| ZIC-cHILIC 150Å | 4.6 | 150 | 7.8 |
| ZIC-cHILIC 250Å | 4.6 | 250 | 7.8 |
The unique design of SeQuant™ ZIC®-cHILIC 100Å Columns ensures that the stationary phase is highly stable and resistant to degradation, providing long-lasting performance and reproducibility.
Enhanced Selectivity
One of the key advantages of SeQuant™ ZIC®-cHILIC 100Å Columns is their enhanced selectivity. The cation-exchange stationary phase allows for the separation of analytes based on their charge, while the hydrophilic interaction allows for the separation of polar compounds. This dual selectivity provides a versatile tool for separating a wide range of analytes with high efficiency. The table below demonstrates the improved selectivity of SeQuant™ ZIC®-cHILIC 100Å Columns compared to a traditional C18 column.
| Analyte | Traditional C18 Column (Resolution) | SeQuant™ ZIC®-cHILIC 100Å Column (Resolution) |
|———|————————————-|———————————————-|
| Compound A | 1.5 | 2.5 |
| Compound B | 2.0 | 3.0 |
| Compound C | 1.8 | 2.8 |
The improved selectivity of SeQuant™ ZIC®-cHILIC 100Å Columns allows for more accurate and precise analysis of complex mixtures.
Increased Efficiency
The high efficiency of SeQuant™ ZIC®-cHILIC 100Å Columns is attributed to their small particle size and optimized pore structure. The small particle size reduces the diffusion path of analytes, resulting in shorter analysis times and improved resolution. The optimized pore structure ensures that the analytes are effectively retained and separated, leading to higher peak capacity and better reproducibility. The table below compares the efficiency of SeQuant™ ZIC®-cHILIC 100Å Columns with a traditional C18 column.
| Column Type | Resolution Factor (N) | Retention Time (min) |
|————-|———————–|———————|
| Traditional C18 Column | 1.5 | 10 |
| SeQuant™ ZIC®-cHILIC 100Å Column | 2.5 | 5 |
The increased efficiency of SeQuant™ ZIC®-cHILIC 100Å Columns allows for faster analysis and higher throughput in the laboratory.
