Description
Technical field
The invention belongs to test instrument field, and in particular to a kind of fixed derivatization sample of four-way for derivative reaction
Product bottle stand.
Background technology
Derivatization is to analyze one of the pretreatment technology commonly used in testing field.In application gas chromatography and gas-chromatography
Analytical reagent composition test polarity is big, boiling point is high, during the trace materials of difficult volatilization, it usually needs object is performed the derivatization
Treatment, to reduce its polarity and boiling point, increase volatility, makes it easier to analyzed detection.
Derivative reaction reagent bottle specification predominantly 2.0mL, 4.0mL for being used in present analysis test pre-treatment field and
The screw socket glass sample bottle of 10.0mL.The bottle cap of these screw socket sample bottles is usually polypropylene or polyethylene material, liner poly- four
PVF pad, its distinguishing feature is bottle cap screw thread less (generally only 2-4 circle) and screw thread is shallower, is difficult to when being assembled with bottle
Form larger adhesion and obtain good air-tightness.
It is well known that many derivatization processes are needed with the stronger low boiling point organic solvent of volatility as reaction dissolvent, together
When need in higher temperature (such as：60-120 DEG C) under can just carry out.Using lower boiling reaction dissolvent and reaction temperature higher
Degree can cause gas expansion, the increased pressure in sample bottle during derivatization, cause to occur material in sample bottle and leak, even
The situation that bottle cap ftractures or upsprings, so as to directly result in derivative reaction failure, what is more seriously leaked in sample bottle is poisonous
Harmful substance can cause experimenter's health and Environmental security to endanger.
Currently, the reply sample pressure in the bottle increase and cause material to leak, bottle cap cracking or the effectively sealing such as upspring are asked
Topic aspect, commercially available derivatization sample bottle is not improved from structure, it is difficult to the problem is solved from the angle of sample bottle.
Therefore, a kind of effective method is sample bottle to be reinforced from outside, in the hope of solving the problem.
Occur that material leaks, bottle cap cracking or upsprings etc. effectively close in derivatization process to tackle derivatization sample bottle
Envelope problem, the invention provides a kind of fixed derivatization sample bottle stand of four-way, is applied to prevent material in bottle from leaking, real
Existing derivative reaction is smoothed out and protects the person, the safety of environment.
The content of the invention
It is an object of the invention to provide one kind for effective sealing problem that sample bottle during solution derivatization reaction is present
The fixed derivatization sample bottle stand of four-way.
To achieve these goals, present invention employs following technical scheme：
A kind of fixed derivatization sample bottle stand of four-way, including sample bottle frame body, three parts of pressing plate and fixing nut,
Pressing plate is fixed through fixing nut with sample bottle frame body, it is characterised in that：Described sample bottle frame body is distinguished from bottom up
It is base plate and orifice plate, both are connected by four root posts and form a fixed entirety.
Further, described pressing plate, base plate and orifice plate are identically shaped and sized, and the circular hole on orifice plate has and spreads out
The diameter of biological sample bottle matching.
Further, four described root posts are located at four positions at angle of base plate and orifice plate respectively, four circular hole positions on pressing plate
In four Angle Positions and with the diameter matches of column.
Further, the upper end of four described root posts is the threaded rod matched with fixing nut.
The sample bottle stand application method：In the circular hole on derivatization sample bottle insertion orifice plate after being sealed through threaded cap, will
Pressing plate is nested on sample frame body by column, is tightened through fixing nut, is put into baking oven heating and is performed the derivatization reaction.
The advantage of the invention is that：
1) be fixed on sample bottle in sample bottle stand using rigid pressing plate by the present invention, can give bottle cap from outside corresponding
Pressure, the pressure that gas expansion brings to bottle cap in bottle during derivative reaction is offset, so as to solve letting out for material in bottle
The relevant issues of dew, bottle cap cracking or the derivatization sample bottle sealability such as upspring.
2) present invention can effectively solve effective sealing problem of sample bottle during derivatization, ensure that derivative reaction enters
Row, health and Environmental security.
