The RESTEK 13620-127 Rxi-5Sil MS 10m x 0.25 mm ID x 150 m Film column is a high-performance gas chromatography (GC) column designed for the separation and analysis of volatile and semi-volatile compounds. This column features a 10-meter length and a 0.25 mm internal diameter, with a 150 m thick film thickness.
The column is coated with RESTEK's proprietary Rxi-5Sil MS stationary phase, which is a highly polar and stable phase that provides excellent separation efficiency and reproducibility. The Rxi-5Sil MS phase is composed of 5% diphenyl, 95% dimethylpolysiloxane, with trifluoropropyl methyl siloxane as a polar modifier. This phase is highly suitable for the separation of a wide range of analytes, including organic acids, alcohols, aldehydes, ketones, and aromatic compounds.
The column is designed for use with mass spectrometry (MS) detectors, such as quadrupole, time-of-flight (TOF), and quadrupole-TOF (QqTOF) systems. The thin film design of the column provides excellent sensitivity and mass resolution, making it an excellent choice for trace-level analysis and high-throughput screening applications.
The column is also equipped with a 15-meter long, 0.25 mm ID guard column, which is designed to protect the analytical column from contamination and ensure consistent performance over time. The guard column is coated with the same Rxi-5Sil MS stationary phase as the analytical column, ensuring that the separation efficiency and retention times of the analytical column remain constant.
In summary, the RESTEK 13620-127 Rxi-5Sil MS 10m x 0.25 mm ID x 150 m Film column is a high-performance GC column that is ideal for the separation and analysis of volatile and semi-volatile compounds using MS detectors. With its thin film design, excellent separation efficiency, and high sensitivity, this column is an excellent choice for trace-level analysis and high-throughput screening applications.
Pros of buying a 13620-127 Rxi-5sil MS 10m x 25um Restek column with 10m guard:1. High efficiency and separation power due to its narrow bore and short length.
2. Suitable for analyzing volatile and semi-volatile compounds due to its Rxi-5sil stationary phase.
3. Excellent column stability and reproducibility due to its MS grade material.
4. Compatible with various GC systems due to its universal dimensions and connections.
Cons of buying a 13620-127 Rxi-5sil MS 10m x 25um Restek column with 10m guard:1. Higher cost compared to standard columns due to its high-performance materials and construction.
2. May require specialized knowledge and equipment for optimal use and interpretation of results.
3. Limited capacity for large sample volumes due to its small inner diameter.
In conclusion, the 13620-127 Rxi-5sil MS 10m x 25um Restek column with 10m guard is a high-performance GC column suitable for analyzing volatile and semi-volatile compounds with excellent efficiency and separation power. Its high cost and limited sample capacity should be considered, but for applications requiring high-resolution chromatography, it is a worthwhile investment.
Recommendation: If you have the budget and technical expertise to utilize a high-performance GC column, the 13620-127 Rxi-5sil MS 10m x 25um Restek column with 10m guard is an excellent choice. It will provide you with reliable and accurate results, making it a valuable addition to any GC system.
