Hello, this is Chromasir, a brand of Maxi Scientific Instruments. We are a manufacturer of liquid chromatography stainless steel capillary products, which are used for high-performance liquid chromatography (HPLC) applications. In this article, we will introduce the working principle, types, and advantages of our products, and how they can help you achieve better results in your LC analysis.
Liquid chromatography stainless steel capillary products are thin tubes made of stainless steel, which are used to connect different components of an LC system, such as pumps, injectors, columns, detectors, etc. The capillaries have a small inner diameter, usually ranging from 0.1 mm to 1 mm, and a length of several centimeters to several meters, depending on the system configuration. The capillaries are designed to withstand high pressure and temperature, and to minimize dead volume and band broadening, which are critical factors for LC performance
There are different types of liquid chromatography stainless steel capillary products, depending on the material, size, and shape of the capillaries. Some common types are:
• Flexible stainless steel capillaries: These capillaries have a high flexibility and durability, and can be easily bent and shaped to fit different system layouts. They have a good resistance to corrosion and abrasion, and are suitable for most standard LC applications
• Inert stainless steel capillaries: These capillaries are coated with inert materials, such as PEEK or titanium, to reduce the interaction between the capillary and the sample or solvent. They are ideal for bio-inert LC applications, such as peptide or protein analysis, where sample integrity and recovery are important
• Restriction stainless steel capillaries: These capillaries have a very small inner diameter, usually less than 0.1 mm, and are used to create a pressure drop or a flow restriction in the LC system. They are useful for gradient formation, back pressure regulation, split flow control, etc
The advantages of using liquid chromatography stainless steel capillary products are:
• They can improve the LC efficiency and resolution, by reducing the extra-column volume and dispersion, and maintaining the optimal flow rate and pressure
• They can enhance the LC reproducibility and reliability, by ensuring a leak-free and stable connection between the LC components, and preventing contamination and degradation of the sample or solvent
• They can increase the LC versatility and compatibility, by allowing a wide range of LC configurations and applications, and supporting different LC modes and methods
At Chromasir, we offer a variety of liquid chromatography stainless steel capillary products, with different specifications and dimensions, to meet your LC needs. All our products are engineered and manufactured with high quality and precision, and are compatible with most LC instruments and columns. We also provide customized capillary solutions, according to your specific requirements.
