A guard column shields the HPLC column from impurities, enhancing accuracy and lifespan. It’s crucial for consistent system performance, made of the same material as the analytical column, and periodically renewed.
Guard column in HPLC protects the analytical column, reducing contamination, and improving precision.
Guard columns protect the analytical column, extending its lifespan.
Guard columns enhance analyte resolution by purifying the sample matrix, leading to improved peak shapes and chromatography.
We can customize the design and specification of guard columns based on the specific requirements of the OEM.
We offer private labeling solutions for OEM guard columns, which includes the OEM's branding, logo, and labeling.

2. Achieve Better Chromatographic Separation, accuracy, and reproducibility in your analyses with uHPLCs guard columns.
A guard column is a small column installed between the sample injection port and the analytical column in chromatography. The guard column serves as a sacrificial column, meaning that it is intended to protect the analytical column from contamination and sample matrix effects.
The guard column is typically filled with the same stationary phase as the analytical column, which will help to retain any unwanted contaminants or matrix components that may interfere with the separation of the target analytes. Guard columns are available in a variety of sizes and materials, and they can be easily replaced or cleaned when they become saturated or fouled.
The use of a guard column is essential for maintaining the performance and longevity of the analytical column in chromatography. Without a guard column, contaminants in the sample matrix can accumulate on the analytical column over time, leading to increased baseline noise, reduced column efficiency, and ultimately, the need for more frequent column replacement. So you can know, By using a guard column, the analytical column is protected from these contaminants, and the cost and time associated with column replacement can be minimized.
After using the hplc guard column, especially when the sample is not very clean and there is a need to reconnect it after disassembly,
please pay attention to the connection direction when it is used. Otherwise, it is easy to cause the contamination of the column head
of the guard column to enter the column with the mobile phase, it will lead to contamination of the column head, and the guard column
will naturally fail to perform its protective function. The same applies to the use of copper HPLC columns.
The connection of the guard column is also very important. The shorter the connection line between the chromatographic column and
the guard column, the better, and the inner diameter of the connection tube should be as small as possible.
The guard columns should be replaced when one of the following conditions is met
a. The theoretical column number of the chromatographic column has decreased by more than 15%.
b. The pre-column pressure of the chromatographic column increases by more than 15%.
c. The resolution of the most difficult to separate substances decreases by more than 15%.
d. The number of sample injections exceeds 150.
e. The mobile phase passes through 1500 times the volume of the column.
