Hanbon advanced chromatography systems has reliable performance and flexible configuration, and can provide Bio-Lab® laboratory chromatography system, Bio- Pro® pilot&process chromatography system, etc. ommon Principles Of Process Scale-Up: Linear Scale-Up Linear scale-up is the most common principle used in process scale-up. By linear scale-up, we mean that we can obtain almost uniform bioprocess chromatography results from laboratory scale to pilot results or industrial production level. The core idea is to keep the column height and linear flow rate constant and only scale up the column diameter and volume flow rate. A fixed column height and linear flow rate theoretically ensures the same retention time, the number of CVs used in chromatography and the number of CVs of the eluted sample, maximizing the same purification results. Theoretically, this linear scale-up of the purification separation behavior should be very similar, thus ensuring a successful scale-up of the ion chromatography process. However, some additional factors need to be considered, including a decrease in column tube support (increased pressure drop), column efficiency/column bed instability, sample diffusion (peak spreading), and dead volume of the system and tubing. Conversion Of Linear Flow Rates (Cm/H) To Volumetric (Ml/Min) Flow Rates When comparing results from columns of different sizes, it is convenient to express the flow rate as a linear flow rate (cm/h). However, flow rates are often measured as volumetric flow rates (ml/min). In order to convert between linear and volumetric flow rates, one of the following equations can be used . Linear flow rate (cm/h) to volumetric (ml/min) flow rate Volumetric flow rate (ml/min) = linear flow rate (cm/h) / 60 x column cross- sectional area (cm2) =Y/60×π×d2/4 Y = linear flow rate (cm/h) d = internal diameter of the column (cm) e.g.: There is a glass column (inner diameter 1.6 cm), when the linear flow rate is 150 cm/h, what is the volumetric flow rate? Y=Linear flow rate = 150cm/h d = inner diameter of the column = 1.6 cm Volumetric flow rate = 150 x π x 1.6 x 1.6/(60 x 4) From volumetric flow rate (ml/min) to linear flow rate (cm/h) Linear flow rate (cm/h) = volumetric flow rate (ml/min) x 60/column cross- sectional area (cm2) =Z×60×4/π×d2 Z = volumetric flow rate of the column (ml/min) d = inner diameter of the column (cm) e.g.: There is a glass column (inner diameter 0.5 cm), when the volumetric flow rate is 1 ml/min, what is the linear flow rate? Z = volumetric flow rate of the column = 1 ml/min d = inner diameter of the column = 0.5 cm Linear flow rate = 1 x 60 x 4/(π x 0.5 x 0.5) cm/h = 305.6 cm/h We provide chromatography step by step method, chromatography purification method, chromatography process example, anion exchange chromatography elution, equipment used for chromatography, etc. For more information, please feel free to contact us!

Hanbon process chromatography columns can meet the use requirements of most chromatographic fillers. Its good filling effect and high column efficiency meet the needs of customers from pilot to large-scale production. Laboratory LCC®chromatographic columns, MCC® manual adsorption chromatography column, and ACC® automatic axial compression chromatography columns are available. Chromatography Columns in Commercialization Phase Selection 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. Factors Affecting Column Efficiency 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. We provide chromatography column qualification, small chromatography column, protein a chromatography column, mixed mode chromatography columns, low pressure chromatography columns, cation exchange column elution, etc. For more information, please feel free to contact us!
