动态轴向压缩柱DACDynamic axial compression column DAC
1.装柱时间短，无需二次拆装，可避免传统色谱柱在拆装时柱床反弹影响柱效
2.本公司自主研发设计的流体分配方式保证了分配的均匀性，高效性。
3.活塞头与柱床始终接触并保持装柱压力，避免了传统色谱柱长时间使用后柱床塌陷的问题，延长使用寿命
4.不使用电气零部件，可用于防爆区域(或者可采用使用防爆电机的液压站
1. The column loading time is short, and there is no need for secondary disassembly and assembly, which can avoid the rebound of the column bed during the disassembly and assembly of the traditional chromatographic column, which can affect the column efficiency
2. The fluid distribution method independently developed and designed by the company ensures the uniformity and efficiency of distribution.
3. The piston head is always in contact with the column bed and maintains the column loading pressure, which avoids the problem of column bed collapse after long-term use of the traditional chromatography column and prolongs the service life
4. No electrical parts are used, and can be used in explosion-proof areas (or hydraulic stations using explosion-proof motors can be used.)

我公司生产的弹簧预紧色谱柱（SAC）相比其它厂家产品的优势在于：
1）采用气缸替代气动液压放大泵。其优势所有管路均为气压管路，除了色谱柱管内部压力，其它压力均不超过8bar，安全性更好；其次，只使用压缩空气作为动力来源，操作环境更清洁。
2）管路布局更为简洁。省去了气压转液压的所有零部件，一致性更好，操作空间更大更方便。
3）特殊设计的柱底密封结构，只用手拧紧即可实现密封。
4）特殊设计加工的分配方式，可以保证色谱柱的高柱效。
5）操作时间短，节省试剂。
1. With a set of column machines, multiple columns can be filled
2. The column loading time is short, and there is no need for secondary disassembly and assembly, which avoids the rebound of the column bed during the disassembly and assembly of the traditional chromatographic column and affects the column efficiency
3. The piston head is always in contact with the column bed and maintains the column loading pressure, which avoids the problem of column bed collapse after long-term use of the traditional chromatography column and prolongs the service life.
4. Specially designed column bottom sealing structure to ensure good sealing
5. Specially designed and processed forced distribution and collection system can ensure the high performance of the column
6. Inner wall surface roughness Ra ≤0.2μm
7. The inner wall adopts honing, polishing and processing technology
The advantages of our spring preloaded column (SAC) compared with other manufacturers' products are:
1) Adopt pneumatic cylinder instead of pneumatic hydraulic amplification pump. Its advantages are that all the pipelines are pneumatic lines, except for the internal pressure of the chromatography column tube, the other pressures are not more than 8 bar, which is safer, and secondly, only compressed air is used as a power source, and the operating environment is cleaner.
2) The pipeline layout is more concise. All parts of pneumatic to hydraulic pressure are omitted, and the consistency is better, and the operation space is larger and more convenient.
3) Specially designed column bottom sealing structure, sealing can be achieved by only hand tightening.
4) The distribution method of specially designed processing can ensure the high column efficiency of the column.
5) Short operation time and saving reagents.

Spring-loaded columns (SACs) are autopacked columns developed for high-pressure preparative chromatography. The advantages are:
1) The column loading time is short, and there is no need for secondary disassembly, so it can avoid the rebound of the column bed during the disassembly and assembly of the traditional chromatographic column, which can affect the column efficiency.
2) The piston head is always in contact with the column bed and maintains the column loading pressure, which avoids the problem of column bed collapse after long-term use of the traditional chromatographic column and prolongs the service life.
