Description
Technical field
The utility model relates to a kind of chromatographic column device.
Background technology
Chromatographic column is the main body in gel chromatography technology, generally with glass tube or lucite tube.The diameter of chromatographic column does not affect separating degree, and amount of samples is large, can add the diameter of huge pillar, general preparation gel column, and diameter is greater than 2 centimetres, but sample should be uniformly distributed on gel column bed surface when application of sample.In addition, enlarged diameter, eluting liquid volume increases, and Sample Dilution degree is large.Separating degree depends on that post is high, is separated different component, and gel column bed must have suitable height, and the square root that separating degree is high to post is relevant, but because the too high crimp of soft gel column is blocked, is generally no more than 1 meter.Short column while dividing family separated, general gel column length 20-30 centimetre, comparison 5:1-the 10:1 of post height and diameter, gel bed volume is 4-10 times of sample solution volume.When classification is separated, post line high and diameter is 20:1-100:1, and conventional gel column has 50 * 25 centimetres, 10 * 25 centimetres.
In chromatographic column, generally all can use dress column valve, traditional dress post unloads post technique and is: traditional dress post can adopt by hand filler solution is directly poured in post bucket, or utilizes intelligent biological pump to be pumped in post bucket, at this time piston must be disassembled.When unloading post, due to chromatography work complete after filler in drier state, just intelligence adopts manual excavation and filling material to go out post bucket, need to dismantle equally piston and hoisting mechanism, also can utilize pump oppositely to pressure water injection in post bucket, constantly dilution filler is poured out filler or utilize intelligent pump sucking-off by hand again after diluting completely, and whole process must disassemble piston and hoisting mechanism could realize.
Traditional chromatographic column assembly process process: chromatographic column handling column operation is convenient not: because this chromatographic column is to work under low-pressure state, be not equipped with automatic mounting column valve simultaneously yet, so when dress post unloads post, hoisting mechanism and piston must be removed, after filler dilute with water, pour out by hand, filler solution is poured in post chamber, that is to say, complete dress post and unload post This move and at least need to pull down hoisting mechanism and piston 2 times, operate convenient not.
