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!

The product has been continuously upgraded and has been recognized by domestic and international markets, and is exported to more than 20 countries such as India, South Korea, Norway, Hungary, Germany, the United Kingdom, and Russia. Hanbon provides users with a dynamic axial compression column with an inner diameter range from 50mm to 2000mm, providing customized services. Laboratory chromatographic column include conventional high-performance liquid chromatography columns, spring columns, dynamic axial compression columns, and multifunctional axial compression columns. How Do I Choose A Suitable Preparative Column? Step 1: Choose the right packing material. The smaller the particle size the higher the column efficiency, but the higher the price and the higher the column pressure, requiring higher pressure tolerance in the equipment hardware. Step 2: Choose the right bonding phase and pore size. How to choose the right carbon content and particle size according to the molecular weight of the substance is a very important issue. Step 3: Selecting the right column tube. The sample is to be served in proportion to the cross-sectional area of the column. The inner diameter of the column is to be selected to suit the sample serving size. Step 4: Determine the appropriate flow rate and loading volume The flow rate of the prepared column: generally proportional to the square of the diameter. Sample loading volume: a combination of purification time, solvent usage, efficiency of the column and sample purity. Technical Advantages Of DAC DAC columns are controlled by dynamic axial compression, which enables dynamic pressure retention and prevents collapse of the column head, loss of column efficiency and poor reproducibility, etc. If a DAC column loses efficiency after prolonged use, the packing can be pushed out after removal of the column, and the column can be homogenized and loaded again. The whole reloading process is not difficult and takes about 1-2H. We provide octadecylsilanized silica gel column, jacketed chromatography column, guard column used in liquid chromatography, chromatography column packed with silica gel, silica gel hplc column, precolumn hplc, different columns used in hplc, etc. For more information, please feel free to contact us!

Bio-Con® auto dilution system is to mix various concentrated buffer solutions, including acid, alkali, salt, etc., with injection water online to prepare the required buffer solution. Different concentrations can be accurately prepared according to specific usage situations. The online dilution and preparation system can quickly achieve stable control parameters. It can also be integrated with the Bio-Pro® pilot & process chromatography system or Bio-TFF tangential flow filtration system as a whole, continuously completing the process of "preparation + chromatography or preparation + tangential flow filtration", overall control and data recording. The overall system is based on DCS+BATCH system control, which can achieve centralized management, centralized control, batch processing, and batch control of the system, with a higher degree of automation. The Difference Between Dilution And In-Line Dilution The Inline Dilution System is similar to the two-pump gradient mode and allows for buffer dilution within a certain range. However, given the solubility of the mother liquor, pH shift after dilution and other phenomena, the robustness of buffer formulation is limited in large-scale applications. The in-line conditioning system uses a single component mother liquor of acid system, base system, salt system, water and additive system to perform buffer formulation, simulating the traditional laboratory formulation mode, with corresponding pH and conductivity feedback adjustment added during the formulation process for improving buffer preparation stability. The in-line buffer configuration is a single-component buffer concentrate with high solubility and can therefore be diluted up to a hundred times, which allows the volume of the buffer tank to be reduced a hundred times and can really solve the efficiency of room utilisation in the dispensing room or between uses. It is possible to obtain an in-line buffer configuration system that has obvious advantages over in-line dilution systems in terms of scalability and adaptability, and at the same time provides a better solution for modern buffer preparation. The Need For In-Line Automatic Buffer Conditioning Systems Buffer preparation for chromatography and filtration steps in bioprocessing is a challenge in terms of providing timely buffer delivery, reproducibility, and good process economics. Traditionally, buffer preparation relies mostly on manual work, which is labour-intensive and makes it difficult to avoid human errors, such as inaccurate weighing or deviations in the dosing of injection water for dilution. In addition, the target buffer must pass various quality control tests before it can be used in production, resulting in long dispensing cycles. The tanks must also be thoroughly cleaned and validated if they are used for other liquids. Another issue that should not be overlooked is that these large dispensing and storage tanks take up a lot of money and plant space. We provide dilution system cleaning, dilution equipment, automated dilution machine, dilution control, dilution dispenser, etc. For more information about preparation of pharmaceutical buffer solution, please feel free to contact us!
