The present invention relates to a multi-emission spectral analysis method using a multi-band type color selection mirror and a multi-emission spectral analysis apparatus using the same.

Fluorescence refers to light generated when light is irradiated on a sample, when the energy state inside the sample transitions from a ground state to an excited state and returns to the ground state within a few nanoseconds within a short time. Phosphorescence is similar to fluorescence but when it returns to the ground state, it emits light in a delayed time rather than fluorescence because it passes through the triplet state, which is an intermediate energy level.

The emission spectrometer is a device used for analyzing the optical and photochemical properties of a sample by measuring fluorescence or phosphorescence generated from a sample irradiated with light by wavelength and clarifying the microstructure of the material. Such an emission spectrometer can be applied to various fields such as biotechnology and genetic engineering such as DNA structure analysis and DNA sequencing, environmental field such as analysis of the content of organic matters in water, analytical chemistry such as calculation of chemical reaction and quantum efficiency, Etc., as well as in the field of polymeric compound quantification, film coating, and the like.

1 is a schematic view schematically showing a configuration of a conventional general emission spectrometer.

1, in a conventional emission spectrometer, monochromatic light coinciding with an absorption wavelength of a phosphor attached to a sample 105 placed on a plate 104 in a white light 101 is transmitted through a first optical filter 102 Select. The path of the monochromatic light 103 having the selected absorption wavelength is adjusted through a single band dichroic mirror 108 to irradiate the sample 105 through the objective lens 106 and the second optical filter The light that matches the coloring wavelength of the light emitting body of the sample 105 from the light 107 generated by the light emitting body of the sample 105 passed through the objective lens 106 and the single wavelength color separating mirror 108 And provides it to the light receiving unit 110. On the other hand, the light receiving unit 110 is realized by various light emission analyzing devices, and detects the coloring wavelength of the light emitting body attached to the sample 108, so that specific information of the sample 105 can be confirmed.

However, since the conventional emission spectroscopic analyzer has a structure for obtaining a single light emission image according to the light irradiated to the sample 105, the light emission image is obtained by irradiating various light, There is a problem that it is not suitable to observe the accurate shape of the image.

In order to solve such a problem, a multi-emission spectrometer has been developed which includes a plurality of light sources so as to irradiate various light to the sample 105. However, in the conventional multi-emission spectrometer, A filter and a single-wavelength color-separating mirror, which are light sources, must be mechanically replaced depending on the type of light to be irradiated onto the sample 105, There is a problem.

That is, since separate electronic and mechanical equipments are required to replace the monochromator, the filter, and the single-wavelength color discriminating mirror included in the light source unit of the conventional multi-emission spectrometer, Mechanical vibrations are generated to cause malfunction of the device, and a separate time is consumed to replace the light source unit and the filter, so that a desired luminescent image can not be obtained quickly and easily. Therefore, it is required to develop a multi-emission spectrometer capable of easily and rapidly obtaining a large number of light emission images even without mechanical movement.

Researches for multi-emission spectroscopic analysis have been actively conducted so far and include a plurality of image acquisition units corresponding to the number of irradiated light sources to thereby easily and rapidly analyze a plurality of light emission images without mechanical movement. (Patent Document 1). However, since the light emission image observing apparatus includes a plurality of image acquisition units in a limited space, the structure is complicated, requiring a high degree of proficiency in the production process, and there is a problem that the optical arrangement can be easily turned on even a small impact.

Thus, the present inventors confirmed that a multi-emission spectrometer using a multi-wavelength monochromatic light source and a multi-wavelength color selective mirror can measure a plurality of emission spectral data at various monochromatic wavelengths without mechanical movement for replacing the light source and the filter Thus completing the present invention.

The reflection type emission spectroscopic analyzer according to the present invention can be used as a monochromatic filter for separating monochromatic light from a light source when multi-emission spectroscopic analysis is performed by using monochromatic light and multi-wavelength color selective mirror by a multi-wavelength monochromatic light source, The luminescence can be measured without mechanical replacement of a single-wavelength color-selective mirror in order to measure the change in the luminescence wavelength generated from the sample by a monochromator and a wide range of monochromatic light.

Therefore, the reflection type emission spectrometer of the present invention can be applied to the field of biotechnology and genetic engineering such as DNA structure analysis and DNA sequencing, the environmental field such as the content analysis of organic matter or inorganic matter in water quality, Such as analytical chemistry such as food and agricultural fields such as detection of luminescent materials in foods, as well as quantitative determination of polymer compounds, film coatings, and the like.

Hereinafter, the present invention will be described in detail with reference to examples.

However, the following examples are illustrative of the present invention, and the present invention is not limited to the following examples.

Principle of sample analysis of transmission type emission spectrometer

The process of analyzing a sample using the transmission electron emission spectrometer according to the present invention can be understood by the following analysis example.

A spectrophotometer (SM240, Korea Spectral Products Co., Ltd.) for measuring the wavelength of light passing through each component of the transmission type emission spectrochemical analysis apparatus according to the present invention is provided in each section of the analyzing apparatus (for example, The positions of 202, 202 ', 202', 204, 207 and 209 of the transmission type luminescence analyzer are checked. The wavelength of light passing through each section is measured to confirm the operation principle of the transmission type emission spectrometer. Thereafter, the transmission type emission spectroscopic analysis (Rhodamin 6G) is fixed to the sample part and the light source part is operated to measure the sample (Rhodamin 6G) at about 505 nm to 560 nm suitable for analyzing the sample (Rhodamin 6G) only In order to confirm the effect of the second color discriminating mirror 207 of the spectroscopic analyzer on the change of light reaching the detecting unit 208, When the color discriminating mirror 207 is mounted or not, the wavelength of the light passed through each of the sections is measured.

Referring to FIG. 4, when the light 204 having an undesired wavelength exists in the monochromatic light 202 to be irradiated, the first color separating mirror according to the present invention removes the light 204 and reflects only the monochromatic light 202 ' And perform selection. For example, when the first color selecting mirror 203 is irradiated with light having a wavelength of about 600 nm to 660 nm from the light source 201, unwanted light of about 630 nm to 660 nm is transmitted and removed, It can be seen that the light 202 'of about 600 nm to 640 nm required for the analysis is reflected and selected (see the graphs 202, 202' and 204 of FIG. 4).

In addition, the second color-separating mirror can not excite the target by separating the monochromatic light 202 'reflected from the first color-separating mirror from the emitted light 207 emitted from the target, so that the transmitted monochromatic light 202' It is possible to prevent the detection unit 208 from reaching the detection unit 208. For example, it can be seen that the light 202 'reflected by the first color-separating mirror is not reflected by the second color-separating mirror and thus is not transmitted to the detecting unit 208 (202' , 202 ", and 209 graphs).

Referring to FIG. 6, the transmissive emission spectrometer according to the present invention uses a multi-wavelength monochromatic light source and a multi-wavelength color selective mirror to selectively irradiate monochromatic light with monochromatic light and monochromatic light having different wavelengths, It was confirmed that it can be easily carried out without mechanical movement of the apparatus (refer to the graph 202 in FIG. 4 and FIG. 6).

In addition, the color selection mirror according to the present invention may be provided with monochromatic light 202 having a wavelength of about 500 nm to 560 nm irradiated from the light source 201, It can be seen that the light 204 having a wavelength of not more than about 520 nm to about 540 nm is selectively removed by transmitting the light 204 and only the monochromatic light 202 ' 202, 202 ' and 204 graphs of FIG.

Further, as can be seen from the wavelength of the light reaching the detection unit 208 due to the presence or absence of the second color selection mirror, the second color selection mirror can not excite the target existing in the sample unit 205, more accurate target information is obtained by reflecting and removing the monochromatic light 202 'having a wavelength of 540 nm to 540 nm and reaching the detection unit 208 only by emitting the light generated by exciting the target to improve the analytical performance of the spectroscopic analysis apparatus 202 ' and 207 graphs).
