Embodiment 1

[0035] A stepped multi-light path cuvette, comprising a cuvette body, a stepped cuvette platform 2, and a sliding stop 3 (see figure 1 ), the cuvette body is a stepped cuvette 1, and a plurality of steps I101 are arranged on the stepped cuvette; side, and the stepped cuvette platform 2 is provided with a step II 201 that matches the step I of the stepped cuvette, and the stepped cuvette platform 2 is an opaque body made of opaque material ; The sliding block 3 is supported on the other side of the stepped cuvette 1 . When in use, the stepped cuvette 1 is placed on the stepped cuvette platform 2, and the left side is supported by the sliding block 3. Move the sliding stop 3 to the left, and the stepped cuvette 1 can be lowered step by step (see figure 2 ). The incident light S enters the stepped cuvette 1 from the bottom of the sliding block 3, and the more the stepped cuvette 1 descends, the longer the optical path is. Therefore, the number of lifting stages through the st...

Abstract

The invention provides a step type multi-optical path cuvette and relates to a cuvette. The step type multi-optical path cuvette comprises a cuvette body, a step type cuvette table, a sliding baffle block, wherein the cuvette body is a step type cuvette, and a plurality of steps I are arranged on the step type cuvette; the step type cuvette table is arranged on one side of the step type cuvette, steps II matched with the steps I are arranged on the step type cuvette table, and the step type cuvette table is a light-proof body; and the sliding baffle block supports the other side of the step type cuvette. According to the step type multi-optical path cuvette, the optical path is regulated by increasing and decreasing the number of the steps of the step type cuvette, the requirements of multi-optical path measurements can be simultaneously met, the use is convenient, the entry of stray light can be avoided, and the addition of samples can be conveniently controlled; and samples with series of concentrations do not need to be prepared during rough measurement, operations such as semi-quantitative dilution can be directly carried out in the cuvette, so that the measurement conditions can be conveniently selected, and the sample amount can be further saved. The step type multi-optical path cuvette is particularly applicable to field measurement use of spectrographs.

Description

technical field [0001] The invention relates to a cuvette, in particular to a stepped multi-light path cuvette. Background technique [0002] Transmission is an important way of spectroscopic and optical measurements, and usually liquid measurements are done through cuvettes. Due to the relationship between the detection limit and the sample concentration, it is usually necessary to dilute the sample or replace the cuvette to adjust the light path. The current measuring instruments are all solved by configuring a series of cuvettes with different optical paths, but the disadvantages are that it is troublesome to calibrate and clean the cuvettes, and the large number of components is not easy to carry and store, especially for on-site measurement. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a step-type multi-light path cuvette to solve the problems existing in the prior art that the cuvette is troublesome to ...
