There is a lot of weak point in chromatograph of liquid at present, such as what current chromatograph of liquid used during Analysis and Identification, some problems often occur, in traditional chromatograph of liquid flowing mutually, the ratio of organic solvent needs strict control, not so will result in chromatographic system at traditional chromatograph of liquid unstable, cause analysis result inaccurate, and traditional chromatograph of liquid operation complexity, clean inconvenience, there is no gradient elution function, maintenance difficult, therefore, propose a kind of chromatograph of liquid for the problems referred to above and improve device.
Utility model content
Having problems for above-mentioned prior art, this utility model provides a kind of chromatograph of liquid to improve device, owing to the frequency of reciprocating motion of the pistons is higher, analysis result is more accurate, after improving, chromatograph of liquid has gradient elution function, easy to clean, thus solves the problem in background technology.
For achieving the above object, the technical solution adopted in the utility model is: a kind of chromatograph of liquid improves device, including liquid containing bottle, described liquid containing bottle is connected with the check valve being arranged on described liquid containing bottle top by injection port, and arranges eccentric inside described check valve；Described eccentric top connects micromachine and piston set between described eccentric and described check valve；Described check valve top connection pulse buffer, and described pulse buffer side connection injector；Pressure gauge, and described injector one end connection detached dowel are installed between described injector and described pulse buffer；Described detached dowel bottom connects detector, and described detector bottom connection waste liquid bottle；Described detector side is connected with the monitor being arranged on described waste liquid bottle side.
Further, also including outlet and hollow-fibre membrane, described outlet is between pulse buffer and injector；Described hollow-fibre membrane is sleeved on inside detached dowel.
Further, described hollow-fibre membrane is a kind of cancellated hollow-fibre membrane, and hollow-fibre membrane converts into the diameter diameter less than detached dowel.
Further, described check valve is symmetrical arranged.
Further, described piston moves back and forth between check valve and eccentric.
The beneficial effects of the utility model are:
1, compact conformation, service life is long；
2, higher due to the frequency of reciprocating motion of the pistons, analysis result is more accurate, and after improving, chromatograph of liquid has gradient elution function, and chromatographic system is stable, simple to operate；
3, high-resolution, high sensitivity, speed is fast, chromatographic column can be recycled, and it is easy to flow out component easily collecting, easy to maintenance, after use, cleans convenient, has good economic benefit and social benefit, is suitable for promoting the use of.
