Description

Technical Field

[0001] The utility model relates to the technical field of reagent kits, in particular to a mixed reference material reagent kit. Background Art

[0002] Raman scattering is a typical inelastic scattering, which was first discovered by Indian physicist Raman in 1928. However, the signal of traditional spontaneous Raman scattering is very weak, and the scattering cross-section of a typical Raman mode is only 10-30 cm 2 . Based on this, a variety of Raman signal enhancement technologies have emerged, and the typical representative is Coherent Raman Scattering (CRS) technology. Coherent Raman scattering is a coherent excitation process. Classical optics believes that the interference beat frequency of a two-color laser field drives molecules to perform forced vibrations, that is, the frequency difference (ωP - ωS) between the pump laser and the Stokes laser resonates with a certain Raman vibration mode of the molecule. In this process, all excited molecular vibrations have a definite phase relationship. Therefore, the optical field modulation caused by vibration can interfere constructively to achieve huge gain. Currently, there is no mixed reference material for coherent Raman calibration. At present, when in use, multiple single components are used for calibration, the operation is cumbersome and there is no unified standard. In the prior art, during the sampling process of a sample, different tools are needed for sampling, and the various required tools are usually scattered in different positions, so that it takes time for the experimenter to find and sort out the sampling tools.

[0003] The defects of the prior art are that, using the existing sampling device, the required sampling time is long and the sampling efficiency is low. And the glass slides used in the existing sampling process are traditional glass slides, and each glass slide can only collect one ratio of samples. When it is necessary to collect multiple samples with different ratios, multiple different glass slides need to be used, increasing the use cost.

[0031] The following further illustrates the present utility model in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the exemplified embodiments shall not be construed as limiting the present utility model.

[0032] Common Raman standard substances or general compounds cannot meet this requirement. Four Raman shift standard substances developed by the National Institute of Metrology, China, namely GBW13651 Raman shift standard substance of sulfur, GBW13652 Raman shift standard substance of naphthalene, GBW13653 Raman shift standard substance of cyclohexane, and GBW13654 Raman shift standard substance of paracetamol, are used for the verification / calibration of Raman shifts in different ranges. However, none of the substances have more than two characteristic peaks at intervals of 200 - 350 wavenumbers for frequency shift calibration in the range of 600 - 3500 cm-1, especially there is no signal in the range of 1800 - 2800 cm-1 (silent area).

[0033] Referring to Figures 1 to 9 As shown, the present utility model discloses a mixed standard substance kit for Raman shift calibration of a coherent Raman or other Raman system. The mixed standard substance kit includes a box body 1, and the box body 1 has an accommodation cavity.

[0036] Specifically, the slide assembly includes a slide storage box 301, at least one first slide 302 and at least one second slide 303. The first slide 301 is provided with a receiving portion, which includes at least one sample receiving groove 304 for accommodating samples. The second slide 303 is used to press against the first slide 301 during sampling to ensure that the samples can be stably received in the sample receiving groove 304.

[0037] Moreover, both the first slide 302 and the second slide 303 can be received in the slide storage box 301 for easy sorting and storage.

[0038] It can be seen therefrom that a mixed reference material kit to be protected by the present utility model is provided with a box body, a bottle body and a sampling unit. The box body can accommodate the bottle body and the sampling unit. The bottle body is used to place the mixed reference material. The sampling unit includes a carrier and a slide assembly. The carrier can support the slide assembly. The slide assembly includes a first slide and a second slide. The first slide has a receiving portion and can collect multiple different samples and avoid confusion. By covering the first slide with the second slide, the limitation of the samples can be achieved to prevent them from overflowing, so as to facilitate subsequent experiments and tests. The present utility model can simultaneously collect multiple samples with different ratios and can distinguish them to avoid interference between different samples, thereby effectively reducing the use cost. Moreover, each component in the kit can be reasonably accommodated in the box body, saving space, being convenient for storage, operation and sorting, and further improving the efficiency of the sampling work.

[0039] As a preferred embodiment, the number of the sample receiving grooves 304 is plural, and the plural sample receiving grooves 304 are arranged at intervals in sequence along the length direction of the first glass slide 301. A limiting bump 305 is further provided on the base, and the limiting bump 305 is configured to be arranged along the circumferential direction of each sample receiving groove 304, so as to further limit the sample in the sample receiving groove 304 and prevent it from overflowing.
