How to choose a right capillary column?
1. Column length
 The resolution is proportional to the square root of the column length. Under other conditions unchanged, 4 times the column length is required to obtain doubled resolution. Shorter columns are suitable for simpler samples, especially those composed of components that differ greatly in structure, polarity, and volatility.
15m short column is used to quickly separate simpler samples and is also suitable for scanning analysis;
30m chromatographic column is the commonly used column length, most of the analysis is done on this length of the column;
50m/60m or longer chromatographic columns are used to separate more complex samples.
2. Column inner diameter
The inner diameter of the column directly affects the efficiency, retention characteristics and sample capacity of the column. Small-bore columns have higher efficiency than large-bore columns, but the column capacity is smaller
0.25mm: Has higher column efficiency and lower colum
