PEEK Capillary Tubing
In the realm of chromatography applications, the choice of materials can significantly impact the performance and reliability of the entire system. PEEK (polyetheretherketone) capillary tubing has emerged as a versatile and highly prized material in these fields, thanks to its unique properties that enable precision, flexibility, and compatibility.
Enabling Precision in Chromatography Systems
Chromatography, with its varied techniques like high-performance liquid chromatography (HPLC) and gas chromatography (GC), often demands capillary tubing that can withstand the rigors of chemical analyses. PEEK's exceptional chemical resistance makes it an ideal choice for such applications. It can endure exposure to a wide range of solvents, acids, and bases, ensuring the purity of the samples and the integrity of analytes, which is crucial in achieving reliable results.
PEEK capillary tubing also offers excellent mechanical strength, even at elevated temperatures. This property is especially valuable in techniques like high-performance liquid chromatography (HPLC), where temperature control is critical for efficient separations. The tubing's stability guarantees that flow rates remain consistent, retention times are precise, and chromatographic conditions are maintained with accuracy and repeatability.
The smooth inner surface of PEEK tubing minimizes surface adsorption, a critical factor in achieving sharp and well-resolved peaks. Surface adsorption can lead to analyte loss or peak broadening, impacting the quality of chromatographic results. PEEK's low surface adsorption ensures that the tubing itself does not interfere with the separation process, resulting in cleaner and more reliable data.
