GPC/SEC systems, making them an ideal choice for laboratories and research facilities that use these systems regularly. With a flow rate range of 0.1-5.0 mL/min, these guard columns can accommodate a wide range of sample volumes and analysis requirements.
The columns are also designed to be easy to use and maintain. They come with a disposable pre-filter assembly, which simplifies the process of changing filters and minimizes downtime. Additionally, the guard columns are compatible with a range of mobile phases, including water, methanol, acetonitrile, and mixtures of these solvents.
In summary, the Agilent Technologies PL1110-1520 GPC/SEC Guard Columns, part number PQR65, are an essential accessory for any GPC or SEC system. Their high-quality construction, long-term stability, and ease of use make them an indispensable tool for laboratories and research facilities that require precise and consistent separations. Whether you are analyzing polymers, proteins, or other macromolecular compounds, these guard columns will help ensure the best possible results from your GPC or SEC system.
Agilent PL1110-1520 GPC/SEC Guard Columns (P/N PQR65) are used in Gel Permeation Chromatography (GPC) and Size Exclusion Chromatography (SEC) applications for protecting the separation columns from contaminants and ensuring the stability of the column packing. Here are some pros and cons of purchasing these guard columns:
Pros:1. High Quality and Reliability: Agilent is a well-known and reputable brand in the field of chromatography. These guard columns are manufactured with high precision and are designed to provide consistent and reliable performance.
