Description
Technical field
The utility model relates to a kind of electron paramagnetic resonance (EPR) or electron spin resonance (ESR) measuring technology, especially in order to improve EPR/ESR test special-purpose dress sample and a cleaning tool, specifically a kind of EPR test tool set of EPR/ESR wave spectrum detection efficiency and quality.
Background technology
Electron spin resonance (electron spin resonance, ESR) is named again in electron paramagnetic resonance (electron paramagnetic resonance, EPR), in 1945, is detected first by Zavoisky in solid.Due to its high sensitivity and to tested article without destroying and getting involved, make it become one of desirable analysis means.Its detected object is divided into two large classes: 1. in molecular orbit, occur the unpaired electronics material of (or claiming single electron).2. in atomic orbital, there is the material of single electron.In fact, EPR detects the many fields such as physics, chemistry, material, biology and medical science that have been widely applied to now.Epr signal detects and adopts EPR spectrometer to realize.If sample is solid, generally need first be pulverized, weigh, carefully pack external diameter f4-5mm, internal diameter f2.5-4mm, length into and be 100-250mm, tubing and be in quartzy ESR testing tube, then be placed in the resonator cavity of EPR spectrometer and carry out Multiple-Scan mensuration.
Density is little, viscosity is large for powdered sample, especially biomass samples (paper wood, timber, plant shell son, animal skin etc.), and EPR testing tube internal diameter is narrow, pipeline is long, and dress sample and drawing is got all very difficult, is infected with tube wall serious during cleaning.The spoon that Experiment of General Chemistry chamber is used, shovel, spoon instrument are too large, have been difficult to this work.For this reason, need to design a kind of specific purpose tool to facilitate dress sample and the cleaning task in EPR test, necessary.
Summary of the invention
The purpose of this utility model is for the dress sample in EPR test and cleans inconvenient problem, designs a kind of EPR test tool set, to have facilitated sample to pack into, draw and get and tube wall cleaning.
The technical solution of the utility model is:
A kind of EPR test tool set, the fork 2 that it comprises EPR testing tube 1 and can free in and out EPR testing tube 1, pull out son 3, sleaker 4 and brush 5, the head of described fork 2 is V font or serrate, the overall width L of end and the internal diameter of EPR testing tube match, the described end of pulling out son 3 is tip, the all or part of hangnail that is provided with in bar portion both sides more than end, the overall width L of end and the internal diameter of EPR testing tube match, the end of described sleaker 4 is semicircle, its radius and EPR testing tube match, the end of described brush 5 is provided with semicircle head, the all or part of sawtooth that is wound around absorbent cotton that is provided with in bar portion both sides that semi-circular head is above, the overall width L of end and serrated portion is less than the internal diameter of EPR testing tube.
Described fork 2, the bar length of pulling out son 3, sleaker 4 and brush 5 are all 100-300mm, and bar footpath is f2mm, and bar is being ellipse.
Described fork 2, pull out son 3, sleaker 4 and brush 5 are stainless steel products.
Wherein:
1, fork: head is V font or serrate, A/F <2.5-4mm.
2, pull out son: tip, both sides hangnail type, A/F <2.5-4mm.
3, sleaker: head is semicircle, and radius (r) is equal to EPR testing tube r=2.5-4mm.
4, brush: semicircle head, both sides sawtooth pattern, be wound around absorbent cotton, A/F <2.5-4.0mm.
5, the bar length of above-mentioned four instruments is all 100-300mm, f2mm, and bar is being ellipse.Material is stainless steel.
the beneficial effects of the utility model are:
Biomass samples density is little, viscosity is large, and powdered sample disperses face large, wiping difficulty.The spoon that Experiment of General Chemistry chamber is used, shovel, spoon instrument are too large, cannot go deep in long and narrow EPR testing tube, complete dress sample, draw and get and cleaning.
1, fork both can be pitched the soft samples such as paper wood, cortex, made sample integral-rotation advance and retreat, hard, soft sample directly can be pushed into again to the pipe end, compacting.
2, pulling out sub-usage is first will pull out sub-nose cone to enter in paper wood, cortex sample, and then sample integral body is drawn, brought out.
3, sleaker can be pushed into powdered sample the pipe end, also can when cleaning, tube wall powder be scraped totally.
4, brush is mainly used in purge pipe inwall.During use, first rotate and will in EPR pipe, mince and take out of, then be wound around brush head with absorbent cotton, rotary-cleaning tube wall repeatedly, after take absorbent cotton away.
5, adopt this cover instrument to fill sample and cleaning, speed is fast, and loss is few, can improve EPR/ESR wave spectrum testing efficiency more than 1 times.
6, owing to adopting specific purpose tool dress sample, powder, lightweight and the fully compacting of maceration sample, tested region height is consistent, and measurement accuracy can improve more than 10%.
Accompanying drawing explanation
Fig. 1 is complete specific purpose tool schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
