Description of drawings
The micro-photometric structural representation that Fig. 1 provides for the embodiment of the invention.
Fig. 2 is the structural representation in micro-luminosity pond in the micro-photometer structure shown in Figure 1.
Fig. 3 is the cut-open view in micro-luminosity shown in Figure 2 pond.
Embodiment
Referring to Fig. 1, a kind of micro-photometer that the embodiment of the invention provides comprises micro-luminosity pond 1, front supporting member 2, back support member 3, plastic film tape 4, preceding rolling wheel 5, back winding wheel 6 and point sample mechanism 7.Plastic film tape 4 before being wrapped on the rolling wheel 5 is connected with back winding wheel 6 through front supporting member 2, point sample mechanism 7, micro-luminosity pond 1, back support member 3 successively.Plastic film tape 4 should be optical clear, and has the flexible distortion of certain elasticity, and the plastic film tape that some kind plastics is processed through extrusion modling can satisfy this requirement.Front supporting member 2 is roller or pole with back support member 3.Point sample mechanism 7 can be manual liquid-transfering gun, the hyperchannel liquid-transfering gun, and the pipettors on the mechanical arm etc. are used for splashing into drop to plastic film tape.For example, point sample mechanism 7 can be 4 passage liquid-transfering guns or 12 passage liquid-transfering guns.On the rolling wheel 5, through front supporting member 2, micro-luminosity pond 1 and back support member 3, finally be fixed on back winding wheel 6 places again before the present invention is wound in plastic film tape 4 rolling, back winding wheel 6 drives film by the motor-driven rotation and moves, and is similar to the motion of tape.
Referring to shown in Figure 2, micro-luminosity pond 1 comprises body 11, limited block 13 and optical fiber 15.Have slit 14 on the body 11.Body 11 is connected with optical fiber 15.Body 11 is provided with limited block 13.Slit 14 two ends are to have the cambered surface that broadens gradually, when plastic film tape 4 gets into micro-luminosity pond, receive the cambered surface effect, will be folded in half.Owing to have certain tensile force on the film; This tensile force at the slit place along the AB direction laterally; Receive this masterpiece plastic film tape 4 of exerting oneself and will be close on slit 14 walls, slit 14 width are greater than the plastic foil thickness of twice, so a slit also will be left in plastic foil inside.Film kept the center line symmetry when limited block 13 was used to keep doubling, avoided the low folding or rotation of the high side of a side.
Referring to shown in Figure 3, optical fiber 15 comprises outgoing optical fiber 151 and incident optical 152.Outgoing optical fiber 151 and incident optical were located at slit 14 two ends in 152 minutes.Outgoing optical fiber 151 is used to introduce light source.Incident optical 152 is used for accepting to detect light.When drop 8 passes through slit 14, formed oblate column.Source light passes film and drop 8 from the irradiation of outgoing optical fiber 151 end faces, gets into incident optical 152, causes detecting device.Composition to be measured has absorbed the part transmitted ray in the drop, according to langbobier law:
Describe in detail in the face of micro-photometric principle of work down:
Trace photometer when work, Fig. 1 point sample mechanism 7 at first with zero point several sample drops to several microlitres in film central authorities.This moment, drop was with spherical in shape owing to the hydrophobic effect on plastic foil surface.Back winding wheel 6 rotates, and drives plastic film tape 4 and travels forward, and to the cambered surface place of slit, by doubling gradually, the distortion that is squeezed of the drop at this place can form oblate column to slit 14 stenosis, and the fibre-optical probe that passes through is as shown in Figure 3.Droplet size should pass through calculating, makes body diameter after the compression greater than optical fiber outgoing end face height, again less than the plastic tape height, can transmission fluid to guarantee whole light, and drop can not overflow plastic tape and pollute micro-luminosity pond simultaneously.Source light through optical fiber coupling transmission fluid, gets into detecting device at slit 14 places at last.After measure accomplishing, travelling belt continues motion, sees liquid the stenosis of slit 14 off, and plastic tape launches with cambered surface, and liquid is come the rear roller place because hydrophobic effect becomes drop once more.Can use this moment liquid-transfering gun to reclaim, perhaps directly abandon.
Drop does not contact the parts beyond the plastic tape in the whole process, thereby mechanism need not wiping.During dropping liquid, need the certain sample interval of control, sample room can be in contact with one another and pollute.When using the multichannel pipettor of Biochemical Lab's 12 passages commonly used; This pipettor can be by disposable 12 duplicate samples that splash into of certain intervals; System controls the corner of rolling wheel motor at interval according to this, and sample passes through fibre-optical probe successively, and synchronous with the detecting device sequential; Order is carried out the absorbance of 12 samples and is measured, and can realize high throughput testing.Mechanism also can cooperate robotic arm, constitutes automatic testing station, is specially adapted to Bioexperiment such as genescreen.When liquid need reclaim, available pipettor was collected at the rear roller place.As do not need to reclaim, can add a sponge at the rear roller place and directly wipe sample.
In a typical design, film bandwidth 5mm made of plastic, thickness 0.1mm, slit width 1mm.Optical fiber core diameter 0.4mm, drop form the thick cylinder of 1mm diameter 0.8mm at the probe place, required sample volume is 0.6uL.The sample room minimum spacing is calculated with 4mm, and a volume film band is 100 meters, then enough measures 25000 samples.With the plastic density is that about 2000Kg/m3 calculates, and only consumes the about 100g of plastics, is fully feasible economically.System's fully automatic operation under computer control, each sample only need about 2 second time, thereby can realize the per hour high flux screening of the highest 1800 samples, and can move Maintenance free round the clock, only need regular replenishment film band.Most of biological experiment uses the UV-VIS spectrophotometry test sample, thereby needs the film band transparent to 220nm to 900nm wave spectrum, does not react with common solvent.Fluorinated ethylene propylene copolymer (FEP) is a kind of chemically inert soft plastic, and good corrosion resistance is arranged; Transparency is excellent on the optics, and refractive index is low, and stronger anti-irradiation ability is arranged, and at visible region transparency is preferably arranged, and at the dark purple outskirt of 220-300nm good transmissivity is arranged also, thereby is the preferred material of making film band according to the invention.
Polystyrene (PS) and polymethylmethacrylate (PMMA) also have transparency preferably to visible light, but the transmissivity below the 270nm wavelength is lower, is applicable to the visible light analysis.These two kinds of material prices are lower than FEP, also can be used for making the film band.Above-mentioned material can be processed band shape with extrusion molding or drawing process.
When making slit and the cambered surface in micro-pond, if use metal material, can adopt CNC milling machine, cambered surface should polish smooth.Also can processing mold, with plastics or these parts of aluminium casting.After the moulding, make the optical fiber micropore with laser, fiber cores is passed micropore after, use adhesive curing, polish slit inboard fiber end face until reaching the optical surface requirement with a thin mill then.Another kind of job operation is amalgamation again after the vertical dimidiation in micro-pond is processed respectively, the difficulty that can avoid processing slit.
It should be noted last that; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to instance the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the spirit and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
