Along with the development of the biopharmaceutical industry, more and more companies are entering into clinical trials and commercial production, and a stable, reproducible and easy-to-use loading process is becoming a demand of more and more companies. Manual column loading faces many problems such as poor reproducibility, time-consuming method development, and complicated maintenance processes.
ACC automatic chromatography column was born, which controls the forward or reverse motion of the motor through position feedback or pressure feedback to realize the automatic lifting and lowering of the column head; through the valve opening and closing and pneumatic diaphragm pump to realize the filling and recovery of the gel. After years of precipitation, it has now developed into the latest generation of mature fully automatic intelligent chromatography columns.
The theoretical plate number and symmetry factor of a chromatographic column are important indicators of column efficiency. Factors that affect the theoretical column plate number and symmetry factor of chromatography columns include:
column size and packing type
The nature of the mobile phase
the nature of the sample
Temperature and pH
In addition, the structural design of the chromatographic column itself also affects the column efficiency of the chromatographic column. Such as the material and surface roughness of the column wall, the tightness of the packing, the uniformity of the mobile phase distribution, etc. Excellent column performance is dependent on the structural design of the column.
