FAQ
1. How long can a C18 column be used normally?
- HPLC column life is generally not calculated by time, but by the number of continuous injection needles, which is more scientific.
In normal use and maintenance, within the range of pH and temperature, the C18 column can reach 500-2000 needle injection life, depending on the cleanliness of the sample.
2. Can the hplc column cap frits be removed and cleaned by ultrasonic waves? What are the adverse consequences?
- It is not recommended to remove the column cap frit for cleaning, because removing the pressurized column frit will
cause changes in the column bed and affect the chromatographic performance. The contaminated HPLC column
should be cleaned and maintained first. If the maintenance has no effect, the HPLC column cap frit should be removed
and washed as a last resort.
3. Does the equilibration time of the column have a lot to do with the packing material? Which is the fastest and which is
the slowest?
- According to the chromatographic rate theory, the smaller the particle size, the higher the column efficiency, and when
the particle size is as small as about 2 microns, the resolution will no longer decrease with the increase of the linear
velocity. Therefore, it has changed for a long time. trade-off between speed and resolution".
