The invention can be matched with existent fiber-optical spectrograph, and can be extensively used in several fields of bio-chemistry, clinical medicine and others.
Description
Technical field
The invention belongs to technical field of analytical instruments, particularly relate to a kind of full-automatic miniature biochemical analysis sample chamber.
Background technology
In the prior art, the used sample chamber of micro fiber spectrometer does not have constant temperature system, and conventional sample chamber does not have the function of dynamic replacing sample yet.Can not solve the biochemistry detection that some need constant temperature, and owing to can't dynamically change sample, thereby can't carry out real-time detection the detected object that material composition and content of material change at any time.
Summary of the invention
The full-automatic miniature biochemical analysis sample chamber that a kind of constant temperature, amount of samples are few, cost is low that provides is provided at the deficiencies in the prior art.
The present invention comes to be realized by the following technical programs: full-automatic miniature biochemical analysis sample chamber, and it is made of illuminator, sample control system, optically coupled system, and integral body places in the shell.Wherein the sample control system comprises sample cell, Micropump, and Micropump connects sample cell by the turnover pipeline, and sample is implemented dynamic sample introduction.
The present invention also is provided with temperature control system, is made up of conductor temperature regulator and temperature control circuit, is positioned near the sample cell, realizes the constant temperature of sample cell.
Optically coupled system of the present invention comprise be positioned on the light path and be positioned at sample cell after lenticule and by its optical fiber that picks out, the output light of optical fiber can detect for the absorption spectrum that fiber spectrometer carry out material.
Illuminator of the present invention comprises concave mirror, light source and lenticule, and light source is between concave mirror and lenticule.Further improve under the situation of pale pinkish purple efficient at need, collimation lens, convergent lens can also also be set behind light source, again lenticule be set and connect another lenticule by optical fiber.Owing in native system, adopted micro-optical component, therefore the volume of total system reduced greatly.Make also corresponding the reducing of the amount of getting of required detection material simultaneously.
Adopt the technical program, can realize of the full-automatic dynamically replacing of biochemical spectral analysis sample chamber to sample, it has characteristics such as volume is little, constant temperature, amount of samples is few, cost is low, can be supporting with existing fiber spectrometer, be widely used in various fields such as biological chemistry, clinical medicine, legal medical expert's criminal investigation, environmental science, modern field operations and national defence.
