The invention relates to a set of photometric vats meant to be used in modular apparatuses with the view of determining concomitantly the composition and the concentration of chemical species on spectral way, and also with the view of tracking the microscopic image of some biological or chemical species in liquid solutions on optoelectronic way. For this purpose, there is used a modular structure comprising an optical transmission microscope (M), a miniature spectrometer (S) with diode array detector and several modules (MC1, MC2, MC3) of spectrometric vats, the entire system being managed by a computing technique (T). The first vat module (MC1) is destined to classic spectrophotometric determinations and comprises a body (16) of transparent methyl polymethacrylate and consists of two vats (Cand C), one vat being destined to the liquid probe to be analysed and the other one to the solvent, the top of the body (16) being covered with a thin lamella (17) meant to remove the liquid probe in excess into a collecting channel (c). The second vat module (MC2) is destined to the serial analyses and comprises a body (18) of transparent methyl polymethacrylate and consists of a row of eight vats (C...C), the first vat (C) being destined to the solvent and the other seven to different probes of various compositions and concentrations, the top of the body (18) being covered with a thin lamella (19) meant to remove the probe in excess into a collecting channel (c). The third vat module (MC3) is destined to determine the linearity limit of Lambert-Beer law depending on the layer thickness and concentration and it consists of a plastic transparent body (20) and comprises eight vats (C...C) and the top of the body (20) is covered with a thin lamella (19) meant to remove the probe in excess into a collecting channel (c). |
