| Faster separation speed achieves high throughput and high yield
Utilize CORTECS chromatography column to increase flux. The CORTECS 2.7 µ m chromatographic column has operational advantages under lower back pressure conditions and does not affect analytical efficiency or separation. It can achieve faster high-performance separation. After equipping the CORTECS 1.6 µ m chromatography column with an ultra-low diffusion system (such as the ACQUITY UPLC I-Class system), high performance can be achieved.

Extend column lifespan with VanGuard protection column
In drug, natural product, environmental, and chemical analysis, complex sample matrices are often encountered, which greatly shorten the lifespan of the analytical chromatography column and deteriorate the spectral performance. The Waters VanGuard integrated pre column and VanGuard split protection column help improve the lifespan of analytical chromatography columns by intercepting particulate matter and adsorbed chemical pollutants in the mobile phase and sample solution, without reducing chromatographic separation efficiency.
