Column compatibility is an important consideration when purchasing. Please provide us with your instrument model and system configuration, and we can help you to confirm whether the column is compatible with your system. In addition, you may also consider using a universal connector, which can adapt to many different types of column heads, ensuring a leak-free connection and small dead volume.
2, How long will the column last?
The service life of a column is affected by a number of factors, including sample complexity, mobile phase composition, pressure and temperature conditions, etc. Proper use and maintenance can extend the life of a column. Proper use and maintenance can extend the life of the column. Often, an accelerated rate of pressure rise on a column is a signal to replace it.
3, What is the separation effect of the chromatographic column?
The separation effect depends on the type of column, packing, particle size and chromatographic conditions. Choosing the right column is critical to obtaining a good separation. It is recommended to provide detailed information about the target analyte so that we can recommend the most suitable column.
4, Is the price of the column reasonable?
The price of chromatographic columns varies depending on the brand, material and technology. We offer a wide range of chromatographic columns at various price points to meet the needs of different users. When purchasing, you should not only consider the price, but also the performance and service life.
5. Is there any technical support and warranty service after purchase?
We provide comprehensive after-sales service, including technical support and warranty service. Our technical support team is always on standby to help you if you encounter any problems during use.
