Description
Technical field
The invention belongs to field of biotechnology more particularly to existing isotope mass spectrometer to be applied to siphonopods, fish isogonism
When the carbon of the soft tissues such as the sclerous tissues such as matter jaw, inner casing and muscle, sexual gland, nitrogen stable isotope determination trace samplings sampling and
Embed utensil.
Background technique
When carrying out the bioecologys such as siphonopods, fish, breeding ecology research, the survey of the stable isotopes such as carbon, nitrogen
Setting analysis is an important research contents.It was distributed in marine food web nutrition relationship, the breeding Energy input of these types
Cheng Zhong, ingest source, surplus Energy input method of salary distribution etc. of ingesting of food organisms decide growth, development, and final numerous
Spread out activity and tactful selection adaptation of laying eggs.With the development of current engineering technology, Measurement for Biochemistry, stable isotope skill
Art has become one kind maturely and is widely used in the research of marine organisms Feeding Ecology, marine organisms breeding ecology,
It can be with the consumer organism source of tracer marine organisms, the accumulation of individual surplus energy of ingesting and its distribution etc..The stabilization used is same
The plain instrument in position has the advantages that simple, easy, safely and fast isotopic masses such as measurement carbon, nitrogen.
In general, needing to carry out 1.0mg~1.5mg to dry tissue samples before carrying out tissue stabilization isotope assay
The extraction and encapsulation embedding of trace pulverized specimen.However, it is limited to the tool limitation that current trace samplings extract and encapsulation embeds, it is difficult
Tissue pulverized specimen is extracted with disposably trace, and extracts with needing multiplicating property-weighs, increase extraction-weighing, even
It is that trace subtracts and takes-weigh.In this way, the muptiple-use step that repeats is easy to cause the trace samplings that finally weigh there are deviation, to survey
Determine result and subsequent analysis and research generate very big otherness；Meanwhile this repetition extraction-weighing step, definitely increasing
Add sample is contaminated to happen, has increased the uncertainty and its error of measurement result.It is mentioned in addition, trace is repeated several times
After taking-weighing, existing experimental tool can not easily encapsulate embedded samples, increase experimental cost and its time at
This.
Therefore, in the stable isotope determination analysis of tissue samples, as far as possible easy, quick, accurately trace is needed
Tissue pulverized specimen is extracted, and is quickly and conveniently packaged embedding to it, to minimize the weighing error of trace samplings, drop
Low experimental cost and its time cost, and reduced to the maximum extent by repeating to measure the issuable dirt of institute in extraction process
Dye happens.
